    No new Borgwarner TDI90 turbo's in the Country???

    I have posted here before about my bad experience trying to get a TDI90 turbo refurbed. To recap, in short, it seemed the refurb company couldn't accurately set the stop screw. This resulted in no boost below 2100 revs and then a great surge above 2100 revs. I gave them three attempts and ruled...

    My A2 is a hairdryer. Help!

    My A2 1.4TDI drove like a hairdryer this morning! No power at all. In the end it did manage to get to 60mph, but it really wasn't right. I stopped after about 15 miles, dropped my daughter off at school. When I got back in the car - it was fine - accelerating as it should. Has anyone else had...
