I just have my tyre changed from 18 inch M-tech rim with runflat tyres to 19 inch M5 rim with Michellin tyres. When i had done the installation, i tried to go to the vechicle setting in the i-drive, RPA, to reset the tyre pressure..... the status show initialising for about 10 mins didn't goes off.... i had no choice but to move my car. Until now, the status still show initialising..... Anyone can help???

 

It can sometimes take a long time, depending on distance covered. Mine used to take like a 10 minute drive, but since the last software update, it only takes about half a mile.

Tell your dealer if it stays that way and they should be able to sort it under warranty.
Has got nothing to do with the wheel tyre combo, as mine runs on 19", too

 

I don't think there's any warranty issue -- the car needs to drive for some miles before the status changes from initializing to active.

It will never change to active if you don't drive the car...

 

Had no problem with this issue.

Just make sure the car is standstill and it should
update it more or less at once.

Leave the RPM mode as soon as you have resetted it,
but remember to sign all modes (I hope you get my meaning).

 

You initialize while driving, like Rudy said. Start initialization and then drive off for about ten minutes. Procedure is in the manual.

 

I've always done mine driving, but before the latest software, as I said, it took a long drive and now after the software update it only takes a mile or so. So something certainly changed here.

 

According to the manual you should reset then drive off, it has to initialise while you are driving.

Initially mine reset almost instantly, but since I had my software updated - it can take 10-15 mins.
