Title: please help TURBO NOT WORKING! UPDATE***
Post by: jonnyturbo on 03 February 2011, 20:05

Well just been to shop and car was running sweet. Got bk in car and was just driving normal and thourt I would give it a blast nothing there at all. Boost gauge going from -20 and then sticking at 0. Can't here the turbo when I rev . Or Here the whoosh off the carbonio.  No chatter off wastegate either. Only two fault codes there is are 17963 charge pressure maximum limit exceeded ( intermittent ) and a lambda fault. Had them to before and car was ok. No blue smoke or nothing. Any ideas guys?

Could be the actuator jammed open? When my new one was put on slightly wrong i had the same thing......

Only to ya wallet! Lol. Nah its just like the ultimate boost leak. I wouldnt wanba leave it for linger than necessary though. May not be that. Could also be an intercooler hose off or something similar

sory about this but one of the pipes on my n75 valve is missing and it wont boost properly i think its over boosting , would that be the cause ?

yes it will try to overboost without that pipe

Jonny - suck each pipe, one of them should be near on impossible to suck through

Nice one, saved gettin all soggy on a sunday! Forge actuators are noticeably different if your old one has been getting gradually worse over time!  :smiley:

yup that'll do it mate. Overboost is probably it being stuck shut, then lack of boost it being stuck open.
