P129F 😬
« on: January 31, 2018, 11:22:52 am »
Has any1 had a P129F VAG-COM fault code:

004767 - Low-Pressure Fuel Pressure Regulation: Pressure too High

I deleted it and two weeks later it was in the fault memory again.

I’m booked in for a stage2 at r-tech with Niki Gower in a couple of weeks and want it to be 100% before.
