Need help getting 2004 Touareg v10 back into running shape

I'd like to poll anyone who reads this....

To sum things up, I have a 2004 Touareg V10 TDI with 64,000 miles. As far as I can tell its value is between 7-11k based on specs, mileage, condition, etc.

Both turbos need to be replaced - lets call that $8500
I'm also going to need tires for $1100
Brakes for about $1200

Given the resale value of the car, would it make sense to spend another 11k on a 2004 car (versus putting that cash towards something not 14 years old)?

The $8500 pretty much eats up the residual value all by itself. Are the turbos really shot or can they be rebuilt? [Just taking them off and putting them back will cost a thousand or so - maybe more]

The brakes and new tires are normal wear items and shouldn't count much towards or against the value. (ANY used car you get with that mileage is likely to need tires (soon) or brakes. Maybe not right away but within a few thousand miles.

I got multiple opinions and both recommend replacing both turbos. The dealer diagnosis was that the waste gates are seized on both and they're heavily corroded.

Yes 8500 pretty much eats it up. Hence my dilemma. :)

You are being BS'd! The turbos do NOT have any waste gates on them! In any case the waste gates, if crudded up, can be cleaned until they operate freely and reinstalled. Keep in mind the only function of a waste gate is to dump turbo boost, if excessive, to the exhaust. If the boost computer is working properly they are never used - the controls assure energy is never wasted compressing charge air unnecessarily.


The only time a turbo needs to be replaced is if a compressor or driver wheel fails (VERY rare). If the bearings are worn they can be replaced. Axial play on the shaft (s) is OK, radial play (under finger pressure) is not OK and indicates worn bearings.

Thank you for your feedback. I don't doubt there was corrosion or seizure, but maybe the VW Master Tech was not as familiar with the Touareg as I thought.

Don't let the title VW MasterTech fool you. It only means that someone in the shop had to be called that (and he probably has a bit of experience - more than 6 mo - but not necessarily any on the Touareg V10).

VW couldn’t fix my Touareg either. They also told me 4 times that they didn’t want to fix it. The Techs don’t know how to deal with such a car

That is very true. I had to go to 3 different dealers before I found one that was comfortable with the V10.

I'm not sure how handy you are at mechanical stuff, but the V10 to me is nothing more than an engine.

You can drop the entire engine and trans assembly with the vehicle on a lift by dropping the subframe assembly.

You can use oven cleaner to clean the stuck vanes on the turbos.
The vanes are what the "tech" was referring to as the wastegate.

Once you get them moving freely if you think you can do it, you can disassemble the turbine side of the turbo where the vanes are located and lube them up with nuclear grade anti-seize.

This link is just an example, there are other places to buy for probably less money.
