Rob, I thought about reusing my original ones but instead I bought these new genuine BMW ones for my new wheels and they worked straight away without me having to do anything other than initialise TMPS on iDrive
Price was good and the guy was great to deal with and I had a query on a Sunday and he was back to me within 10 minutes
