V6 TDI sudden loss of power

**Ricardo1** · 21-08-2012, 03:52 PM

This has happened 6 times within the last 3000ks and VW service cannot fix as no fault codes/indicators to help diagnose. Treg looses power and engine shudders, but does not stop, when accelerator is pressed. Blip the throttle a few times and problem goes away until next time. Changed air and fuel filter and am now conviced it's the turbo but with no fault codes VW service will not move on this. Occurred twice on our trip up Cape York and now back in Cairns and thinking of cutting the trip short and heading home. Anyone else had similar problems? Scary but luckily not occurred with a B-Double behind yet!
Cheers, Ricardo1

What year Touareg we talking about?

Perhaps it's worth investing in a cheap in-car video recorder for the next time this intermittent problem occurs. Ask the service team if video footage would help them and be enough info for them to take action. There are various cameras on eBay.

2007 V6 face lift TDI. Been good with just the regular problems, replaced centre carrier bearing on drive shaft at 110,000ks and flapper motor issues a couple of months back, all done on extended warranty. Good suggestion to video the problem, will keep the iPhone handy for the next time. Cheers guys.
