Part throttle surging

Post by Surrey Sam » 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. :nodder:

Fingers crossed, the warranty list is mainly done now Mike. Will start an ownership thread soon I think.

Outstanding Audi stuff is:

Engine surging - New fuel pump hopefully fixes it
New Gearbox (questionable) - Meeting up with Riv to compare with his car. Need to ascertain if the new gearbox noise is a characteristic or mine has a fault from new. Audi believe the former.
Hill Hold Assist memory - Audi say feature only on 2014 cars after build week 22. Yet it's published as a feature in the user manual dated Nov 2013?

My own additional list:

Fit Akrapovic exhaust once all the warranty work has been done.
Body colour front and rear bumper matte aluminium parts.
PPF front end.
Get winter tyres for the 20" Rotors I have sitting around.
Remove OEM style window tints, perhaps get a light smoke all around instead.
Rob a bank to afford retro fitting Ceramic Brakes.
Learn how to wet sand, would love to remove the factory Audi orange peel.

Oh yes, for sure :thumbs:

How did the Triangle go? It seems like ages, since I last visited after the Scotburgring trip.
