A4 Multitronic-strange behaviour

[Toto89]

Hi guys,
I drive a B7 A4 2.0 PD TDI Multitronic since february this year. Today when i departed home the car behaved quit strange. First everything went good as usual but about 2 minutes later during accelerating I noticed that the car doesn't really wants to move like it did before. If engine is cold, the CVT box lets the engine to rev up a bit higher (~2500rpm) and the car moves a bit slower. But today it was MUCH slower, even at full throttle. The engine was revving at 3000rpm and the car was still slow. A few minutes later things started to work properly, it accelerated as it should. But it came up again and again on my way home. It was only about a 15 minutes journey so the engine couldn't heat up properly but it never did this before! For me it was looking like the gearbox didn't want to work for a moment. Although i tried once in manual mode and it did the same. I do not think it was the engine because it's always slower on cold run but not that much.
What do you think?

Worn clutch disk?

At 25000km on it? Don't really think. And I only felt it once (yesterday), no before and-till now-no after.

Get it on VAGCOM and check for any fault codes...
Or it may be the gearbox/clutch on it's way out a friend of mine also had a 2.0TDI Multi and he first had alot of power loss then 2-3 days later the gearbox and clutch both completly died on him! (His car only had about 8,000 miles on it so u never know)
Good luck hope u resolve the problem. :thumb:

Problem solved, it was the exhaust gas revolving valve (don't know how to say in English:confused: )When it started to work incorrectly, car's computer recognized it and limited the engine performance. I was glad that it wasn't the gearbox that caused the problem. It had been changed in warranty.
