Hi there thanks for the replys
I didn't reset the ECU and glad as I don't have the radio code.
It's a Audi a3 Quattro 1.8t sport apy 2003
Right i'll start again with whats happened/happening now.
I have only had the car 4 weeks.
Last week I took my mate out for a blast, all was fine but when I turned the car on the next day the engine management light was on so I got another mate to scan it and it brought up these fault codes.
16486... 16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low
16795... 16795/P0411/001041 - Secondary Air Injection System: Incorrect Flow Detected
17705... 17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
So after getting these codes he reset them. Since then the EML has not come back on.
I tried disconecting the MAF the other day but only took it on a short run as the traction control light come on for some reason while the MAF was disconected so did'nt really feel much of a difference, connected the MAF back up and the Traction light went off.
So anyway today I gave the MAF sensor a clean with Isopropyl spray to see if it would cure the 16486 code.
Called my mate up to check to see if any codes where there again and there was these...
16486... 16486/P0102/000258 - Mass Air Flow (MAF) (G70): Signal too Low
17705... 17705/P1297/004759 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
But these 2 codes would have been loged in the ECU from when I diconnected the MAF at a guess.
Then we reset these again, took it for another drive and now I have no fault codes.
The car seems a lot smoother and quicker so hopefullly that has cured it.
We found that the oil dipstick tube was broken and dip stick was just sitting on top of the tube... maybe this was causing the stalling as air would have been getting in??? For now I have just put a load of insulation tape around the dipstick so it fits in the tube and not drawing any air in.
JoJo you say could be a knackered temp sensor or cam sensor, would these show up as fault codes if they was faulty because it didn't?
What do you think dudes?
