My exhaust emission light came on this morning after only having the car two days! (private sale, you take the risk)
I noticed before the light came on that the tickover at standstill had got erratic going up and down between 800 and 1200 revs?
Also before light came on I averaged 37mpg to work and on the way back it was only 32mpg both times at the same speed.
I plugged in a cheap code reader I have and it came up with no faults?
As far as I know the car Gti 2005 has not been recalled for the coil packs and ecu, do you think this might be the cause?
I have booked car in at my local independent garage on Monday for full diagnostics etc.
Just wondered if anyone had an idea what the problem might be?
Am i ok driving the car till monday, without ragging it?
