Help needed .
I had a rear tyre slow puncture in my non run flat ,the idrive told me which wheel ,(it was a nail in the tread ) it was so I took it to the nearest tyre shop and they repaired it for me . they didn't reset for me as it was late in the day
But since this repair I am unable to reset the tyre pressures as the intalisation button is 'greyed' out so will not let me reset it .from idrive .
The idrive puts up a message ' ftm system error ' in idrive and the obc window in the cluster puts on a yellow warning message .
I know the wheel speed sensors give the system readings from tyre size rotation,I have checked them and they are all working from a hand held diagnosis machine
So I can assume it's not a duff sensor
Is it a case of just putting the correct tyre pressures , in as have read on the net that it is critical to put the correct pressure or have I got a software coding issue
Before the puncture I had no idrive messages with this
I have set pressures to psi 32 front 38 rear with no issues before puncture
Help!
