Audi A3 TDi X Reg. Power dropping - VAG.com in WF8 area ?

[JezzaL]

Hello,

The power when accelerating on the motor way is dropping so when the accelerator is fully depressed there is nothing there. You can get acceleration if you depress the pedal slightly. Very frustrating.

I have replaced the MAF recently.

Does anyone have VAG.com in Pontefract area, or any ideas ? It has been suggested a bit back that there may be a split pipe letting to much air in, so the car goes into idle mode ? I guess it will be tough finding where.

any help appreciated.

thanks.

I have exactly the same problem as you, I recently changed the MAF and N75 Valve and today the fuel filter. The car was put into the audi garage for a recall to replace brake vacuum hoses and the problem seemed to have surfaced since then. Im on the hunt for a split hose now myself I can hear a hissing from the vacuum capsile on the inlet manifold. Also when i had it check with VAG it showed up an error saying the inlet manifold pressure was to high.

Yeah i changed the MAF aswell, based on others comments on this forum, no joy.

Let me know if you find anything, and any photos of offending part much appreciated !

cheers.
