My local tyre fitter managed to catch and break the back wheel tyre sensor while removing a worn tyre recently. In fairness he offered to pay for it but as he charges me €5 to take off the tyres I couldent very well do so.
Anyway I picked up a second hand unit from Sherlocks which is now fitted. Its not working but I have something in the deepest recesses of my mind about it having to be initialised/matched using the BMW diagnostics.
Can anyone please confirm this is the case or have I bought a pup?
