Maybe but you really need to scan with Vagcom first to see whats going on as it's probably going into limp mode.

this is happening to me, fine for three weeks , came back yesterday, cleared when on motorway, but back again today. Any ideas please, anyone have this?

It sounds the same as the problem I had on my 1.9 Tdi. That was down to the turbo being clogged up due to it only being used on local runs. The Tdi turbo has variable vanes which will clog with carbon/soot deposits if underused.Try loading the car up with all your mates or a dozen bags of sand and giving it a good run up the motorway making sure you work the engine ie overtaking accelerating, going hard up through the gears to get the turbo hot, this will burn off the deposits and should cure your problem.

I've just taken all the bits off mine (see other post) and can not be certain it will solve the problem (car still in bits) but the inlet manifold was coated with about a 1cm of black gunge, the EGR valve was similar. Inside the turbo there was a lot of carbon build up, but my guess it that the sticking is cause by the vanes catching on the scratches where the vanes rub on the plate (hard to explain - I took a picture which I'll have to figure out how to upload). Anyhow I used some 400 grit emery paper and it is a smooth as a babies bottom. It is not an easy job to get it out, see http://sites.google.com/site/galaxytdi/turbo1
