Dear all

Im new to this forum, i have had my Audi A4 2000 B5 saloon 1.9Tdi 110 for 9 months, she went through jer MOT yesterday with minor bits and bobs. Shes always been a bit sluggish more so recently and getting worse.

I tried a new MAF which gave very bad hesitation on accceleration right through the rev range until i got the fault code 17964 which means im now in limp mode.

I have checked the vac hoses and they all seem fine (ordered replacments just in case) also the VNT actuator seems to be working as i excersised it in VCDS and the N75 valve appears to be doing what its supposed to.

Cleaned gunk out of inlet manifold

Running low on ideas!

Any help much appreciated!

Cheers

Adam
