I purchased a 2006 Jetta TDI about 2 months ago. About 2 weeks ago, the car started to accelerate by it's self, then heard this horrible grinding clanking noise and the car was dead. I was driving about 30 mph and the entire event happened in only a few seconds.

I towed it to where I purchased it and they agreed to install a new motor for $2500 and they would take care of the labor.

Last week they called to say they installed the new engine, started it up and within 2 min that engine blew also.

They had checked the turbo and it was fine but found diesel in the oil in both the old and new engine.

Now they want me to purchase another engine, they would install it and then tow to the dealer before starting it. They do not want to be responsible for another blown engine.

However, from my point of view, we tow it to a dealer, they turn it on, it blows and now I'm back to square one but out $5,000 with a non working car.

Does anyone have an idea about reasons for diesel in the oil? Then have now mentioned, fuel pump, injectors, or computer.

Any advice would be appreciated.

Thanks,
Steve

Yes, I replied to your first post when you described the runaway with a link that described why it ranaway. At least a few people mentioned it as well but I will say it again, that thread had a ton of misinformation.

First, your state may have warranties on cars purchased from new and used car dealers. The terms vary by state. $2,500 is actually a pretty good price and they sound like they are doing their best to make you happy. If it comes down to it, have their insurance take care of the engine - that's what it's there for. If it really comes down to it, have your insurance take care of it and have them send the bill to whoever.

Was it a totally new engine or did it have any parts swapped over? They could have swapped over bad parts. In addition, junkyard parts usually have a warranty. If they took care of the labor, the parts warranty goes on the junkyard to get the replacement and they redo the labor. (This assumes the part they got was defective and not something else like install error). If that's the case they take it up with the junkyard.

Diesel in the oil is rare. The fuel injectors are sitting in the cylinder head and exposed to oil. There could be a bad seal at the injector (the fuel rail is built into the cylinder head), a streaming injector, or a cracked head.

Lastly, since you said it ranaway until the engine died, pretty much anything on the old engine is suspect without further inspection. The usual cause is a leaking turbo and they said it was fine which is possible (don't know if they were talking about the old or new one).

It's also possible if they put a new timing belt on the new engine that they screw it up and caused bent the valves.

Where did you purchase it from? A VW dealer or a generic used car lot? Did they check the oil for diesel before they ran it or did this happen after they started it?

This is much more complicated.
- I bought the car "as is" no warranty , no insurance will cover it.
- Yes, $2500 is a great price however now they want me to pay another $2500 with no guarantee. They will put in an third engine and ship it to a 3rd party to test it. I am responsible for whatever they find and if it blows up again, I'm out $5000 and still stuck with no car.
- Yes, they used some parts from the original car
-The junk yard will not honor a warranty as they say some other part of the car caused the damage to the engine.
- The runaway was with the first engine not the second
- They did put a new timing belt in the second engine.

more details needed:

-you described a runaway eng for the first problem, but what EXACTLY happened to the second eng? (if it was also a runaway, you say they checked the turbo, but was the intercooler checked? if a turbo leaks oil, it can end up pooling in the intercooler, which can lead to repeat eng runaways.)

-common sense would dictate that determining the cause of fuel contamination in the eng oil would be the FIRST thing to do, long before replacing the eng. this is especially true if you planned to have a second eng installed, with ANY parts transferred from old to new eng. (im thinking stuck open injector, as one possibility)
speaking as a technician, this should have been done when veh was first towed to the shop - WAS this done?

best of luck.

2nd, what was wrong the first time and what was reused? Before you pay any more, what caused the second engine to fail so fast?
