so i took the car in and had a diagnostic run and it came up with... nothing. a few months passed, problem never reoccurred, but - the other morning the manual 'M' light flashed a few times (didn't count, sorry) whilst the car was in normal drive mode. didnt seem to impact the transmission at all but i guess its trying to tell me something.
a couple of other times whilst in manual mode and shifted into 5 the 'M' flashes and won't allow to change into 4, 3, 2 etc. Need to move gear nob into D then back to 'M' and its all normal again. This has happened maybe three times on different days during drives when Im in M but not using the paddle shift... the plot thickens
any ideas or similar experiences? any wisdom to share out there on this?
