Morning Guys and Gals,
I'm having a problem with my GTi, and I was wondering if anyone else had suffered from the same symptoms as everyone I speak to seems to come to a dead end.....
Symptom:Pulls hard in first and second gears until selection of 3rd gear and then no turbo, and will not rev above 3500 revs. Won't reset until ingition is cycled.
Diagnosis:Been to the VW dealer and the fault memory reads "Bank 1 system to rich"......on the guided fault finding it goes on about checking the "pressure side of the system is not hermetic" This is a check for the pipes being air tight......
They have checked, and even removed and refitted the intercooler pipes to check for splits and holes and they are all fine.
This is where I need help to go next, can't any further money at the dealer as they seem to have reached a dead end......could the Diverter Valve diaphram being split cause this issue?
HELP!
Thank you.
