Boost pressure regulation control
« on: June 02, 2021, 02:47:21 pm »
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.

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.
