code 78
Hi,
I'm getting a code 78 (turbo wategate solenoid). It is intermittent at the moment. I was wondering what the implications of this were (besides the obvious possiblity that the solenoid is bad)...
should I jump on the solenoid or are more diagnostics in order?
Don't know if it's related, but I also have a belt chirp that seem to be coming from the area of the vacuum pump.
Thanks.
