I could use some advise. I've had the car for two weeks now and it has 126K miles. This is the only TDI that I have ever driven so I can't compair. The car runs great (I think), it will get up through the RPM range quikly ( 2500-3000) during normal shifting but RPM will slow after 3500. After reading this site, I removed/cleaned the EGR and intake, which it needed with only about 1" of passage. After the cleaning there was a big difference in getting up to the RPM but it still slows from 3500 to 4700. Is this normal or do I need to replace the MAF ?
