Part throttle surging
Posted: Sat Sep 03, 2016 3:40 pm
Another one of my cars small niggles that I needed to sort.
When for example I was joining motorways, I'd occasionally get a very slight surging between 2k & 5k rpm. You needed to be using all of the cars torque, but before the gearbox would kickdown a gear in order to experience the fault. Under full load it behaved fine.
So I hooked up VCDS and to my surprise I actually saw some fault codes logged:
2 Faults Found:
2636 - Low Pressure Fuel regulation
P310B 00 [096] - Fuel Pressure Outside Specification
2638 - Low Pressure Fuel regulation
P310B 00 [096] - Fuel Pressure Outside Specification
So with that stored, it was then booked into the dealer. They liaised with Audi Technical and I had a call on Friday saying that the decision was to fit a new fuel pump; this was ordered and should be fitted on Monday. Not sure which one, but imagine that it's the fuel tank one getting replaced. Hopefully that's fixed the fault and I can tick another thing off the list.
