[:@] driving down a dual carriageway yesterday and the light has come back on! really getting annoyed as to what it could be, as anyone got vag-com round the west midlands area that could have a look what could be causing it?

Had my car to a revo specialist and they've said thats its not the map thats not the problem, and they've changed my settings to HB 6 T6 and also changed my FPR from a 4 to a 3 as they said only need a 3 on stage 2 now.
They said that the problem is caused by a boost leak, which is making tha lambda sensor read incorrectly, causing it to over fuel.
Had a look for a boost leak, but can't find one, they did say it was under the battery but can't find it.

wtf, stage needs a 4 bar mate.

Boost leak will cause it to run rich yes, you need to log it ideally or pressurise the system and listen for leaks.

No, been to midland vw today and they say theres no air leek, but theres no boost to the car, they said after doing a 115 log the requested boost is 1.2 bar and the car is running 1.5 bar! could be the remap, or 4 bar fpr .. im really sick of it now, car failed a MOT yesterday because of this problem :censored:

Can you get any log up? My stg2 map spikes at just over 1.5bar holds for a couple of stamps then settles around 1.2bar then tails off to 1.0bar at the redline. Mine and phils are pretty much exactly the same so i assume yours would be in the same kind of range as your running HB8.

Logd would be a good start for us :)

no point in motorway in mine wont rev passed 3,500 rpm so 60 road is enough lol do 1 at a time really for best results. just dont like doing them as sounds horriable will get a proper video up to so can see and hear how bad it sounds.
