Hello

Got a problem with a 1.9TDI car. It goes great until the revs get up
to about 3000 rpm. Then the power just falls away and the pickup is
really flat. This is a pain when towing.
The point at which this happens is a little variable, but 3000 rpm or
thereabouts sees the onset of this problem.

Anyone any pointers on what this could be. Its getting worse!.

Cheers... Rob.

Probably the MAF (Mass air flow meter). Expensive to replace but a common
problem.

Ack.

NACK. I don't think it's _that_ expensive and there's surely almost no
labour involved.

Update

A friend who owns an alternative VW/Audi repair business tested the
MAF, but initially found nothing wrong. He re-set the ECU memory and
told me to use the car and bring it back next day/if the fault
exhibitted itself. Gotta say the car was much improved after this, but
after a while, the fault came back. This was logged in the ECU as the
MAF.
Its gonna cost £125 (plus 17.5% tax) to replace, and the guy will fit
it free.

Thanks again for the help with this.

Cheers... Rob.

I had a similar problem with my A-6 4.2. At almost the same rpm and
under load it would hesitate (start missing) until I got the rpm's up.
It took seven times to the dealership for them to finally identify
the mass air flow sensor. It has been replaced and seems much metter.
