2001 AMK S3 17963 - Boost Pressure Control: Upper Limit Exceeded
Brand new to the Audi-Sport forum, first off thanks for saving me a little bit of money on my car insurance :sex:
Purchased a 2001 Audi S3 AMK at the weekend.. very happy with it apart from one issue it's developed.
When I put my foot down in 3rd the boost comes on as normal, then when it hits about 4k rev's the turbo shuts off and sort of goes into 'limp' mode.
I borrowed a mates VAGCOM from work and did a fault scan, only fault it found was 17963 - Boost Pressure Control: Upper Limit Exceeded.
I cleared the fault and went out in the car again, put my foot down in 3rd and the issue happened again - back to the VAGCOM and the fault was back again.
Cleared the fault again tonight and logged block 115 after reasearching on here and other forums - log proved that the car achieved 2490mbar boost when requesting <2000 then went into limp mode.
I've uploaded the log here if anyone would like to take a look https://docs.google.com/file/d/0B9EE...it?usp=sharing
After researching already everyone seems to suggest the N75 or N249 valves, anyone with experience of this issue say this cured their issue? If so I'll check all piping on Saturday then go out and buy a new N75 - is there a specific part no. you'd recommend?
Other than this VERY impressed with the S3 so far, after coming from a MK2 Golf GTI (and shamefully a Peugoet 206) this is a brilliant car.. :p
Going to try and give the car a full detail at the weekend also, will post up some pics afterwards :moa:
Thanks in advance!
