Loosing power, but come on after "restart"

Superb_Norway · 30-01-2008, 23:03

Hello...

My Superb 1.9 TDI AVF engine has a problem. When I accelerate "hard" soon after I start driving, the turbo stops working, and I loose power.

This happens almost everytime, espesially when I starts driving uphills. But when I turn the engine off, and on, the turbo is back and then I work all time, no problems.

I've been looking for loosen wires, but I can't find any. It seems like the problem is elecrically, because it's ok after a turn engine off and on.

Any tips?

Sounds like a classic case of limp mode caused by overboost.

This is generally caused by the VNT vanes on the turbo not moving correctly.
