Hi again,
I tried disconnecting the MAF, it idled very roughly at around 700 to 800 rpm, plug the MAF back in and it idles lovely at around 900rpm. I checked the two large plugs that go into the ECU, spotless. It seems from what I can find out there's no idle control valve on the fly by wire throttle bodies, the butterfly is controlled by the ECU. It's the same TB as the 500 I think. I'll check the earths
What gets me is it started doing this when it was just over a year old, then it didn't happen again until just about 2 1/2 years old. I had it booked in last year for a check before the warranty ran out, but the garage closed because of covid, and now it's out of warranty.
I don't like taking my cars to main dealers.
