A3 TDI 2 ltr - sudden loss of power - will only do 60 MPH

[buzzer]

Driving down the motorway earlier today i had a sudden loss of power with my A3 2lt TDI.... I stopped on the hard shoulder for a while and then set off, but the car would only do max 60 MPH...

there is no smoke from the exhaust, the car ticks over fine, what could it be?

Turn the ignition off and on again, is it then ok for a short while before it fails again?? If so sounds like its going into limp home mode.

Could be a number of things, but sounds like a turbo to me.

AA man has just fixed it! it was the pipe to the waste gate... it has come undone from a clip and was touching the drive shaft and had worn through. it drives better than it ever did now!

thanks again Tame...

by the way, the water loss has "almost" stopped since i put that K seal in.. I think it is a porous head...

Glad you got it sorted. I've yet to find a AA man that can fix anything, so you one up on me already.

Its not "technically" a waste gate, but I know the pipe, will have exavtly the same effect on the car (into limp home) as if the turbo's variable vains were seized with that pipe off.

I "could" point out that the pipe is supposed to be cliped to the trunking that runs at the back of the engine near the EGR cooler, and that "maybe" it was left uncliped which is how it ended up rubbing on the drive shaft. But that would just be mean,

Nice to hear its all sorted.

Harsh... but you are probably right Tame... How embarrassing... Hangs head in shame
