hi guys. just wondering if i could get a bit of advice on this one...
ive recently bought a mk5 GT Tdi 140ps. it has an engine management light on and its pretty poor on fuel and has a real lumpy idle.
plugged into it with a solus and got, mass air flow - implausible signal and egr not flowing. if i reset it it will stay off and the idle seems better until the light and 'emissions control' flashes up after 30 miles or so.
the mpg seems to show 20-30mpg around town. if i put fuel in itll come up 100 miles and itll seem to reduce 5 miles on the computer for every 2 miles you do
the only other thing is it does have a slightly leaky boost pipe coming off the driver side of the intercooler (just hisses a bit)
so my question is, is this the egr, maf, boost pipe or something else? i know the maf monitors the egr so im not sure which way to go with it?
thanks all
sam
