@Niner
I am mostly well versed in the implications of owning a V10. However, your suggestions of 505.01 are what threw me off. You seem to contribute enough, but I think you could have worded your post a little............less douchey? There is no need to be condescending.
And yes, VW will/should cover my vehicle despite being 7/10 years old, because I have an extended service contract through Fidelity which I have stated several times over, had you cared to read and remember before posting.
@csTDi
Thank you for that bit of info on the oil and it reflects my understanding of the whole oil spec debate in the VAG automotive realm.
Lets not forget, this thread is not for oil discussion, its for the specific diagnostic code posted in the title and its resolution. I will keep it updated in that regard. I will post back any and all of my findings as I go along with VW service.
As far as North America goes, a V10 tdi motor may as well be a Ferrari, in terms of it's oil requirements. This it completely a
caveat emptor situation on a $70,000 wunderdiesel V10 motor with unique cam and injection design that VW and Bosch quickly terminated here in the USA... they ran with it for 3 years... 2004 through 2006... that's how long the PD design lasted in the USA...VW dumped it. As I said, caveat emptor.
I've stated what I know about V10's, pump dusses, and American motor oils. Slim pickens... do your homework before you jump in.
The PD is a simple system... if you are having uneven fueling problems, it 's a few things... PD injectors wrecked from running biodiesel in too high a percentage, over 5%, crank angle sensors fallen out or gone bad, or cam wear / follower wear, from running the wrong oil or abusing the motor at higher rpms and heavy loads too frequently, usually on the lobes of the valves, affecting breathing enough air and incomplete combustion, and lower rpms on that particular cylinder, which throws off the reading on the crank angle sensor, and it being out of spec.
Put it on VCDS and read what your fuel injection variances are on all 10 cylinders. Maybe think a little bit about what could cause your problems. Or search.
These are my observations... YMMV... but you bought a Ferrari, expect the finickyness and price tags for repairs that come with such an exotic SUV.
If you knew more VW history, from owning them longer, you'd know the history of pump dusse motors and their oil requirements. They all require a 5w-40 based motor oil. 505.01 meets that spec in all PD injector based motors.
The fly in the ointment is that VW put DPF filters on the touareg V-10 to meet DOT transportation pollution requirements with new ULSD.... VW put them on there as an after thought. It screwed you, the consumer,on suitable oils for both the PD design and the DPF requirements... they can NOT be met with any existing oil in the USA. 30 weight VW oil, all of them, wreck cams, 40 weight oils, most all of them, wreck DPF's. It's a catch 22 situation. One oil the ESP M, is not VW approved, but it is MB 229.51 spec approved, which happens to be a spec that all VW 507.00 oils happen to share with MB 229.51 approval also. So in a round about way, those are your options.... Wreck your cam with 507.00, wreck your DPF with 505.01, or try to save both with a 5w-40 MB 229.51 motor oil, and not worry about warranty coverage, it's over with on your 2006 anyways, isn't it? 5 years 60 k miles is it, correct?
BTW, being Dutch, I apologize in advance for my writing style,, not just this thread, all of them. Not my intent to come across as condescending, just seems to happen that way through the keyboard, knowing that Germans have high expectations of the knowledge of their car owners, and the service needs, something that kind of gets lost on most Americans.
Not saying you, that you did the tranny fluid tells me you are on top of your game, but the airfilters... maybe not so much???
My prediction is that your cams are worn, due to driving style, or injectors need R&R, due to too much biodiesel or water in your fuel... there are micro orfices the fuel passes through from the fuel rail to get into the injectors. too much biodiesel or water makes them rust up and clog up, and starve the injector for fuel to feed the motor under hard driving heavy fueling applications.
Drop your TDI off at the VW dealership and do not take it out of the shop until they fix the problem... you are too close to mileage to be out of warranty if your cams are worn out from 507.00 30 weight motor oil. Either way, they will need to pull the valve covers to inpsect the cam or replace damaged/worn/clogged injectors... so get a print out in the measureing blocks on VCDS for fuel flow per injector.... and the variances... I know it was in Group 13, Basic settings that I checked on VW ALH diesel motors. Find a TDI guru, log the readings, and get a printout in hand what the fuel flow variances are for all 10 cylinders, before you let the VW dealership touch it, and before you go out of warranty on the mileage on your V10....
