That was hilarious, when you said it just needs a buff out , and your finger goes right through the wing 😂 😂 😂 keep up the good work and comedy,love it
Nice find! One of the greatest estate cars ever made! If you do basic service properly - oils, filters, wear parts etc - it serves you for a long time. Common issues with these 2.5 TDI engines: sensors can die, vacuum lines and crankcase ventilation hoses and valves leak (old plastic parts break) turbo hose leaks, and because of these the mass airflow sensor gets the wrong value. Also the pre 2002 models had a bad camshaft lubrication system, so the lifters and camshafts can wear badly - can be updated to the newer version. Also the diesel pump can die caused by extreme heat, (the electronics can blow in them) if you constantly running on low fuel level - lack of cooling by the pumped diesel fuel. Have fun :)
Thanks for the info, János! A few people have mentioned about a boost leak now, so I'll have to take a look into that as that might be what is really causing the lack of power. And I agree; these are the greatest estate cars ever made!
Intake manifold pressure sensor mounted behind the nearside of the front bumper. It was as flat as a pancake with that knackered. Sounds just as you described, like a naturally aspirated engine. That was what mine was. I have a 2.5 tdi sport 163bhp fwd A6 C5 on an 03 plate. And they do have a cambelt, unlike moodyk1979 suggested. And even the later ones like mine still suffer from the bad camshaft lubrication. It sounds fine btw. I'm pretty sure it won't be an injector and it'll be a far easier job to change the Intake manifold pressure sensor than it will to take the diesel pipes off and change the injector.
Suggest that you buy a bluetooth OBD2 adaptor and put Torque on an android phone or tablet. With this you can set it up to view, with phone in windscreen holder in front of you, many real time driving values - voltage (to check charging and even voltage prior to starting, although heater plugs would drag this down), turbo boost pressure (you suggest that it is lacking go) as a minimum. Other apps may do the same. For the starting, your new book probably tells you how it is possible to look for resistance through heater plug connection (with supply wire removed) to the cylinder block. Number 27 on YT has recently done an A4 V6 diesel estate badged as quattro but was only FWD.
My father had a very cheap early 1994 A6 Avant which was just a rebadged 100 avant which he bought as a stopgap while his 4 year old Renault Laguna went French. It was so good that the Renault ended up scrap at 4 years old but the old 2 litre petrol Audi stayed with him for years and then he sold it onto an Antique dealer who would do over 150 miles a day in it and it never put a foot wrong and the body never had a sign of rot. I don’t think he ever serviced it as well and all it got was an occasional check of oil and coolant.
@@NotEconomicallyViable Luckily it’s an diesel and old VW diesel lumps are legendary and I know with Audi the rot started to set in in the early noughties (no pun intended lol) but I imagine a bolt on pair of pattern wings and a mop will bring it up a treat. I bought a cheap bolt on pattern wing for £30 for my E36 and to be honest once it was painted you would never know it had been replaced so hopefully a pair of wings will be dirt cheap and it’s been on the car 5 years and is still like new.
Pull the rocker covers both sides and check the cams and followers for wear, if there ok id continue, if the cams are worn the price to replace them may change your plans. Cam belt swap and pump belt would be high on my list too. Good luck.
Nino, I was having a bad day untill i watched your latest video and i am still laughing now great work. Good luck with this one, i cant wait for the next instalment.
If its consistently slow to start you may need to change the injectors or have to address some kind of fuel leak, check the rail pressure with your tool and make sure its in range
For the headlights, use some ArmorAll headlight wipes for a tenner at Halfords, they work brilliantly! (And are also extremely satisfying to use) As for the power, check for boost leaks in the pipework leading to and from the turbo as my diesel had a very similar issue. If they are Bosch injectors, they'll clean up pretty well with some steam through the nozzle but will need to be removed and disassembled. A good way to free them is soak them in oven cleaner for a bit and they should pop right out. Good luck!
She does sounds good...she need a good service (engine, gearbox and diff) and she will be good for another 100k. I have my workhorse 1.9tdi with 230k and those cars as long as you keeping up with services are amazing.
Get those injectors soaking in WD40, everyday give it a spray, for a week!! you need them coming out easy and not snapping in the head, you will need a clean up kit and new washers and each injector changed will need programming into the ECU, so check if you car computer can do that - you might even find that all the injectors need reprogramming in? maybe try that first? see what that does?
Also with the wings grab yourself some duck tape….. they will fail as they are because of SHARP edges. Tape over the crap and layer it up, wrap it under etc to make sure no sharp edges.
Had this engine 3 times. Good engines. One A6 with 280.000km (drove it for 25.000km in 13 months) which I bought with broken camshafts (500€ costs), one A8 with 375.000km (drove it for 20.000km in 12 months) first camshafts and no problems, one A4 with 220.000km (drove it for 40.000km in 25 months) first camshafts but second pump (no costs for me). I like them. Just don't do long life service (in any engine for that matter) and change oil every 5-8.000km in the AKE, AKN, BAU and BDG and you are pretty much safe. And remove the cover on the engine so the pump doesn't overheat. Never drive the tank empty so that the pump sucks air and burns up and you're safe. P.S. Good idea with the 01E swap, hell of a lot of work though, espacially with the two different sizes of the bell housings. The Diesel gear ratio is perfect for the 4.2 though. Own one as well.
You're an A6 2.5 connoisseur! In terms of the O1E swap I've seen people on forums do it and they never seem to have any problems with different bell housing sizes. They seem to imply it's a fairly straightforward swap. Or am I missing something? Yeah that 'box has two overdrive ratios if I'm not mistaken - perfect for the V8.
@@NotEconomicallyViable It may be, that the bellhousing for the 01E for the Diesel engines is an older form factor. As far as I know, converting the Automatik C5 4.2 to manual with the S6 gearbox is a pain. At least that's what I'm told by two people who did it twice each. Concerning the "overdrive", that's not really the case. The calculated gear speeds with the max rpm of the V8 are as follows: *5HP24 Automatik in 4.2 C5* 80,64km/h 130,90km/h 191,35km/h 287,98km/h 358,18km/h *01E in 2.5TDI quattro C5* 53,85km/h 98,07km/h 152,98km/h 224,45km/h 294,54km/h 359,95km/h So you see, the 6th gear is almost the same as the 5th gear in the 5HP24, which is perfect for highway driving. Up to 4th gear, it becomes a sprinting beast with times dropping from 6,9s 0-100 to 6s 0-100. Supercharger and a little less weight and it's a 4,5s 0-100 beast.
Dont worry about the needle lift sensor its only needed for checking the pump timing when the timing belt or the vp44 injektion pump is replaced probably its a boost leak or broken vacuum line to the turbocharger its not the reason for the missing power about the bad starting maybe air in the fuel line often they go bad (filter to vp44), glow plugs, g62 coolant sensor Since it is a 2002 its most likely an AKE they have a big problem with the cams and lifters Greetings from austria and an audi crazy guy who owns one A8 3.3tdi, eleven A6 C5 quattros, three A4 B6 and two A3 8L🤣
That's some great info there, thanks! I'm definitely going to have to check for boost leaks or broken vacuum lines then. And I've just been researching the VP44 - apparently there's an o ring that goes bad and that lets air into the system, so I'll probably look at replacing that. Eleven C5 Quattros!! Haha leave some for the rest of us!
I agree about needle lift sensor, it it has no effect on power. Also very comon problem is failed n75 valve(controls the turbo) and stuck vnt mechanism.
You say it ‘Shrewsbury’ - haha - your first go was about right. But actually as it was in Welshpool on the boarders most of its life I think it just got a lot treated to a lot of road salt, certainly more than around your way
I suggest that you give it a service (engine oil and all the filters), clean the headlights, replace both front wings and add some injector cleaner to the fuel tank before you even consider putting it in for an MoT. As it is, you're staring a guaranteed MoT failure in the face. I've had my 5th Gen Toyota Celica for nearly 3 years and I haven't MoTd it yet because I know it will fail.
He's putting it through the mot so he doesn't have to diagnose alllll the problems first, no point wasting time on all the little bits like headlights first when it might be rotten all underneath or has bigger issues all around For the sake of £40/50 may as well put it through so you know what needs to doing
I know where you're coming from but if he can't fix all the failures within the window for the free retest (10 working days), he'll have to pay for another test and they'll test everything again. With the free retest only the failure items are tested to check that they've been rectified.
I had a VW Passat 2.5tdi V6 and it was a fast car for what it is, check when the timing belt was done as it isn’t an easy job for someone who hasn’t done one before.
I used to own one of these Nino, but I had the 2.5TDI sport Quattro 180bhp, not sure if that’s the same or a 163, but they are very reliable engines, no cambelt but has a cam chain and needs to be checked to make sure it’s not stretched. Being a Manual it will be more relatable than the CVT Auto, but be warned that clutch replacements cost more as it’s a Quattro. Loved mine it had full works and had Bose sound system along with heated seats and electric rear blind. Let me know if you need any help as I know quite a lot about VW / Audi’s. Haven’t watched all the video yet, but be interesting to see what you will do with it :)
Love the retro colours that these cars were specced with. Certainly beats most modern cars with their dull black interiors that are specced just to help resale value
@@NotEconomicallyViable yes absolutely. My avant is the one in my profile picture and I got it because it needed a water pump and turned out it actually was a rear heater core hose not the pump (after I changed the timing and wp and thermostat) only really went for it because it had different interior. All black exterior and terracotta and black interior on the carpet door cards and dash top of dash was a grey to blend in to the beige a b and c pillers and white headliner I recently recovered in black stretch suede. Thinking of doing a rs clone on it when this 189,000 mile engine gives up the ghost.
If you don't junk the car and think about repainting this thing ... search for bed liner. There is a Mythbusters episode were they tested the toughness on a car. It turns the car into a tank! Amazing stuff!
Ok just watched it, first thing I would do is put a booster on the battery and first read the OBD faults, clear them then try starting, but it looks like the glow light didn’t come on for long enough, so could have failed glow plugs or glow plug relay or cabling etc. That length of time to take to start, is definitely glow or fuel draining back. When you turn it off after 10mins, does it start right up again? Full service first then go from there I would say with genuine parts or as close to :)
@@NotEconomicallyViable could definitely be but try recording the exhaust when you do another cold next day crank with the battery fully charged again, if it takes ages then you get a load of white smoke that will probably indicate the glow plug system is at fault. If you got an OBD reader for now you can see what codes are showing, if not it could be the fuel system, so a new diesel filter, and full service would be a good start buddy, but be warned, when changing the diesel filter, if you’re not careful it can be very hard to start diesels up again, can take a lot of cranking if the fuel filter hasn’t got any fuel already in the filter, and can also get air in the system, but start with one step at a time. If you’re going to keep that car and engine then definitely service it, oil is crucial for these engines and filters.
With all cars you’re unsure of, always clear all fault codes first, as even a flat battery can fire up loads of errors as the voltage is too low to power up the ECU and relative computers properly. Yeah the needle lift sensors can fail and you might find that fixes your performance issue, but the restriction in intake as I can’t remember if those engines have swirl flaps, which are notorious on many manufacturers cars to fail and break. But like I said, reset all the codes first bro :)
I think about renting a unit every single day lo. But where I live there is nothing to rent, and when something does come on the market it costs more than a house mortgage. One day I'll get one, but right now it's just not affordable.
Ooh brave, when I was looking for a big cheap old estate car I looked at a few A6s and they were all so bad I ended up buying a rusting W210 E class instead as being less trouble. :D
Best buy if you can find one is an early 2000s Mercedes 3.2 E320 CDI estate, the straight six. One of the best diesel engines Mercedes ever made and much better than the later V6. 45+ to the gallon and 0 to 60 in 7 seconds! My father has an immaculate 2005 saloon model in black, fully loaded and it drives beautifully.
@@popuptoaster Then you are certainly not a car fan, maybe a petrol head at best, or even someone whose experience with cars of all types is limited. I have driven over 600 different cars and some of the diesels have been awesome, fast off the mark, unrelenting torque, agile, high top end speeds and crazy fun. A twin turbo BMW diesel has better performance and is more fun to drive than a majority of petrol cars. I like both petrol and diesel cars as I am not narrow minded and appreciate the best in both types thanks to having been able to drive so many.
@@MiracleMitch You are just wrong, simple as and I question your experience of decent petrol engined cars if you think that about diesels, in cars they have narrow power and torque bands and most with any decent power have lag, they sound terrible and don't rev very high so you are always in the wrong gear or waiting for boost if you suddenly want a turn of speed whole just driving normally. Sure, manufacturers can set them up to get a half decent 0-60 time but that means diddly squat in real world driving, if I ring the neck out of my car it will do low 5 seconds to 60 but it's in gear acceleration and throttle response at normal driving speeds you want, both of which are severely lacking in almost all of them. The fun in a car starts about 200bhp per ton in my opinion and few diesels ever get near that. If diesel engines were any good for sporty or quick driving they would be used in race cars but they just are not, I would put my 22 year old petrol V8 engined car up against any diesel even a "modern" one. I am also not anti diesel in the right situation, I drive trucks and my boat has an 11 litre diesel in it. As for you deciding who is a "car fan", that's just laughable you betray your lack of imagination with your first sentence, I have been messing with cars since i was a pre teen, have modified, built and even raced cars and bikes briefly, I am not nerdy enough to have kept count of the number of cars I've owned or driven, but my cousin once worked out I'd owned over 30 different Cortinas by the time i was 20, and that was many years ago, at one point I owned nine different cars at once and I still don't consider that I should be able to tell other people what grade of car person they are....🙄 The history of your high performance diesels says all you need to know about them, BMW started the trend when they saw a market in company car drivers that wee not allowed to buy petrol engined cars, the "sporty" diesel car was, and still is, a poor substitute for those who wanted a petrol engined car but who were unable to buy one for whatever reason, be that company policy or MPG (Which by the way is often not that much better if you try to drive them fast). So keep your insults to yourself, just because someone disagrees with you there is no need to exercise your fragile ego, you go out for a drive in your rattly old diesel and tell your self you are letting the guys in the petrol engined cars overtake you by choice. 🤣
Great video... another fine project.... just make sure the chassis is good mate... don't do loads of work if the chassis is rotten as a carrot and wouldn't pass an MOT 😶
Have you told number 14 about your new purchase, I noticed there was enough space to park it behind the Merc, they might be away on holiday but I bet number 16 were straight on the phone to them when another old croc came spluttering round the corner, they must of spat their pina coladas out when they got the news 😂😅😱
It’s like the RS6 from Layer Cake but not an RS6 and battered to fuck. At least the engine sounds alright, it should go again for what you want and you’ll probably find the wings and other bits cheap since it’s so old.
Wow, I’ve seen great A6 Avants with higher mileage. Love the number plate UY02UFK, could mean u got f…by ebay seller. 🤪 Love your enthusiasm for the merc coupe too. Look forward to the refurbishment, & best of luck!
Nice old audi they run forever i had a few of them the headlights can be refurbished easy enough if the turbo was gone it would be smoking badly so it ain't that youl get wings cheap enough get some wynn diesel treatment can help cleaning the injectors 👍
@@NotEconomicallyViable it is your project either way. I'm to in love with the avant to even look at a cupe (saloon?) However my 2.8 gas isn't enough being 2 bolt main and only 200hp but it is quattro and i will have to watch you v8 video to see if its awd or not because in this video you were super excited about the quattro part maybe add that in with the transmission to ruin 4 tires (tyres) at once. Cant wait to see what you come up with.
I’m a massive wagon fan, however the V8 models have flared wheel arches. It’d be too much work for me to cut the wheel arches off the saloon and weld them onto the wagon. Otherwise I’d V8 this wagon in a heartbeat
@@NotEconomicallyViable would you be able to fit the bumpers off the saloon or another saloon ( I hate to take apart a car just for some body panels leaving it apat)
So you do all your checks on Mileage discrepancy, or if it's been crashed/stolen or outstanding finance AFTER you've paid for it? interesting way of buying cars I guess lol :)
Not usually, but I did with the last two because even if there were issues it wouldn't have deterred me from buying them. Not when you're spending £500 lol
@@NotEconomicallyViable It's just the re-sale that would concern me a little if it had been crunched :) useful tool though for seeing the damage on the report
Oh absolutely, but I don't buy these cars to flip or make money. I thought that was what I was gonna do when I started the channel, but now I'm just in it for the learning and the sheer joy of it. I've lost money on all the cars so far 😅 🤷♂️
Easy headlight restoration for starters, bolt on new used front wings in colour. Bit of leather creme to refresh the leather and a few electrical issues. Should get some decent and varied videos out of this one. Time for cutting, welding and electrical diagnosis practise!! Can't wait! 😂 Weak lift pumps (in tank) are a common issue for mid 100k cars which goes with one of the code(s) you have, plus a slightly slow starter motor (often the solenoids get contamination around the internal coil unit and just need a clean). Common rail injectors are a few hundred pounds each new but used good ones can be sourced (PD injectors like mine in my 4 pot Passat are mega expensive and cost at least a couple of thousand to replace the set with new!
@@NotEconomicallyViable that’s a good description of the crustyness 😂 we just got rid of a 2002 vw Passat estate with over 180000 miles on it and not a spot of rust on the body. The abs pump and fuel pump went. I can’t understand how that Audi is so rusty?
You can't go wrong, a car like that for £500. 2002 I had a 94 Vauxhall Cavalier 2.5 GLS on Manual box. I gladly give £500 for a complete car like that in any condition!
No idea why this video was recommended to me ,,,,but absolutely loved it...Honest,funny,sarcastic,,,,,
2 new wings,and job done....🤣💯🤣💯💯💯💯💯💯
Haha glad to have you on board, Mark 👍🏻
yeah i love it when the algorithm shows me something really fun
C5 and C6 audi have aged so well, I think theyre so underrated and as you say early 00's is peak practical and affordable motoring 👌🏻
@6:57 If the structual parts are sound, it is mostly about swapping body panels or welding stuff.
It's becoming more and more apparent to me that I'm going to need to learn to weld real soon. Genuinely can't wait lol.
Been watching your videos for some time now, I think this is your bravest buy, good luck with this one Nino I'll be watching with great interest.

So you see, the 6th gear is almost the same as the 5th gear in the 5HP24, which is perfect for highway driving. Up to 4th gear, it becomes a sprinting beast with times dropping from 6,9s 0-100 to 6s 0-100.
Supercharger and a little less weight and it's a 4,5s 0-100 beast.
Thanks for that great info 👍🏻 We'll find out in a few months just how difficult the swap really is 😉
Dont worry about the needle lift sensor its only needed for checking the pump timing when the timing belt or the vp44 injektion pump is replaced probably its a boost leak or broken vacuum line to the turbocharger its not the reason for the missing power
about the bad starting maybe air in the fuel line often they go bad (filter to vp44), glow plugs, g62 coolant sensor
Since it is a 2002 its most likely an AKE they have a big problem with the cams and lifters
Greetings from austria and an audi crazy guy who owns one A8 3.3tdi, eleven A6 C5 quattros, three A4 B6 and two A3 8L🤣
That's some great info there, thanks! I'm definitely going to have to check for boost leaks or broken vacuum lines then. And I've just been researching the VP44 - apparently there's an o ring that goes bad and that lets air into the system, so I'll probably look at replacing that.
Eleven C5 Quattros!! Haha leave some for the rest of us!
No i want the all 😂😂
Only the 4.2 v8 allroad is missing in my collection 🥲
I agree about needle lift sensor, it it has no effect on power. Also very comon problem is failed n75 valve(controls the turbo) and stuck vnt mechanism.
Would you get an error code if it was the N75 or VNT?
Yes something like this boost pressure below control limit
Head lights should come clear with a good cutting compound and DA polisher, failing that wet n dry 800 then 2000 then 3000 grit
Check for air getting in to the fuel system for the elongated crank time. Diesel runs back to the tank. Should be a sealed system
Thanks for that, Malcolm. Where would be the most likely place air would be getting in? Hoses?
That happened on my Jeep it was the “O” rings on the diesel filter connection.
@@dougfields5798 exactly the same thing happened to my Saab. Had to park front facing down hill to stop the diesel running back to the tank.
@@NotEconomicallyViable fuel filter o ring
Cheers, gents
So black gaffer tape on the body ,and clean headlights with wd40 which will last a week or two and new mot no problems
You say it ‘Shrewsbury’ - haha - your first go was about right. But actually as it was in Welshpool on the boarders most of its life I think it just got a lot treated to a lot of road salt, certainly more than around your way
I suggest that you give it a service (engine oil and all the filters), clean the headlights, replace both front wings and add some injector cleaner to the fuel tank before you even consider putting it in for an MoT. As it is, you're staring a guaranteed MoT failure in the face. I've had my 5th Gen Toyota Celica for nearly 3 years and I haven't MoTd it yet because I know it will fail.
He's putting it through the mot so he doesn't have to diagnose alllll the problems first, no point wasting time on all the little bits like headlights first when it might be rotten all underneath or has bigger issues all around
For the sake of £40/50 may as well put it through so you know what needs to doing
I know where you're coming from but if he can't fix all the failures within the window for the free retest (10 working days), he'll have to pay for another test and they'll test everything again. With the free retest only the failure items are tested to check that they've been rectified.
in 2023, a car like that in the exact same condition, in the US, would cost 5 grand minimum
Hi Nino. Just a thought but maybe you could use a6 allroad plastic wheel arch cowls to repair over the rot on the wings?
Gonna fail straight away on the front wings. Love the video
Apparently it's only the sharp edges that are an MOT failure, so gaffer taping them up will mean it'll pass the MOT 🤷♂️
Nothing wrong with those wings !! Bit of lining paper will sort that out 😂😂
I had a VW Passat 2.5tdi V6 and it was a fast car for what it is, check when the timing belt was done as it isn’t an easy job for someone who hasn’t done one before.
I'll see if I can find when/if it was done 👍🏻
I used to own one of these Nino, but I had the 2.5TDI sport Quattro 180bhp, not sure if that’s the same or a 163, but they are very reliable engines, no cambelt but has a cam chain and needs to be checked to make sure it’s not stretched. Being a Manual it will be more relatable than the CVT Auto, but be warned that clutch replacements cost more as it’s a Quattro. Loved mine it had full works and had Bose sound system along with heated seats and electric rear blind. Let me know if you need any help as I know quite a lot about VW / Audi’s.
Haven’t watched all the video yet, but be interesting to see what you will do with it :)
Haha if only Facebook Marketplace had a 'buy it now' button. That'd spice things up a bit
I paid 750 usd for my 99 a6 avant thought I had the cheepest one. Good find. Mine came with terracotta interior
Love the retro colours that these cars were specced with. Certainly beats most modern cars with their dull black interiors that are specced just to help resale value
@@NotEconomicallyViable yes absolutely. My avant is the one in my profile picture and I got it because it needed a water pump and turned out it actually was a rear heater core hose not the pump (after I changed the timing and wp and thermostat) only really went for it because it had different interior. All black exterior and terracotta and black interior on the carpet door cards and dash top of dash was a grey to blend in to the beige a b and c pillers and white headliner I recently recovered in black stretch suede. Thinking of doing a rs clone on it when this 189,000 mile engine gives up the ghost.
not economically viable . do it . great content . dont give up . really enjoy you videos . very unique and will only grow
I appreciate that!
If you don't junk the car and think about repainting this thing ... search for bed liner.
There is a Mythbusters episode were they tested the toughness on a car.
It turns the car into a tank!
Amazing stuff!
I'll take a look - cheers
Ok just watched it, first thing I would do is put a booster on the battery and first read the OBD faults, clear them then try starting, but it looks like the glow light didn’t come on for long enough, so could have failed glow plugs or glow plug relay or cabling etc. That length of time to take to start, is definitely glow or fuel draining back. When you turn it off after 10mins, does it start right up again? Full service first then go from there I would say with genuine parts or as close to :)
Thanks for that, bud. When I start it again after 10 mins it starts up easier than it does from cold, but still not great. Is that the glow plugs?
@@NotEconomicallyViable could definitely be but try recording the exhaust when you do another cold next day crank with the battery fully charged again, if it takes ages then you get a load of white smoke that will probably indicate the glow plug system is at fault. If you got an OBD reader for now you can see what codes are showing, if not it could be the fuel system, so a new diesel filter, and full service would be a good start buddy, but be warned, when changing the diesel filter, if you’re not careful it can be very hard to start diesels up again, can take a lot of cranking if the fuel filter hasn’t got any fuel already in the filter, and can also get air in the system, but start with one step at a time. If you’re going to keep that car and engine then definitely service it, oil is crucial for these engines and filters.
With all cars you’re unsure of, always clear all fault codes first, as even a flat battery can fire up loads of errors as the voltage is too low to power up the ECU and relative computers properly. Yeah the needle lift sensors can fail and you might find that fixes your performance issue, but the restriction in intake as I can’t remember if those engines have swirl flaps, which are notorious on many manufacturers cars to fail and break. But like I said, reset all the codes first bro :)
Thanks for all that, mate. I'll take a look at it all 👍🏻
Keep going this is all good content. Have you considered renting a unit to work on your cars.
I think about renting a unit every single day lo. But where I live there is nothing to rent, and when something does come on the market it costs more than a house mortgage. One day I'll get one, but right now it's just not affordable.
I am Audiwan Kenobi and I approve of this purchase.
Haha brilliant 😂
If its lacking power,i'd check egr valve first,to see if that's not blocked. IF it is still there that is.
Nice one. So I'm guessing that lots of these cars had an EGR delete?
You should clean the engine with additive in your dieseltank.
Yeah a couple of people have suggested that now. Any particular products you recommend?
It`s an old diesel, give it two heat cycles when it`s cold.
Unplug air mass meter see if it pulls any better miles and age probally due one
I remember my uncle had an Audi estate car & it had 250k miles on it when I last saw the car
OL is open loop or open circuit, basically its been a sensor too long
Out with the old and in with the new...ish
I hope you never have to take the pinch bolts out of the front suspension. I had to scrap an A4 for the sake of those two bolts
Oh dear Simon
Ooh brave, when I was looking for a big cheap old estate car I looked at a few A6s and they were all so bad I ended up buying a rusting W210 E class instead as being less trouble. :D
They seem to be hit and miss. Some are in great condition and others not so much
Best buy if you can find one is an early 2000s Mercedes 3.2 E320 CDI estate, the straight six. One of the best diesel engines Mercedes ever made and much better than the later V6. 45+ to the gallon and 0 to 60 in 7 seconds! My father has an immaculate 2005 saloon model in black, fully loaded and it drives beautifully.
@@MiracleMitch Don't like diesels, to slow and not fun to drive, even a big turbo OM606 is only fun for about ten minutes then they are just annoying.
@@popuptoaster Then you are certainly not a car fan, maybe a petrol head at best, or even someone whose experience with cars of all types is limited. I have driven over 600 different cars and some of the diesels have been awesome, fast off the mark, unrelenting torque, agile, high top end speeds and crazy fun. A twin turbo BMW diesel has better performance and is more fun to drive than a majority of petrol cars. I like both petrol and diesel cars as I am not narrow minded and appreciate the best in both types thanks to having been able to drive so many.
@@MiracleMitch You are just wrong, simple as and I question your experience of decent petrol engined cars if you think that about diesels, in cars they have narrow power and torque bands and most with any decent power have lag, they sound terrible and don't rev very high so you are always in the wrong gear or waiting for boost if you suddenly want a turn of speed whole just driving normally.
Sure, manufacturers can set them up to get a half decent 0-60 time but that means diddly squat in real world driving, if I ring the neck out of my car it will do low 5 seconds to 60 but it's in gear acceleration and throttle response at normal driving speeds you want, both of which are severely lacking in almost all of them.
The fun in a car starts about 200bhp per ton in my opinion and few diesels ever get near that. If diesel engines were any good for sporty or quick driving they would be used in race cars but they just are not, I would put my 22 year old petrol V8 engined car up against any diesel even a "modern" one. I am also not anti diesel in the right situation, I drive trucks and my boat has an 11 litre diesel in it.
As for you deciding who is a "car fan", that's just laughable you betray your lack of imagination with your first sentence, I have been messing with cars since i was a pre teen, have modified, built and even raced cars and bikes briefly, I am not nerdy enough to have kept count of the number of cars I've owned or driven, but my cousin once worked out I'd owned over 30 different Cortinas by the time i was 20, and that was many years ago, at one point I owned nine different cars at once and I still don't consider that I should be able to tell other people what grade of car person they are....🙄
The history of your high performance diesels says all you need to know about them, BMW started the trend when they saw a market in company car drivers that wee not allowed to buy petrol engined cars, the "sporty" diesel car was, and still is, a poor substitute for those who wanted a petrol engined car but who were unable to buy one for whatever reason, be that company policy or MPG (Which by the way is often not that much better if you try to drive them fast).
So keep your insults to yourself, just because someone disagrees with you there is no need to exercise your fragile ego, you go out for a drive in your rattly old diesel and tell your self you are letting the guys in the petrol engined cars overtake you by choice. 🤣
Great video... another fine project.... just make sure the chassis is good mate... don't do loads of work if the chassis is rotten as a carrot and wouldn't pass an MOT 😶
Unless you want to hone your welding skills.
I definitely need to get underneath and have a good look. Hopefully it's just the wings that are rotten
Have you told number 14 about your new purchase, I noticed there was enough space to park it behind the Merc, they might be away on holiday but I bet number 16 were straight on the phone to them when another old croc came spluttering round the corner, they must of spat their pina coladas out when they got the news 😂😅😱
Hahaha! 😂 I haven't, but they'll be finding out about it soon enough when it gets parked up there 😅
I've got one ...a 3l V6...it's a nice car...surprisingly economic. Buy a good diag
It’s like the RS6 from Layer Cake but not an RS6 and battered to fuck. At least the engine sounds alright, it should go again for what you want and you’ll probably find the wings and other bits cheap since it’s so old.
Oh god, don’t get Nino started on the Layer Cake car…he dreams about it often 😂
I made Naomi watch Layer Cake with me just so I could see Daniel Craig razzing around in that RS6. Definitely gonna buy one.

@@NotEconomicallyViable it is your project either way. I'm to in love with the avant to even look at a cupe (saloon?) However my 2.8 gas isn't enough being 2 bolt main and only 200hp but it is quattro and i will have to watch you v8 video to see if its awd or not because in this video you were super excited about the quattro part maybe add that in with the transmission to ruin 4 tires (tyres) at once. Cant wait to see what you come up with.
I’m a massive wagon fan, however the V8 models have flared wheel arches. It’d be too much work for me to cut the wheel arches off the saloon and weld them onto the wagon. Otherwise I’d V8 this wagon in a heartbeat
@@NotEconomicallyViable would you be able to fit the bumpers off the saloon or another saloon ( I hate to take apart a car just for some body panels leaving it apat)

Did the car live by the sea? That would be a reason for how crusty it is.
That's a great question. I'll take a look where the services were completed and see if that will give us an idea 👍🏻
I know the car was originally registered in Oxford as it has an O prefix.
These old audi's whit the 2.5 tdi are used cars from hell. Believe me .

Easy headlight restoration for starters, bolt on new used front wings in colour. Bit of leather creme to refresh the leather and a few electrical issues.
Should get some decent and varied videos out of this one. Time for cutting, welding and electrical diagnosis practise!! Can't wait! 😂
Weak lift pumps (in tank) are a common issue for mid 100k cars which goes with one of the code(s) you have, plus a slightly slow starter motor (often the solenoids get contamination around the internal coil unit and just need a clean). Common rail injectors are a few hundred pounds each new but used good ones can be sourced (PD injectors like mine in my 4 pot Passat are mega expensive and cost at least a couple of thousand to replace the set with new!
Cheers for that bud. I'm definitely gonna be learning to weld, but now right now. Got lots to do in the meantime
How is that car so rusty and crusty for a car with only just over 100k miles, was the previous owner a scuba diver?

It seems front wings on this era of German cars tend to rot badly golf 4 and bmws are bad.
I had a MK 5 Golf a couple years ago and it was the same story with that car.
You're program reminds me of the older Wheeler Dealer show..... bud throw that engine cover away. Nothing but a heat collector..
I think that's a compliment... 😅 Yeah, you're probably right about the engine cover. What are they even for anyway?
Its a race car losing weight
Nature's weight reduction 😅
Did Audi use the salt based galvanising on that model😅
Either that or the wing is made from recycled ice cream cones 😂
@@NotEconomicallyViable that’s a good description of the crustyness 😂 we just got rid of a 2002 vw Passat estate with over 180000 miles on it and not a spot of rust on the body. The abs pump and fuel pump went. I can’t understand how that Audi is so rusty?
