Title: I'm baffled some help please
Post by: 1stevester1 on 30 October 2012, 19:04
this problem has stumped I brought car not so long ago and it seemed to have boost problem I could feel it kick then stop then kick in again so got a code reader and yup it came up with 17705 boost leak great so I reset the code as it was they only one that came up took the car for a quick td and it was jerking and I couldn't accelerate so came back disconnected the maf it drives like it did before so I baffled maf was fine before but now not cannot see that resetting a code has caused the maf to be knackered it's and auq if anyone could come to the rescue most appreciated

Yup running fine but you could feel the turbo kick in then slightly hold ack and then kick back fitting a boost gauge the weekend to try sort that one out. But the maf yeah definetly got me thinking so going to replace it with an genuine unit tomorrow then check for codes again

Mine had that sort of problem, think it was the n75 valve at fault, spikes early then boosts when needed, so basically it overboosts befor it's ment to  :huh: haven't explained well but hopefully u get the gist of it!!!

I had this, it was diagnosed as a faulty DV so I replaced with a 008. It cleared it partially but then returned and held back instead of boosting. Replaced the MAF and its ok ATM.
