Hi all

I drive a 2014 A3 2.0 184 (with DTUK)

I had the flashing coil the other day after pulling out of a junction. Car drove fine no limp mode. When I went out later the coil light had gone out and still driving fine. Done >100 miles and no problems.

Did a scan today and found a few fault codes in the engine module and one in the CAN module for steering that all popped up last week.

Any "best approach" here or just start cleaning sensors and checking wires?

Thanks, Kristian

DTUK? As in a tuning box?

Remove that before you start engine diagnostics - it's made to make sensors read wrong*

(*well, actually alter the signal sent from them, so the ECU sees different values to what is really happening)

Thanks, it took me far too long to consider that as a culprit given that I changed the settings about a week ago. I’ve set them back, will monitor.

I removed the box a few days and cleared the codes. Car has fault code again but just the boost sensor.

edit: i'll check the wiring and i think i saw a vacuum pipe going to it as well. can i assume there is no red herring here and i need to replace the boost sensor.

acceleration is less nimble and the throttle feels heavier, car feels a bit slower, but it does drive with no limp mode. if i clear the code car is back to normal until i can feel the heavy throttle again after a number of miles.

thanks for that, that sort of thing was over my head. I replaced the sensor took it out and fault cleared on its own. Fingers crossed all sorted
