Hi - Loss of power through all the gears. Will accelerate but I have to be VERY gentle on the pedal, too much and it just gradually gets slower. Dropping down gears does not help. Even if I take it out of gear and press pedal still not as much revs/power as usual. Thanks

Worth checking the air mass flow meter.

Blocked catalytic converter. Jack it up and look underneath while someone revs it hard for a minute. Cat glows red hot = Cat blocked.

Sorry. Just re read your post. Not sure whether the diesel has a Cat. Apologies if bad advice.

Had same issue on a 110bhp passat, new maf solved the problem. Bought a Merc spec one from someone in the US of A for somewhat less than dealer prices. The Merc ones are a bit more robust. You could try cleaning it with an alcohol spray.

unplug the MAF wiring and take the car for a run down the road it should drive ok, then pull over and plug the MAF wiring back in if the car is slow again is the MAF that faulty hope this helps

Someone is selling MAF's on Ebay for a good price (Bosch, I believe) and seems to have a good stock for most models. Have a look...

I'd confirm the advice of cdl123. I had the same issue on my Passat 1.8t (petrol turbo). It ran like a dream when I disconnected the MAF (except that it wouldn't idle). My MAF is located on top of the air filter housing. If you're not sure where yours is, I'd suggest a look at the forums in tech.bentleypublishers.com or forums.vwvortex.com
