I have a 2006 touareg V10 with 174,000 miles that had the turbos replaced at 65,000 miles and since this last winter it will occasionally drive ok until I put my foot in it and then it has little or no acceleration. Now its happening maybe one out 6 starts. When it happens I pull over and stop the rig and take the key out, wait a few seconds and restart it and then its fine. Only once did a get a check engine lite on the dashboard? That happened 2 months ago and never since. Has anyone had these issues before ? Its weird,so when its in limp mode the rpms can get up past 3000 but its
still like a slug at that point? I thank you in advance for any impute.

Do you have VCDS? Do an autoscan and post it.

Sounds like if the RPM gets going but no 'push' would be a clue that there is something wrong with the boost. Sometimes this will throw a code and sometimes not. Look for reasons there is no boost and ideally get a VCDS readout of boost pressure while this is happening.
V10 turbo actuators are known to 'stick' and move slowly - might have something to do with that.

So here is the codes from the dealership regarding my v-10.... any help is greatly appreciated.

also could this be an issue despite the error codes ??

If your vehicle goes from running ok to not (no power) it is likely a "C" clip that holds the linkage on one of the turbos from the VNT control servo...when the c-clip comes off the veins in the turbo will not operate and thus no boost...if your dealer can check that it would be a good thing to rule out. Problem is the dealer may not want to as they won't make much money if this is the case.

If the “e-clip” is gone the code would not be intermittent but steady. Please remove the wheel well liner, feel the actuator lever and make sure it moves freely. Folks often ignore or are unaware of the V10 maintenance item to grease the clips every 10,000 miles with hot bolt paste. I’ve also thought about checking and lubing the upper ends of the levers.. Access is almost impossible though.

Reminds me to do this asap!
Will try and reach it from underneath

 

[joefeuerstein]

I assume that would be both wheel well liners ? and the levers in question come off or directly to the turbos?

 

[joefeuerstein]

so here is a pic of the passengers side turbo with what I believe is the lever in the middle of the pic … it moves a little but not much? am I correct in thinking this is where I need to put the "hot bolt paste" this lever goes up into the abyss but at least I can lube this connection, any impute is greatly appreciated.

 

[lgibson]

Yes, that’s the lower end which often loses the eclip, mostly due to corrosion which is never an issue down here in the southwest. I am able to reach the passenger side at least from above with a dab of grease on the end of a welding rod. IIRC the driver’s side wheel well liner has to come out for access. Looks like you have a lift.

The fact that it moves a little, but not much is concerning. It is possible for the linkage joints, up to and including the VNT vanes inside the turbo are sufficiently fouled to require disassembly and cleaning. With the 'C' clip and the actuator lever disconnected it should be possible to move the mechanism full cycle freely. It it is too difficult, the actuator doesn't have enough torque and throws a code. If grease doesn't free things up disassembly may be necessary.

 

[joefeuerstein]

just got done putting the wheel well liners back on... what a pain in the … so I quess I should of taken the "e clip" off to try and move the long rod that goes to the turbo? Man, I need smaller arms to do this...

I guess I would like to know if my intermittent problem is how these turbos go before complete failure ?? cause its been about 6 months now?

disassembly means pulling the engine I assume

 

[joefeuerstein]

So I am wondering for all of the v-10's that have had to have their turbos replaced, do the turbos just blow up one day and not work at all.... or do they have intermittent dysfunctions like mine does until they stop working at all? again thanks to all for your help!!

They don't blow up.

They do get sticky.

Matt Phelan is the guys name, he's a V-10 TDI guru.

You might want to pay him a visit, he can very probably get your turbo's cleaned up and working correctly without having to drop the motor.

You bought a beast, they are a PIA and expensive to maintain. No two ways around it, when you shoehorn that much motor and transmission into a tiny Touareg engine bay. Major, major heat dissipation problems with that engine and engine bay size and configuration, constantly.
