E46 320d FL MAF issue

[Boytjie]

Hi

I am having issues with the maf, on Inpa I am getting Maf error and car has no power. So bought one from a spare shop, now no errors but still no power. Inpa maf reading shows only 38, so replaced the maf with a working one from another car and still getting low maf value on inpa.

When I unplug the maf the car pulls alot beter.

any ideas?

Hi,

I'm no expert, but from what you describe, it sounds like the turbo isn't working correctly. Does it spool up? Perhaps there is a problem with the fuel pump or injectors?

Thanks, correct. The found that the pipe from the MAF to the turbo is broken. No Maf reading went from 30 to 320, think it is still bit low.

On low revs the car is still bit dead, but fulls normally from 3500rpm.
