Boost pressure regulation control

(1/1)

MKMike:
Hi,

Has anyone got experience with the below codes?



I've recently had a new turbo pipe and seal fitted by VW but the issue is still there. Will be calling them again when I get the chance. The indi that got me these codes said they need to get someone in to smoke test it.

pudding:
Clear the codes first and see what comes back because the first code could be related to the recent work.

If not, first code is usually a split diverter valve or worn out boost O rings.  Failing that, N75 valve not working or worn turbo/wastegate penny valve.

Second and third codes are related to the EVAP system.  Usually the N80 solenoid stuck open causing a lean condition. Sometimes a new carbon can is also required to shift the third code.
