- Welcome to another video.
This time we had this Audi Q7 with a 3.0TDI CRT engine booked in just for timing chain replacement as prevention. Car was behaving normally on roads and also there were no fault codes in the diagnostic. We proceed to work as usual so engine out. We inspected everything at the same time and we did find loads of carbon in the intake. Owner agreed to proceed with the extra work and once we were putting everything back together we found this ....Thanks for watching , if you want to know what's going on daily at our workshop you can follow us on instagram !

And this is why I’m still running a 27 year old C4 A6. It’s now on 355k and the engine has never been apart. Will still go between 6k oil changes without topping up too.
Making machines durable is a way of “saving the polar bears” that seems to have been forgotten.
C4 are tanks. What engine ?
I thought my 1996 Volvo 850 2.5 GLT was high mileage at 237k miles, bloody hell..
Ha, me too - I have a 1996 C4 A6 2.5tdi. Owned since 1999, I'm the second owner. It has 300k now, the only major component to ever be replaced on the engine was the fuel pump, at around 270k. I also have a 2020 SQ7 Tdi, and I'm glad I doubled the oil changes from new.
@@highlandmalt6368 Smart man. And those factory 0w30 oils are a no go. Also recomended is to raise the variable oil pressure to 2+bar by an oil map remap. So many cars die too soon because of essentialy oil starvation and premature wear. For what You may ask? 3-6% ( at best ) lower fuel consumption. 😔
My C4 A6 was delivered 18. Nov. 1994 with 140 hp 2.5 TDI 5-cylinder. It was one of the first 140 hp engines delivered as they started delivery at 1. Nov. 1994. At 75k kilometers I went to ABT and they did 160 hp on it. At 335k Kilometers I only changed the clutch, cause I had a lot of heavy trailer transports with it (there where marbles and tiles on the trailor mostly up to 2 tons often more) and it was a 6-gear manual gearbox. It was the most awesome car, I did only service all 15k kilometers which was likely all 8 weeks. NO repairs otherwise…. It just run. I gave it to my father at 335k and he drove it up to 500k then the engine broke, cause he missed to change the crankshaft bearing, which I told him to do. The change would have been easy and low cost, but anyway, that was the most awesome car. It was with full options and runs between 4.6 to 7.5 liters/100 km. But 7.5 only full throttle on german autobahn, which means up to 240 km/h
Where is that green engineering now? What are the improvements? Bad working technics can‘t save the planet or polar bears and I can‘t see the better efficiency to that 1994 car…
Got to greatly admire your skill, professionalism and honesty not to mention your nerves of steel to tackle such an expensive repair with such sketchy "technical information" from Audi. No used Audi's for me thanks for the videos.
I have owned some Audis, and I appreciate your channel, I won't own an audi out or warranty anymore but I applaud your expertise and tenacity to make them right for customers and as entertainment for your viewers
There are some good models. My experience of the A6 C7 2.0tdi Ultras has been fantastic. Had two and they've been bulletproof for years and hundreds of thousands of miles (with non-variable servicing). CNHA engine 190hp.
I wouldn't recommend anyone buys any newish Audi with more than 40k miles on after watching this channel.
They seem like throwaway engines these days........dreadful.
I wouldn't buy an Audi FULLSTOP.⚠️
@julesviolin ya and all the losers on ford repair channels will never own a ford,and all the people on BMW repair channels will never own a BMW, and all the people on Toyota and Honda repair channels will never buy a Honda or Toyota again. Give me a break, all you snobs are so clever now that you discovered youtube
royalblood2405 I totally agree.I can’t believe how so many people trash everything on the road. I am close to 70 have driven them all.Drive like you care do the maintenance and you will be good to go.
I had an Audi a5 3.0 tdi v6 CAPA and had no issues besides swirl flaps wearing out at 140k. Sold it a year later :) Think others can get chain issues but I had no issues with chains.
I bought my last Audi 20 years ago, a 1990 Audi 80 with the solid 1.8 engine running on petrol and LPG.
In those days Audis were solid cars that could last half a million kilometers on LPG without engine failure or manual valve adjustment ( engines had self adjusting valves). Today, the Audi's look good buy you need 'Audi money' to keep it on the road.
Better to do not buy ANY NEW CARS!!!!
@@mihai-danut6955 No, I think I will stick to old Toyotas since I bought a 2nd gen Prius 5 years ago.🙂
You’ll also need a spare car to get you going when Audi is in a shop.
I’ve got a 2014 w/125K miles, no issues and no rattles but wow this one is an eye opener for 3rd gen engines. Great video
Considering that the second gen is way worse than the third gen, you are just lucky.
Idiot@@peterbratu
worse how?@@peterbratu
Excellent video guys. What a way to design an engine. It seems all the good practices learnt over the years has gone out the window, in the guise of emission statistics 🙄
Unfortunately
If I was a conspiracy theorist, I might suggest built-in obsolescence!😳 But that would mean Audi doesn't really care about the polar bears and I can't comprehend that...😢
Dead elderly polar bears are an excuse to F over the world. Sea levels are not rising and CO2 is now enough keep the vegetation alive. Thanks to us burning oil.
@@toeknee2u it's called the design life of a component, it would not make sense to test above a certain mileage/age so they make the cars with this sort of minimal lifetime... the funny thing is that the design life of say the old VE pump TDIs was probably less than what it is for these new engines, it's just that the simulation softwares (and computation capacity) have become much more accurate and widely available. So above this mileage anything can fail and the manufacturer doesn't really know what and when will likely happen. Nothing is designed to break! There's just a minimum it has to last.
@@petermolnar8667 Didn't I say that..... in fewer words?
I love watching your channel and the rebuilds you do....I still find it amazing how much carbon builds up in the Audi engines...given today's technology with fuel and oils and dealer servicing the amount of carbon is unreal...I used to overhaul old heavy duty diesel engines on earth moving equipment that had done thousands of hours running and cannot remember ever seeing one with so much carbon builds up as you are showing us..thanks for sharing you quality workmanship and dedication to doing the job right..👍👍
Carbon build up has nothing to do with servicing. The issue is that todays technology if forced to find ways to reduce emissions at the same time as improving economy. Direct injection petrol engines that don't clean the inlet of deposits from ventilated crankcase gases, exhaust gas recirculation etc.
You guys take pride in what you do. It is refreshing to see a knowledgeable mechanic who does a decent job.
Great video - huge skill and professionalism evident. I ran Audis for 20 yrs (all S8's) but watching your videos I wont be doing so again... Great to see a preventative maintenance approach (like an airplane) here but the economics are surely questionable i.e. almost £10k spent on a car worth trade in of £25 - 27k? What is next to fail? Probably suspension pumps etc? Terrible engineering compromises to meet so called green targets; how many of these cars will end up in scrap yards at 10 - 12 yrs old as no one will be able to afford to maintain them. (Look at the recent SH values of decade old Range Rovers / Discoverys etc to see this). Finally, its the first time I heard of oil pressure remaps - very interesting / useful.
100% all these cars are going to be scrapped around the 10-12 year mark. Such a waste.
£13k was spent
Just not worth itl.
Yes, it's totally bonkers..making a car with more green credentials to only end up as landfill as the expensive is just ridiculous for the market value of the product..everyone knows that most new German cars are very very good, once they get a few years and miles on them they are very very bad..
I can remember when the biggest headache you’d have in a car was the automatic choke would stick 😂 and your points would wear out
I find you videos absolutely brilliant your repairs give so much detail. Unfortunately after watching them I would not recommend an Audi to anyone that showed an interest in purchasing one. My first move would be to guide them to your channel to make them aware of possible faults. All the best to you all in the future and keep the videos coming.
sooooo go for n57 or n47 be am dabalju
Thanks you for your patience and for all the thoughts. Very useful
Happy New Year chaps. Thanks for the very interesting repair jobs over the last 12 months.
Agreed. I have a 1.2tsi with oil changes every 8000 miles. The timing chain is still perfect and engine clean inside after 130k miles. Direct injection and long oil intervals means soot in the oil causing wear on tight clearance items like chains.
100% agreed. So true with these modern generation engines.
Just glad I have an older Audi 1999 a6 4.2 40V last of the great engines!!!!!!! Happy new year to all🇬🇧
Great video, thanks for sharing in such detail. The thought of owning one of these out of warranty fills me with dread tbh
I'm new to the channel and appreciate seeing some real work done as apposed to the usual someone changing brake pads. Please no brake jobs.
So the next video won’t be for you 😀
Brilliant video. Great attention to detail and not accepting the Audi manual fitting instructions without applying proper engineering principles.
Top job
great informative video thank you. The timing chain will supply and fling plenty of oil to the cam gears etc. My approach with these V6 VW diesels has been to 1/2 the service internal for the oil and filter changes. Also reprogram the start/stop functionality to default off instead of on. Pretty much all of your issues will go away. I change oil at 7-8,00 kms max. They are an incredibly durable, efficient and powerful engine. Unfortunately many people run well over their service intervals (even with new cars) something you just can't do with these engines.
Happy new year!!!🎉
Nice view about audi engineering and engine fault. How I see, it is not only audi engine problems, this problem with world car manufacturers, because the cars make ecological (friendly).
Good to see you guys back.
Fascinating technical content in this video. Thank you.
Happy New Year guys. thank you for your videos :)
Could watch your videos all day .very clever
Brilliant job and excellent explanations, thanks 👍🏼
It's mad to think Audi and VW used to be the cars to buy for reliability and bullet proof engine's.
My 2005 passat TDI 200k miles ended up in Cyprus and is still working fine.
What the hell happened.
Love the channel just feel sorry for the everyday people who buy these cars.
Keep up the good work 👍👍
It’s the regulation making them approve silly things like this … we are talking about efficiency of 0.3% if but according to EU nonsense it’s enough to save the polar bears
@@VAGTechnic I'd like to see the comparison with a older TDI engine to a newer version on the emissions side.
Most of my old VW used to average 50mpg easily.
And I have a heavy right foot so if you drove them like a old lady much higher.
But surely all these problems will eventually become a massive problem.
Or maybe all in master plan to convert people to electric cars.
People who buy these cars usually ditch them once warranty expires. Buy at your own risk beyond this
I think you are on to something. Here in Germany they are taxing the diesel engines heavily even though they get better mileage with less CO2. I think VAG made reasonable diesels but the emissions stuff makes diesels very hard to engineer. The voters keep voting the same clowns in.....what do we expect?
prevention is always better than cure...hope you had a good xmas and wishing everyone an abundant wealthy and healthy leap year...great work as always, and I need to have an oil change and also the timing chain done on my S4...I'm sure there will be other things, given its done over 108k and is a 2014 B8 facelift
25:42 Dobre! :) Amazing work guys. Thank you for the detailed design review.
Nice work, good job!
I've had a Porsche Cayenne 2009 first gen facelift, 3.0 V6 TDI bought from new and sold it at 330 000 km (about 206 000 miles). Oil service every 15 000 km, never had any issues.
I have now a 2011 Phaeton 3.0 V6 TDI (I think the same engine) 60 000 miles ( about 100 000 km). Car seems perfect now (had it for 9 months), will see how it goes from now.
Cheers!
Very in depth video guys, and you have put me off buying a vag 3.0tdi car lol . Engine is made to fail from how you have described rebuilding top end .
Another excellent technical video, thanks
you guys are the lick i have a s4 b9 78000 full Audi service history and i think i will be spending some big money with you soon. I Love your vlogs
What the actual F??? Planned obsolescence? That intake carbon makes a DI engine look like child’s play. I seriously can’t see why this was allowed to pass a quality control check for durability and longevity. Mad props to the shop for putting this info out. Seems like a good way to create an excuse to stop selling TDI models. I think I’ll stick to my 4.0T.
Love your honesty. The Good, The Bad, & the Ugly. Awesome video and company..I hope the designers of these engines watch this.
Oh this is gonna be a good video, doggo mechanic is already running around the workshop in the first minute and probably heading for the phone to order a huge amount of parts from TPS
Starting off 2024 with a VAG Technic video !!!
I think i stay with the 2 liter tdi. The 3 liter V6 tdi is my dream and has to stay my dream with this information.
Audi know about this but won’t admit there is an issue. I had the exact same problem on a 2016 allroad with the 272PS unit. Warranty didn’t want to know nor would they share the part numbers or the changes to the parts.
Car had approx 52k miles on when the chains started to rattle. The sprockets on the camshafts were more worn than the one on this Q7 so it’s done well considering the mileage
Nice work. Like watching you videos. 💪
You really need to make VAG Technic shirts that say "MYSTICAL & MAGICAL" !!
An alternate idea I heard them mention: BBC ( Big Bill Coming )….
Thx, for making people aware of the pain of these variable oil pumps another not very effective fuel saving system that destroys engines.
I hate the BS of extended service intervals + low tension oil rings on newer engines.
Like is it really a clean engine when you have to tear it apart at 150.000-200.000 km, just to saving single digits reduction Co2 emission.
I 100% support cleaner engines but the balance between emissions and longevity for sure took a wrong turn.
Very impressive stuff you are doing there and with a very good taste of humor! I am driving the 2019 A6 C8 50Tdi with DDVB engine and I am wondering if that engine has the same issues regarding carbon build up and oil pressure? What's your experience and advice here, it now has 155t kms on the clock and so far had only a faulty NOX sensor! Planning to do the ZF oil exchange every 60tkm after the first done at 120t km.
Yes it has the same problems
Hope you are feeling better now, great new video.🏴🏴👍👍
I have been driving Audi for over 25 years and every new car I had, had more problems then the one before. The Running costs of Audi are insane and with pain I will move to another brand of cars.
all vag cars are over engineered shite and all rust away to dust. i wouldn't have one for free let alone pay for one.
only buy this junk new and sell before the warranty expires
Happy new year to you and your team ,,, another great video again,, glad you are busy, wont be buying one of these cars take care 😁😁
man ur super precise....i feel like my 2-5 tdi is a lottery ticket compare to this....love your work...because of you i dared to buy non working engine old allroad, fuel pump problem and some suspenssion arms....only because of your videos iv seen before and internet in global...my father is mechanic, but never done so modern stuff, yapp, 2.5 is space shipengine for hem, specialy the rest of allroad.....all the best in upcoming years, audi should pay you million dollar a year just cause your talking and recording while wrenching
I feel like VW is going to send a hitman on him before that. 😅
nice to c u back again been missing the videos .
Thanks for this great video on demystifying VAGs engine strategy. After swapping from a A6 4F with no problem at all I am now confronted with metal cuttings in my 2-year old Q7 50TDI mild-Hybrid (DHXA).
Would you be able to specifiy your optimized oil pressure specs again so I can use them as well? Kind regards!
Outstanding video! Informative and well done. Subscribed for more.
Great job guys 👍
The later oil pumps have different specifications higher mid and upper range pressure, so I recommend changing the pump while the engine is out. Regards, Dave London
And all this because of exhaust emissions 😂, love you videos.
I've been awaiting your new video. I hope you and Miri had a quiet Christmas and New Year.
Keep up the good work.
Could you add oil spray nozzles pointing directly onto the cam gears, like they add lower piston spray nozzles on older performance engines?
Was sick , but back now again 🍾
On smaller Vw cars like 1.6 - 1.9 tdi what would you reckon how often would you change the oil, great video really clear & easy to understand 👍☘️🇮🇪
Hey guys! Great video! Which engines are affected of the camshaft problems? Also newer 2020 Audi's? Which would be the best 3.0 tdi engine paired with zf 8 speed? I see that A6 biturbo 313 and 326 has a different setup? How about A4 B9?
👍 .You can try in future with diferential preload paste (color) set up the preload without rockers and lifters and play little bit with small torque wrench and find a sweet spot where marks on gears would be nice and even surfices and than preload gears and screw all setup 🤣.Good video keep them comming!
Nice job and great video
You, Sir, are a rare thing these days. A genuine mechanic and engineer, who thoughtfully diagnoses issues without simply throwing a parts cannon at fault codes. Fantastic explanation. This not being covered under warranty is disgusting when it is failure by design.
When pathetic increases in efficiency are achieved by bad engineering that literally causes a whole car to fail and so costly it is not worth fixing, then the Polar Bears are surely doomed.
I'm proud to drive a 25 year old 5.7l V8 LandCruiser that still runs like new, that by virtue of running forever, is actually the true saviour of the Polar Bears, as others will have bought 5+ "eco friendly" new cars in the same lifetime that this has simply drank a bit more fuel.
Please tell me what's worse for the planet. An old (relatively) simple engine drinking a few more gallons, or making a whole brand new car from scratch every few years.
What a massive con our governments and the big manufacturers are selling us.
I'd like to see VW run that famous "if only everything in life was as reliable as a Volkswagen" ad campaign now and see the public reaction.
Superb information guys. Is this engine the same on my 2015 A8 3 litre tdi sport executive?
Audi need this man to make the ultimate engine
1.9TDI is coming back guys 😂
@@VAGTechnic😂
@@VAGTechnic😂 it was in our hearts all this time 😂
Nice work. On referencing your own adjustments .🍺
Impressive engineering skills! 👍
Do you know if the oil pressure issue also affects newer DEW code 3.0 TDI engines used in B9 S4/ C8 S6+S7?
Hi , a very informative video. I have a 2019 SQ5 TDi , would my engine be subject to the same build issues as you have shown with the Q7 ? I know some parts are different but I would appreciate your thoughts. Peter
Interesting video! I’m driving an A6 with the same engine. Mine broke down at the crank bearings due to the lack off oil pressure… only 70000 miles
My condolences to all Audi owners.
I have similar problem same engine what did you do to get it repaired?
did you repair the original or fit a new engine?
Thanks for the video and good advice,was looking at 2015 audi a6 3.0 tdi,i need your advice,are they same engine?as iam going for a testdrive on friday
Awesome Video, do you have any idea if the 958.2 Cayenne Diesel (2016 USDM, I think is CNRB engine) suffer from the same issues? Do you know if the 2016 North American models come with the updated camshaft parts? I have not measured timing stretch yet but want to plan for preventative maintenance
Brilliant channel ! Subscribed. 2 Things, I am based in South Africa and could have those gears pressed off and cut new and and cams and new gear nitrate hardened for a quarter of the price. Also sometimes one must not over react . Hydraulic lifters are not that serious . I have seen them last 700 000 km ,yes you lose a little performance , but no serious failure issues 😉😉
I do my oil changes every 10,000 KM and the oil and filter costs about $120.00 AUD fully synthetic because of the EGR and DPF which is needed to save a dolphin. 20 minutes work gives me peace of mind knowing that I wont have that nightmare happening to me.Australians love Toyotas and thats why.
Good job again !
I have a question about the crankcase ventilation ... as you know now on the C7 it is built into the head covers and a bit expensive to replace but it is very important with the increased crankcase pressure after a remap or increasing oil pressure like now ... do you have any solution such as putting an extra membrane , external oil trap and etc ?
Bring it on, because i honestly can’t wait 😢😊
Bravo braćo! Pozdrav od vozaca Tesle :)
Awesome video. Thanks 🙌🙌😊👍👌🙏
Another good video..👍👍
Have you ever considered using stanadyne performance formula I. Your fuel? It is a cetane improver which modifies the combustion characteristics of the fuel. Possibly reducing carbon as fuel combusts more completely. Recommended by Volkswagen
Great walkthrough. Do you know if the 4.0TT also has this oil pressure mapping, and if so if a re map would be beneficial?
Definitely, you can check it with diagnostic
Woah that carbon buildup is insane!
Gday fellas I have been a fan of Audis over the years but now I wouldn’t even contemplate these nightmares I feel for you regarding the super manuals intructions
Very good job 👏👏
I would like to do the remap to the oil pressure hear in Spain but I don't know anybody who can do that😢
Great work guys , just as well the customer has deep pockets , my self will run our A4 tdi until the dinosaur diesel runs out .
Great video and another reason why not to buy an Audi with a 3.0 tdi engine.
Now I know new Audis had troubles with newer engines but seeing this tear down I am totally shocked what the hell are they doing I would never buy one!
Great Video Tom, you will be kept busy by the VW design engineers bad news for the owner's doe😒
Move these V6s on at 80k would be my thought. The chances of just a timing chain swap being all thats required look slim. These V6 /8 engines are really pretty poor from VAG it seems. Good workmanship by you guys as always.
I bought a 2012 A6 fully loaded with the 3.0 TDI for cheap.. it has a 0.5-1 sec startup rattle sometimes, and ill just live with it.. Great winter car, dissapointing to see VAG still only put out 3.0 TDIs with timing chain issues.. but i love watching your videos.
VAG = timing chain noises or issues
i have the exact same, 2012 A6 fully loaded on startup just a small rattle that disappears quickly. it's done it for years
just got rid of it haha dual mass flywheel and a prop shaft went and got quoted 4k for it to be done
Guys, did you ever heard to bring hydrogen into the intake to prvent all that carbon on intake parts? From what I read and saw, the hypdrogen is burning down that carbon completely so that even the particelfilter keeps clean. Maybe this would be the better way to engenieer green engines than with the egr-system. I will try it on my own 3.0 TDI A6. It‘s an ASB engine from 2007. Thanks for that hint with the oilpressure mapping, I will ask my guy who did also the engine mapping on 300hp if he can adjust the oilpressure mapping too. And I let you know the results of the non egr and particelfilter plus intake hydrogen system.
Many thanks 🙏 for your awesome work and sharing your knowledge
Great content as ever 👍
I can watch this channel for hours..
Very informative as well.
I’ll never buy an Audi TDi now 😕
I just wish there was a Ford Tdci specialist in the South..
Great video!! Good to be aware of how warranty jobs get done half-assed.
Should we save polar bears, or make engines that last and are easy, less costly to service and maintain?
Keep the vids coming!
Luv ya work!
Cheers from down under.
Very talented 👌
Good stuf, finally English again!! Yeah, best wishes for 24!
Hi, I really enjoy watching your very informative and interesting videos.
I think this situation goes back to what you were saying about the tell tale signs of tarnish and staining within the engine and obvious lack of oil changes.
diesel oil can degrade and become sludgy if not changed regularly leading to poor circulation which is crucial with this engine design, seemingly relying on oil to gravity seep down and lubricant all the moving parts 😮 with the added problem of lower oil pressure not delivering enough, quickly to the top of the engine..
I watch a video, basically the oil was change 5 times and engine run each time before the oil actually came out of the sump clean😮 apparently he said a person didn't believe the oil was changed when their car was serviced, its because they didn't realise the oil turns black as soon as you start the engine.
It would be ridiculous and expensive to flush oil 5 times
I would say and engine oil flush addertive with the old oil then mabe 1 extra oil change should be sufficient but it just proves how dirty the internals of an engines can become with higher mileage especially with the lack of oil changes which is Crucial for the longevity of an engine..
Hopes this information helps 😊👍
I saw that video too! 👍
The diesel engine oil looks blackish immediately after an oil and filter change because up to 10% of the old oil does not drain out of the engine. It stays in the oil galleries, the oil pump and also remains as coating all the engine surfaces. This is perfectly normal and happens to every engine. Maybe the 3.0L V6 would be ok if 5k - 10k mile oil intervals were applied, not the crazy 20000 mile long life intervals.
@@jimb7406 yep lack of oul changes is precisely what causes carbon deposits and sludge build up over time hence a flush would help with with fresh oil run through then another refill with the new filter.
this is only pennies compared to a ruined engine that needs rebuilding or replacing because of sheer ignorance of regular maintenance which is crucial with the longevity of a diesel engine!
Hi, can u explain how to clean the carbon during oil changes?
And this is why I now drive a Toyota after several try’s with VW and Audi. To be honoust, my Mercedes C220d wasn’t free of issues as well and a colleague with a Volvo V60 also has many issues. So I’m done sponsoring so called ‘premium’ brands and just bought a new RAV4. Of course, different in every way, shape and form, but so far I absolutely love driving without a care in the world. Great car!
my A6 TDI has 280.000km now...never had a problem with it 🤷🏻♂
@@p__jay Which of course is great and I hope you will add many more km’s. They can’t all be bad 👍 I wasn’t that fortunate with my VW Passat and Audi A4 (both bought new) so I will pass for a while. We’ll see in the future.
Hi. For this engine would you recommend for preventative and maintenance any oil stop treatment added to the oil?
Can you please suggest if CZVA 160kW from A6 is also affected?
My 2012 A6 Allroad biTDi just blew out all its oil the other day via the oil pressure relief valve, only 101k on it too. Caused oil starvation and now has shards of metal in the filter. Do you think its worth rebuilding a known engine with full service history or getting a second hand one? Love the car and it took me a long time to find the spec I wanted. Only had it 5 months, so waiting for the dealer to see what resolution they offer first.
Wow really enjoyed this video so interesting to hear why they go wrong and so glad I own a lexus and not audi 😁
HI, Do you offer inlet cleaning for Audi Q7 50 TDI? If so - any idea on the cost and timing? Many thanks
This is the exact issue that I had on my 89.000km A6 allroad 3.0 TDI 2015
That RS4 B7 looks great tho
I like the engine in my A6 it's a pd 130 bit noisy but a solid engine. How many kilometres had the engine done? It's a shame you can't replace it with a timing belt or quad chains.The gears don't look wide enough no wonder they are worn out
