I decided a long time ago that I’m a car recycler. A usually move on my cars cheaply to those who seem to need a cheap car. I’ve recently started giving away my project cars once they’re done, which is completely economically nonsensical. But it makes me happy and keeps me off the streets.
I'm driving a 33yr Volvo 740 wagon that originally my dad's car. And everyone knows how well European cars age compared to their Japanese counterparts. 😅🙄
I was the same as you many years ago I was helped by hains manuals. It is like having an expert mechanic on the car you are working on giving you advice. They also have a section on how to diagnose a problem. good luck.
Just recently started watching your videos. You are certainly try. 2 things that come to mind, you could always take classes to learn mechanics, you really really need a garage, workshop to work in. The other is the way you go at seeing if a part works, by buying a replacement and seeing if that works, that must hurt the wallet. But i must admit that the way you are doing it, teaching yourself must be very satisfying. Regards Rickie all the way from Australia
The thread on the viscous fan coupling is a regular right-hand thread (unscrews anti-clockwise). That’s according to the official Audi workshop manual and multiple forum posts backing this up 👍🏻🔧🔧👨🏼🔧
It looked like you were going clockwise on the fan nut in the video? As much as I know what direction normal threads go, I have often spent ages fighting a bolt that's awkward just to find out I was tightening it all along 😂
You have an amazing attitude! Couple thougths: Viscous fans are LEFT threaded on petrol engines. I've removed one two days ago. I'll check my mate"s car tomorrow, he has a 2.5TDI A6, and a spare engine. Do not cut the viscous shaft, finding any used in good condition is rare, and bloody expensive. The cams look okay, I had seen worse, and much worse as well - that was so worn, the rocker arms fell off... If you can find a good used set, replace it with that, any other solution is extremely expensive, and aftermarket parts do not last as long, as any used, original Audi in relatively good condition. Remowing the glow plugs: remove the dust next to them, if possible, use penetrant oil, heat it up, loosen them while the engine is hot. Do not use too much force, you can try with max 20-25Nm loosening them. If you force it too much, they will snap. Be patient, try them loosen, tighten, slowly. By the way, working on diesel cars, you'll look worse than any coalminer... Wear your most hated clothes while fixing your car :D Nearly impossible to clean oily diesel smudges... Keep up the good work, you'll definitely learn a lot fixing it!
@@NotEconomicallyViable We've checked the spare engine, the viscous fan shaft is normal threaded on your car. Actually you can figure it out, by inspecting the fan blades. If it is rotating anti-clockwise, it is normal threaded. If it rotates clockwise, it is reversed. So, it doesn't depends on fuel type. However releasing the thread will require a huge leverage, use a pipe or any extension you can find. Yo can also remove the plastic fan - held by 4 pcs of screws, 10mm hex head. You're welcome! :)
The cams should be an even height all the way from one side to the other no troughs or high spots an even level smooth surface a couple of little scuffs Won’t hurt
Check the Camschafts. This is one of the number one issues. In the same way you can also renew the valve cover gasket. Besause they are often leaking oil there. If they are okay it is maybe a pulley or another component outside the engine. Often also the bearings are in their age and are worn out. What could be also possible is that one of the Injectors is leaking Diesel. You can check this with VCDS or there are plenty of Apps with OBD Adapter. Greetings from Germany!
Hiya Nino, agree with an earlier poster, think the rattle is probably belt tensioner, reason being it's very rev specific or dependent on rapid rev rise as opposed to constant (tappets/cam etc) easier way to check before you stripped all the bits off would have been just take the drive belts off...obviously not running it for long, just enough to check....oh and personally think cams look OK....as long as there no ridges on cam you should be OK....could be worse, been watching videos on Vag technic(amazing engine diagnostic/builder) and he recently done cam followers on s6? The followers self destruct due to design fault..Engine out, apparently the engine on this car needs to come out for lots of jobs!!! Think total bill was 9k!!! Audi wanted 24k for replacement engine!!! My last 5 cars and my aeroplane didn't come to that much... Anyway, good luck with your Audi Bill
So did your sort out the starting problems.would be nice to have some sort of continuity. What happened to the Mercedes you were playing with.has that been pushed to the back of the yard never to be seen again.
The engine sounds very healthy, I'd of thought your clunky noise is something external, when your doing the cambelt you'll probably come across it! Sounds a bit like the clutch on the air conditioning compressor to me!
Good car, good vid. Once you've done the timing belt, auxiliary belts and tensioners are all set and as they should be, you've properly serviced it, you've dealt with niggles such as sensors, maf etc. and there are no other visible faults, run as a daily for a while and if nothing else breaks, then you can sell with a clear conscience even if there are a couple of squeaks and rattles.
The nut on the fan you can not undo is left hand thread anti clockwise you are trying to undo wrong way you just tighten it up. The engine noise you should first chech valve clearance if ok you will see worn rocker too much play cause engine noise hope this helps Phil In stoke
You really need to find out what the actual noise is. You need somebody to blip the throttle while you have a look in the engine bay. My first thought was the viscous coupling. As other have said, most viscous couplings have a left-hand thread to stop them from coming undone when the engine is running. I don't know if that is the case with this A6. Bianca may be your least favourite sister but she's gorgeous.
@@NotEconomicallyViable he sound a little bit loud, try to check if the Flap have play or if the electronic part is good, if he's all good let it like that
I had one of these cars a good few years ago. I was a 1999 2.5tdi A6 avant. I replaced the cam followers which are under the camshafts and difficult to see. Audi in their infinite wisdom decided to have a long life service interval, something like 24000 miles. A really bad idea.
@@NotEconomicallyViable I have a 2006 Mercedes e320 cdi and that is on 8000 mile oil changes, which gets expensive when it takes 9 liters. Probably a bit over the top but I have owned it for 10 years and it never misses a beat.
I'm the same way, i bought a very poorly 3dr Fiat Stilo as a 'cheap' run around, so far spent double or maybe triple the purchase price cost on new parts and now bought a set of nice alloys and lowering springs for it. A sane person would have broke it for spares and cut their losses but no not me, i have to save them all.
I had that clicking noise on startup mainly for the first minute of so on my old Golf.. It seemed to come from the belt area and I changed the cam belt tensioner (and water pump plus belt ) and it’s been quiet as a church mouse since. I doubt the old girl isn’t even run in yet at that mileage anyway isn’t 02 brand new lol.
Good to know. It definitely sounds like it could be a tensioner - especially considering it only makes a noise when being revved. 02 most certainly is brand new haha
The treads on these are just like normal (so counter clockwise to undo). I would maybe suggest putting the car in the service position then see if it's possible to cut the plastic cover just above the fan. Hopefully then you can undo it and pull it down and it'll give you some more space. The noise you have sounds a bit like a failing tensioner which is roughly in the area you said it's coming from. If not, have a look at the crank pulley as they can cause a hell of a racket. Hopefully you can get to the bottom of it 🙂
Thanks for that, bud. I did think about cutting the plastic cover, but I'll do that as a last resort. I'll take a look at the tensioner and see what I can see 👍🏻
Totally with you, economic viable sense goes completely out the window, I’m not even sure man maths covers this one. However, you reach a point where you feel it’s almost your ‘duty’ to get the car to the best it can be…ask me how I know…. Good luck with this project Nino.
@@NotEconomicallyViable yea that’s reverse thread so you have to turn it the other way (tighten) to loosen it. Righty loosely in this case. Normally it’s lefty loosely righty tighty 😃
pitting on a smooth surface like that is called "spawling." really bad spawling is what creates the noise in a bad wheel bearing, and it starts with light pitting like that. now, that being said, i've seen cams that had light spawling on the lobes that ran for another 100k without going to bits.
Ake engine suffer from hollow cams that snap could be a dodgy follower? Just found you as I have an a4 with 2.5tdi but bdg engine,hope it's an easy fix could be something touching the fan.
Oh dear its very difficult to help from afar, but those camshafts look ok you would know if they are badly worn, these just look like typical used heat soaked engine parts, re the viscous coupling, they are opposite threads…… are you trying the right way. The noise is something rotating and id say its ancillary to the main engine from what i can hear, check play in turbo, check the fan itself and check all the various belt tensioners and pulleys. If needs be take off the belts u can and run engine, id dismiss all the easy stuff before diving into the engine.
I had one of the spanners jammed in underneath on the shaft so it was resting on a bumper mount so that I could use one hand to give it everything I had
Good thing about these Audis how u can unbolt the front panel and pull it forward to get access for doing the cambelt I did this on my a6. I know on the 1.9 the camshaft are known for going not sure on the 2.5 though. Them gloves look decent is there a link for them
Doesn’t the motor have a harmonic balancer on the crank pulley . Or possibly the duel mass flywheel both will cause the same noise when the engine spins faster ? Good luck
@@NotEconomicallyViable the harmonic balancer is situated on the end of the crank shaft at the very front of the motor. Once the rubber fails it will make metal to metal contact briefly
I'll probably go down that route. Whilst there is decent access in service mode it'll certainly make it that much easier for a noob like me to work more efficiently
I think I saw a Ratchets and Wrenches video once which described the process of removing the front bumper and radiator assembly to ready an Audi A6 for any major engine work. A $100 timing belt costs $900 in labour to change.
I have the a6 too with the 2.5 tdi ake 180hp and when I rev it over 2000rpm and when I release the throtle pedal its holding 1100-1300rpm. Would love if someone knew the answer to this . Thank you.
In my experience of old Audi's, once they start to go wrong you need to get rid of them immediately. Otherwise it is one issue after the other, as soon as you fix one issue another one will occur so it will never, ever be completely fixed. So you have bought 3 old Audi's, and all 3 of them have been an absolute nightmare........
The problem is, most people buy these cars cheap. They diagnose one problem, not knowing they may have more and they sell them. The next guy is a bit more thorough and discovers two problems. Drives it and after some time an old problem which hasn't been adressed shows up. Get's sold again and at some point they end up at someone like me or you. And the reason is because at one point people stopped servicing them properly. Had this with BMW, Mercedes, Toyota, Honda, doesn't matter. Although Toyota and Honda fail way more often in little annoying things. And feel crap after 20 years. On a positive note, you don't have all these problems with Fiat. They don't make it to the 20 years of age.
Audi makes it extremely labour intensive to change cam belts, while VW makes it quite easy. Same holding company. Many shared platform and engine parts. Go figure.
Just a thought are not the viscous coupling fans held on with reversed threads ? By the way great video again love your thought process while working through the symptoms. Noise maybe associated with a knackered tensioner. An automotive stethoscope can assist in finding locations of noises. 😊
Does to make that clanging noise just when you rev it or does it do it while the engine is sat at 2000rpm? I'm not 100& sure but on other vehicles I've worked on with a viscous fan they were a left hand thread.
@@NotEconomicallyViable well if it's not doing that noise at a constant rev then before going all out and pulling cams change what you know is broken i.e the engine mounting and go from there as with that not functioning correctly it could be that.
Names of cars, my Pug is called Bianca as she's in Bianca White, no offence to your sister. Frustrating are big cars as everything is manufactured to take such higher loads, I'd stick to smaller cars if I were you Nino.
No such thing as a cheap German car I’m from Australia & have been a mechanic for the last 12 years plus & I still cannot believe how cheap cars are in the UK. I can guarantee that the cam shaft will be very worn & may need replacing. All that carbon build it is quite literally terrifying me because I have had to de-carbon a couple of VW Jettas with the 1.9TDI and it wasn’t pretty. For both me & the customer who had spend £1300. For me to fix your Audi properly I would estimate about £3000-3500 to do it. I wish you good luck.
@@NotEconomicallyViable that is just my personal opinion based on the photos & videos you posted. It could be totally off the mark. Without standing in front of it & physically seeing the car. I am only guessing. It is also the worst case scenario I am giving. So don’t take it personally. I hope it works out for it should be a good car.
@@NotEconomicallyViable also don’t forget I am in Australia where anything German Audi,VW etc command a premium price tag. It costs a fortune to get parts in Australia it might be different in the UK. But we deal mostly with Japanese & American cars. Which cost 1/4 of what the German brands do.
I didn't realise there was such a premium down there on German rigs. Parts here really aren't too bad - main dealer prices are always quite high, but the aftermarket is extensive. For instance, I just purchased a Gates timing belt kit (the deluxe version that includes tensioners, water pump, thermostat etc) and it cost me £220 (382 AUD). Don't know what that might cost where you are. Parts for my Merc are different though - they're all scary expensive unless you buy all the Chinese rubbish.
@@NotEconomicallyViable you can double the price you paid for the timing kit to around £400 through an Australian supplier they add on shipping & other costs. Merc parts are astronomical here. For instance your 220E I would buy parts from the salvage yard. I wouldn’t even try buying anything new. We do have quite a decent Mercedes salvage industry that does refurbish things
Don't fall into the trap I always have. Buy the cer, spend loads getting it perfect then when there is nothing more to do I get bored with it, sell it & start the whole process again with another car.
Cams would be noisy all the time mate and so would broken loose rockers, my money would be on the throttle body closing shut. Sorry I can't be more help.
Mate I’ve just found your RUclips I love it man keep it up I would just like to ask please when did you get into mechanics? I’ve got major anxiety about it i I didn’t do good in school and got kicked out of college when I was 16 and couldn’t go back when I started mechanics I’m 22 and just started another mechanics course at college you seem to know a lot of just like to know when you started and how old you are now if that’s not to cheeky as I have such a passion about this to I just am bad at learning tbh and I feel like it’s to late
You can see the day when I first got into mechanics by going and watching my first video on the channel lol. Must have been about two years ago. The whole reason I started this channel was because I was fed up with where I was in life and I knew I always wanted to work on cars. So I had this idea that I could start a channel working on cars and teaching myself in my spare time and it might just be able to pay me some money. I knew absolutely zero when I first started. I just bought a cheap car, some cheap tools, and watched loads of RUclips videos of the specific repairs I needed to make. I tried for years to get apprenticeships, but I'm in my late thirties, so it's much much harder. At your age you've got absolutely nothing to worry about at all. If you give it your absolute all, work like crazy, always challenge yourself, and aim at what's good, you'll get to my age and you'll be in an incredible position. Good luck mate 👍👍
@@NotEconomicallyViable mate thank you for your lovely words and don’t worry your doing amazing your drive and Ambitions is next to none, inspiring. I’ve literally binge watched your channel I’m loving it keep up the good work man and I do tend to forget to click the like button on videos but I will have to go back and check and try to remember to support you! Your funny to mate guess I just need to get past the anxiety of doing stuff j on my drive infront of my neighbours Bevause they all nosey and drama about each other lol wel done starting the channel honestly mate you learn quick and its amazing to watch tbh
If the camshafts have pitting on them it means the hardening is breaking up and will only get worse. This car is turning in to a money pit so unless you intend keeping it and running it in to the ground I would get rid of it now.🤔
I named all my cars, my current car which is my dream car which I will never let go off(Toyota GT86) I named her Krystal after the fox in Star Fox as she is blue.
So refreshing to see a female that actually knows something about cars, it must be in the genes🤔 Most girls never ever open the bonnet let's be honest 🤣
I'm the same I get emotionally involved in my cars. Then can't bring myself to sell them. Its stupid and irrational but at least your not alone.

@@NotEconomicallyViable the harmonic balancer is situated on the end of the crank shaft at the very front of the motor. Once the rubber fails it will make metal to metal contact briefly
Often taking the whole front end off one of these to do a timing belt change is the preferred option, makes other things a lot easier to access too.
I'll probably go down that route. Whilst there is decent access in service mode it'll certainly make it that much easier for a noob like me to work more efficiently
I think I saw a Ratchets and Wrenches video once which described the process of removing the front bumper and radiator assembly to ready an Audi A6 for any major engine work. A $100 timing belt costs $900 in labour to change.
18:05 actually, it was a flying dragon;)
I have the a6 too with the 2.5 tdi ake 180hp and when I rev it over 2000rpm and when I release the throtle pedal its holding 1100-1300rpm. Would love if someone knew the answer to this .
Thank you.
The only way to tell if the camshafts are worn is too measure the journals with a Vernier caliper
The journals are not the problem,it's the cam lobes that are breaking up.
Did anyone tell you it is a left hand thread on the viscous fan?
If you watch the next video you'll see it isn't
Is the fan not a left hand thread. Maybe.
use a spanner which has better grip
hi mate I would see if it would pass M O T first before doing cambelt the if it needs a lot of work not bother with it OK 😉
I'm too far into it now haha. She's going to pass her MOT if it means I have to re-weld every component on her 😆
timing chain tension loose hitting 5he alloy cover or block or is it a belt
ok a belt...does it vvt?
In my experience of old Audi's, once they start to go wrong you need to get rid of them immediately. Otherwise it is one issue after the other, as soon as you fix one issue another one will occur so it will never, ever be completely fixed.
So you have bought 3 old Audi's, and all 3 of them have been an absolute nightmare........
Yeah pretty much - but I wouldn't have much of a channel if I bought cars with no issues 😉
Subscribed mate !!
Your undoing the nut on the fan the wrong way, they undo clockwise 😁
why don't you put some fresh oil in and see if the noise changes.also you might need to pull he front off the car and use a rattle gun
OMG 😍 beautiful sister & she knows about cars ☺️
The problem is, most people buy these cars cheap. They diagnose one problem, not knowing they may have more and they sell them. The next guy is a bit more thorough and discovers two problems. Drives it and after some time an old problem which hasn't been adressed shows up. Get's sold again and at some point they end up at someone like me or you. And the reason is because at one point people stopped servicing them properly. Had this with BMW, Mercedes, Toyota, Honda, doesn't matter. Although Toyota and Honda fail way more often in little annoying things. And feel crap after 20 years. On a positive note, you don't have all these problems with Fiat. They don't make it to the 20 years of age.
Audi makes it extremely labour intensive to change cam belts, while VW makes it quite easy. Same holding company. Many shared platform and engine parts. Go figure.
Those bolts loose, if you use a pneumatic hammer with a chissel.
5 hours with a typical Essex girl, you sir are a brave man, 😂🤣👍
Rusty spoons 😂😂 that brought back memories 😅
You have to do it in the voice haha
Just a thought are not the viscous coupling fans held on with reversed threads ? By the way great video again love your thought process while working through the symptoms. Noise maybe associated with a knackered tensioner. An automotive stethoscope can assist in finding locations of noises. 😊
I didn't even know an automotive stethoscope was a real thing, but now I do I might just have to get myself one!
That engine looks like a nightmare to work on everything so tightly crammed in
The fans are normally reverse thread
Does to make that clanging noise just when you rev it or does it do it while the engine is sat at 2000rpm?
I'm not 100& sure but on other vehicles I've worked on with a viscous fan they were a left hand thread.
When it revs. Driven it a couple of times up the driveway and didn’t make that noise
@@NotEconomicallyViable well if it's not doing that noise at a constant rev then before going all out and pulling cams change what you know is broken i.e the engine mounting and go from there as with that not functioning correctly it could be that.
Ok nice one - cheers bud 👍🏻
reverse threads on fan ?
Am I the only one shouting “it might be a left handed thread” at the TV
I doubt it haha. But it’s definitely a right hand thread. Checked the official documentation and checked multiple forum posts 👍🏻
The fan is reverse thred you have been tightening it rather than breaking it loose
It’s a left hand thread mate...
That sounds like a drivebelt idler or tensioner.
Nice one - will investigate further
Timing chain
Names of cars, my Pug is called Bianca as she's in Bianca White, no offence to your sister. Frustrating are big cars as everything is manufactured to take such higher loads, I'd stick to smaller cars if I were you Nino.
If you remove front end completly,bumper,complete bumper support with headlights,and radiators,it will be a piece of cake,thats how I work
Cool - I'll do that 👍🏻
No such thing as a cheap German car
I’m from Australia & have been a mechanic for the last 12 years plus & I still cannot believe how cheap cars are in the UK. I can guarantee that the cam shaft will be very worn & may need replacing. All that carbon build it is quite literally terrifying me because I have had to de-carbon a couple of VW Jettas with the 1.9TDI and it wasn’t pretty. For both me & the customer who had spend £1300.
For me to fix your Audi properly I would estimate about £3000-3500 to do it.
I wish you good luck.
I'm just gonna pretend I didn't read this comment haha 🫣😅
@@NotEconomicallyViable that is just my personal opinion based on the photos & videos you posted. It could be totally off the mark. Without standing in front of it & physically seeing the car. I am only guessing.
It is also the worst case scenario I am giving. So don’t take it personally. I hope it works out for it should be a good car.
@@NotEconomicallyViable also don’t forget I am in Australia where anything German Audi,VW etc command a premium price tag. It costs a fortune to get parts in Australia it might be different in the UK. But we deal mostly with Japanese & American cars. Which cost 1/4 of what the German brands do.
I didn't realise there was such a premium down there on German rigs. Parts here really aren't too bad - main dealer prices are always quite high, but the aftermarket is extensive. For instance, I just purchased a Gates timing belt kit (the deluxe version that includes tensioners, water pump, thermostat etc) and it cost me £220 (382 AUD). Don't know what that might cost where you are.
Parts for my Merc are different though - they're all scary expensive unless you buy all the Chinese rubbish.
@@NotEconomicallyViable you can double the price you paid for the timing kit to around £400 through an Australian supplier they add on shipping & other costs. Merc parts are astronomical here. For instance your 220E
I would buy parts from the salvage yard. I wouldn’t even try buying anything new. We do have quite a decent Mercedes salvage industry that does refurbish things
GLOVES!!!
It's a reverse thread on this coupling needs a wack and it will cone off dine hundreds of them
Cheers - I'll give that a go
Are you sure your not tightening the nuts on the fan ?
Yeah
Cam does look very dry
Don't fall into the trap I always have. Buy the cer, spend loads getting it perfect then when there is nothing more to do I get bored with it, sell it & start the whole process again with another car.
I fell into that trap many months ago mate haha. I fear there's no getting out of it!
I thought you were going to swap this engine out with your other Audi?
That’s still the plan - but not until later in the year.
Induction heater will get that off, or a reciprocating saw if you want maximum chaos!
PS: Is Bianca single? :P
Cams would be noisy all the time mate and so would broken loose rockers, my money would be on the throttle body closing shut. Sorry I can't be more help.
That's a great help. Didn't really think about that, but must be the case. I'll take a look at the TB and see what I can uncover
Mate I’ve just found your RUclips I love it man keep it up I would just like to ask please when did you get into mechanics? I’ve got major anxiety about it i I didn’t do good in school and got kicked out of college when I was 16 and couldn’t go back when I started mechanics I’m 22 and just started another mechanics course at college you seem to know a lot of just like to know when you started and how old you are now if that’s not to cheeky as I have such a passion about this to I just am bad at learning tbh and I feel like it’s to late
You can see the day when I first got into mechanics by going and watching my first video on the channel lol. Must have been about two years ago. The whole reason I started this channel was because I was fed up with where I was in life and I knew I always wanted to work on cars. So I had this idea that I could start a channel working on cars and teaching myself in my spare time and it might just be able to pay me some money. I knew absolutely zero when I first started. I just bought a cheap car, some cheap tools, and watched loads of RUclips videos of the specific repairs I needed to make.
I tried for years to get apprenticeships, but I'm in my late thirties, so it's much much harder. At your age you've got absolutely nothing to worry about at all. If you give it your absolute all, work like crazy, always challenge yourself, and aim at what's good, you'll get to my age and you'll be in an incredible position. Good luck mate 👍👍
@@NotEconomicallyViable mate thank you for your lovely words and don’t worry your doing amazing your drive and Ambitions is next to none, inspiring. I’ve literally binge watched your channel I’m loving it keep up the good work man and I do tend to forget to click the like button on videos but I will have to go back and check and try to remember to support you! Your funny to mate guess I just need to get past the anxiety of doing stuff j on my drive infront of my neighbours Bevause they all nosey and drama about each other lol wel done starting the channel honestly mate you learn quick and its amazing to watch tbh
wish id watched this earlier I'm in Corby she could have come give me hand changing my x5 engine 🤣🤣
😂
Noise is timing chain
It's a belt
I loved your sisters Salad Fingers quote in there :)
Rusty spoons😂 good oul salad fingers
If the camshafts have pitting on them it means the hardening is breaking up and will only get worse.
This car is turning in to a money pit so unless you intend keeping it and running it in to the ground I would get rid of it now.🤔
Possibly turbo wastegate but they normally would rattle
This dont have wastegate turbo.. vtg turbo
Halo "Brother-in-law"... how you?
I think I would rename the car "Bianca"
Nino she might be a freak.but she a good looking one ❤️ lol
😉
I don't name my cars! after this I might!
I named all my cars, my current car which is my dream car which I will never let go off(Toyota GT86) I named her Krystal after the fox in Star Fox as she is blue.
Love it
So refreshing to see a female that actually knows something about cars, it must be in the genes🤔
Most girls never ever open the bonnet let's be honest 🤣
Use a hammer an chisel for them fans 👍👍
Scrap it my friend
Not a chance
No way ,it’s brilliant.If I work on my Jeep and Jackie starts complaining I say look at what this guy gets up to ,she says wow and leaves me alone.
😂😂😂
I told you about this engines,the worst audi engine 2.5 tdi
