MAP & MAF Sensors

Hi Guys

Got a TDI 110 ASV thats having occasional limp modes. I've had the turbo cleaned and replaced the vacuum lines and also the N75.

So that kind of leaves the MAF or MAP sensors. Which one would most likely cause limp mode and what are the best aftermarket brands as I don't feel like spending the cars value on dealer parts.

Cheers

Unplugging the maf definitely causes power loss, I suspect it could be the MAP sensor so i'll give it a clean this weekend and report back.

It's doing it both up and down hill now which I find strange. Normally overboosts cause limp mode but it must also be recording an underboost too.....
