Volkswagen dieselgate cars where sold off in various venues by Volkswagen.
we never actually got a copy of the government mandated warranty on ours. We purchased it through a used car dealer that had an ex Volkswagen service advisor on staff. He told us what he thought the warranty was. I found out later it was two years longer than he mentioned.

Many where just sold through car auctions with no mention of the warranty. I kind of watched. Sure enough one turned up cheap with problems at a Dodge dealer as a trade in.

I called them. They told me their back shop could not deal with the problems. I asked them the millage and I already knew the year from their ad.

They did not know it was still under heavy warranty. I did not enlightened them. I suspect this situation will happen over and over again around north America. My guess is most of them have been subject to too much city driving. I did not take that one myself. If we were not on the verge of retiring from an income stream I might have. Fully loaded highline Passat.

First I would have had to drive there. Take it to A Volkswagen dealer to see if they could check it out. Would have had to get an appointment. From their description of the issues all would have been covered I suspected. This situation is more common than one would think. I have run across a few owners myself that did not know their car was still under Volkswagens dieselgate warranty.

I suspect this situation does not apply to Mercedes dieselgate cars. As there was too much correspondance with owners. I cannot remember even if Mercedes purchased them back from owners. Most the Volkswagens where buybacks with the company. We have rattled ours up to 100K miles in the past about two and a half years.

Two problems so far. Urea injector and exhaust restriction valve.Covered totally with no isues. Warranty still extends to the end of September next year if we do not put too many more miles on it.

First official inspection for retained soot in the soot particle container is at 120K. Naturally the warranty stops at 119K. You have to love these companies. I will have that checked at 118K without fail. Although with basically only highway miles it does not seem to be a problem. You plan of using these cars in primarily city driving they will cost you after the warranty.

Anyone that owns one of these type of diesels. Be it Volkswagon or Mercedes. Do your oil changes really early. When these engines start to consume base engine oil. I suspect without really knowing it will cause havoc in their pollution control system, At 100K miles ours does not appear to be using any base oil between changes. Just judging by the dipstick reading.

I also suspect again without knowing. Both Mercedes and Volkswagon are using very similar automatic transmissions. Volkswagen went from lifetime fill. As there is no dipstick. To change the transmission filter and oil every forty thousand miles. Up to the owner of course. Me paying Volkswagen to do an engine and automatic transmission oil change is around five hundred. Doing it myself being careful to follow the instructions. About half that cost.

I cannot find the ESP engine oil locally in 10-30 grade. I can find 5-20 mobile esp that is allowed. As is the 10-30 esp. Do not have the dealer change the engine oil unless you see what they are putting in. Volkswagon in Canada is putting in 0-20 esp I found out.

Transmission gets into 6th gear fast. It will hold it down to about !K revolutions. The engine revs are only 1200 at fifty miles per hour. That to me at least is loading the engine to some degree but basically unavoidable if you want the fuel millage these are capable of. Since diesel engines burn almost nothing at idle. You can average about 48 miles per American gallon in city driving.

Diesel fuel burns slower than gasoline. So the advantage of operating at 1200 rpms or less is more energy efficency. You are not losing the pistons moving away as quickly. So more work gets performed for the same amount of fuel. This seems to make up for all the stopping, Waiting at lights and almost constant speed changes. Things like fuel injectors are not rebuildable to my knowledge. So expensive like a lot of things on these more modern diesel engines. They will probably not make economical really high millage cars. Many of these Passats where built on the audi a4 production line. So there are a lot of simularities.

This year is the last year they are being produced. That assembly line fell below Volkswagons paint finishing quality unfortunatly. Generally quality of assembly was better than the Mexican plant though. Never any detail issues so far. Since the same car was also built in China. I almost have to assume a huge amount of the car is composed of Chinese made parts. The European built Passat is a different car. Never exported to north America to my knowledge.

I had a 2012 VW TDI bought used just before the cutoff date where they wouldn't have had to buy it back. I kept increasing the mileage and time on their return calculator and the buy back price didn't go down. I ended up driving that car essentially trouble free for years and sold it back for more than I paid for it. Would definitely make that deal again.

On the Bluetec recall you get an extended warranty see here

It looked like I was entitled to a substantial payment from mb on my 2015 250ml. Mb buried me with about 20 sheets of small print legaleze. I eventually gave up on it because I suspected if I did all that paperwork I'd not get anything at the end. It makes me afraid to buy any modern mb. Give me a 123 or 124 though.

Volkswagon was far more clear on their extended warranty I think. Plus payouts of various types to owners.

I found another 2012 Volkswagen Passat diesel with 40 thousand miles on it. The lady inherited it from her brother apparently. She thinks the warranty is over. I am not that sure as ours is not with a lot more millage.

Personally and it is only an opinion. Get them cheap enough and before too much millage is built up sell them. Use primarily on the highways. I think when the warranty is gone in a little more than one year from now. So is ours. Far too many potential expensive issues with them exist. I think the high pressure fuel pump is alloy. If they shred metal. Think well over five thousand to replace the bulk of the fuel system. I may pre empt change that high pressure pump at the first timing belt change. A few hundred dollars I think.

Anybody that feels complacent about these diesels be it Mercedes or Volkswagen. Should remember why they cheated. They were seeing too many carbon buildup issues under original warranties before they cheated.

After the fix the egr is working normally full time again. Also there are some parts that have had multiple updates to improve their reliability. That to me indicated the original ones will be failure prone. Cost of particle filters for replacement are almost a scam. The bad ones go back to China for a rebuild.

I can buy the internal cartridge or I should say could from china for 15.00. You cannot get a really new particle filter assembly. They are all rebuilds. That part would be no great deal if it was sold at a reasonable profit.

I also do not know about the later Mercedes diesels. The Volkswagen diesel is pretty cramped in the engine compartment to work on. Performance of both diesel brands is good. The potential to become serious money pits is also there.

I have a bit of VW diesel experience...

I owned a 2011 sportwagen tdi with the 6speed manual. I removed the DPF at 120k when the factory warranty expired and drove it without issue for another 60k. It was a great car and I would still have it I'm sure but VW offered me a buyback price that was unbelievable.

The other weekend I replaced a turbo on a '12 TDI Passat with around 130k. Somehow the impeller shaft sheered in half. This was about a 10h job. Subframe is lowered a bit and the DPF is removed for this job. There's a bunch of other emissions related stuff in the way that makes it a pain.

My wife drives a '12 Touareg TDI with the V6 diesel. We've put 60k on it and its been a great vehicle. The adblue (DEF) thing is annoying.

With VCDS (star/xentry for VW) you can check the ash content of the dpf to get an idea of what the remaining lifetime is. VW specifies a specific oil in the TDIs to reduce ash buildup in the DPF.

On the emissions thing...How can mining and refining the minerals and raw materials that go into the DPF and manufacturing the product, then manufacturing the DEF fluid and plastic containers it comes in along with the whole supply chain process for importing that from China on a cargo ship which has no emissions standards all be better than simply operating without all that apparatus on the vehicle? Then when the part is at the end of its lifespan we replace it for over $1000, or better yet scrap the whole car and start over.
