One of the best diesel engine... Endless list of problems 🙈 Great video👍

[@p__jay]

That goes for all engines! They all have problems and often much more. Everything mentioned in the video is no big deal and normal wear if you ask me…diesel is the best engine we have!

[@minecraft4life525]

It's not that most engines do not have iaaues. It is just how unnecessarily complex and expensive issues are on this. I got my car for 3750EUR. Injectors cost 1500EUR. Timing chains 2000EUR. Right engine mount 350EUR.The small gasket in the v that leaks oil over your accessory belt - 6.5EUR+1 day labour to get to it. Overall 200EUR. We've just done basic maintanance on the engine and looking at a bill of 4050EUR (more than we paid for the car). Ask me how I know these things...

People expect to buy 300k km car and have 0 repairs. These engines are real solid but after dozens of years they require refresh of alot of car parts...

[@minecraft4life525]

@@makerudji6682 I don't really expect anything different than I do from my 600k 1.8 Audi A3 8l or my 390k 2.5 T5 Volvo. For the 200k total km I've put on them, they have together costed me less than the 40k km I've done on my a6 c6 3.0TDI. For the record, the Volvo is both more comfortable and has more features than the Audi, which is for sale if anybody is interested :D

[@1980yazo]

My 2005 A4 B7 BKN with software on 250 hp now runs perfectly with 410,000 km (!!). At 250 thousand I changed injectors but that was the only investment ever on the engine (!) still 1. timing chain, 1. turbocharger 1. high-pressure pump .... otherwise nothing ever happened!! I hope to get over 500,000 km without any problems and will do it every 10 thousand. Oil change ;) oh of course the ZF 6-speed automatic transmission is also the first! Truly the best car I've ever had!!

[@benturp3492]

300 000 km on my 2007 A6 3.0 tdi. Had a ticking noise and it was injector leak. new washers and its fine again. Great engine. Everyone seems to be hating on Audis but i think they are great cars!

[@Danis73]

People are saying "ohh it's ticking bomb, ohh it got a lot of problems" when in reality its pretty realiable engine, like a lot of diesel engines turbo, injectors, egr, dpf, is common issues and its not a big of a deal, turbo and injectors can be restored, you dont need new oem ones, dpf and egr in my opinion should be deleted, then you bypass that mysterious coolant leakes cuz of blanked of egr, and you dont suffer from cloged dpf and turbo problems, you pass all mot inspections co2 tests and evrything without them, swirl flaps are not a problem but you can delete them to. The biggest thing is the timing chain in my country it does cost 1200€ with the labour and parts. So i have this engine (audi a6 c6 3.0tdi v6 quattro automatic) and i love this car, before i had m57 bmw, same thing that can occur turbo injectors ect... So dont be scared of a good engine, ofc if u want to go on a cheap side just pick 1.9tdi and thats fine.

[@davidbillyard6629]

That’s good advice.

[@what9418]

I spent 7k euros on mine. Leaking water and oil, sensors, swirl flaps, dpf, egr thermostat. But it was a great car, 2007 A5. Swapped it for a SQ5 in 2017 which I still own.

[@hamsterdangler]

I have had my 2006 A6 Allroad for 13 years with 310.000km, wonderful car especially with the manual gearbox, heard a lot of problems with the auto box, ASB engine with the original diesel pump. Years ago replaced turbo, and injectors, it now needs injectors again, thought it was getting a bit old and bought a BMW. Chalk and cheese, now going to sell the BMW and keep the Audi.

[@hamsterdangler]

My wife has a 2006 A4 3.0 tdi s-line quattro cabriolet, same ASB engine as my car, still with the manual gearbox, terrific car, always better than 40mpg.

[@erwyyn]

I'm thinking on buying one of those. Do you recommend the c6 or the c5 model?

[@hamsterdangler]

@@erwyyn I would suggest a C6, but then that is one that I know, I did have an A6 2.5tdi before but not Allroad. It seems that the best ones are like mine, late 2006 or early 2007, before they changed to the Bosch injector pump which had issues. But at that age you do not know how they have been treated, I do oil changes every 15,000 km, I suspect not many do, expensive oil, and a lot of it. I suggest that if you buy one it may be useful to get VCDS.

I have a november 2007 A5 coupe with this engine, have it a year now, absolutely love it. It has 123,000 miles on it, clean car, still feels tight. Pulls well for 240 hp but thinking about having it mapped, I hear a stage 1 tune can unlock about 60 more hp and more torque. 😁

[@mnnaqs]

Have a 09 Touareg same engine 225 bhp stage one this week popping on will be 275 bhp with 75 nm extra

[@skelbagz]

I had the sticky intake manifold issue on my CAPA engine. It's a pretty cheap fix but you need to get it sorted as soon as you can as if an error is detected they apparently default to wide open which can result in the air/fuel mix getting messed up. Otherwise I think it's a great engine.

My 2011 touareg injectors were putting pressure into the leak off pipes too, also the large plastic coolant item that bolts to the front cover and connects to the egr is prone to failure on high km models too, also you should mention dirty intake systems causing issues, RUN A CATCH CAN ALWAYS! injectors fail usually before 200 on 2nd gen tdi engines with piezo injectors, also coolant shut off valve is prone to failure on 2nd gen engines

True for coolant shut off valve, i had this problem

Never install a catch can, unless you live in a country with no winters. Otherwise, the water in teh catch can will freeze, the PCV system will be blocked, and pressure will build up inside the engine causing damage to the seals or worse.

[@theriverthatflows98]

OM648 and even the OM642 are much more reliable than most of the TDI's in Audi/VW cars, especially the crappy 2nd gen 3.0 TDIs. For example, both the 648 and 642 use a duplex timing chain, whereas the TDI's use single chains, thus having much weaker resistance to streching and I'm not even talking about the more complex chain system of the TDIs. Furthermore, to change the chains, with both the OM648 and 642, you don't have to take out the engine + gearbox from the car. The 3.0 TDIs, both the 1st and 2nd gen, require the engine and gearbox to be taken out to service the chains (if I remember correctly, you can only change the top right tensioner in the TDIs, which is also a very common problem with the TDIs). The Mercedes is much more DIY friendly (sounds ironic, as Merc doesn't have this reputation after their legendary W124 era of unbreakable and easy to fix cars). The only major problem of the Merc engines (mostly the 642, not the 648) is the oil cooler gasket, which starts to leak at some point of the engine's life. It's a very cheap part but it requires quite a few hours of labour, but if you do it yourself - it's dirt cheap, the gasket is something like 15-20 euros from the Mercedes dealership. The injectors are the only place where these engines have similiar reliability, the Mercedes OM648 suffers from the injector o-ring problem (called the black death in the Merc community) but it's very easily and cheaply fixed, if it's not left abandoned for too long and a layer of black tar has not eaten up the injectors. Personally, I feel a lot of regret going from the OM642 to a 2nd gen 3.0 TDI. The merc engine, at 319k KM mileage hadn't had any major problems, apart from the alternator belt and all the pulleys needing to be replaced (a job costing around 300 euros, lasts a long time) and just the timely oil/filter changes. On other hand, my recently bought A5 with the 2d gen TDI, at 209k KM, is already having chain rattles at warm starts, which is very confusing, as I have always regarded the TDIs as reliable and well built engines. Maybe that was just a legacy of the mythical 1.9TDI, who knows...
