I\'ll bet none of you \'know it all\' contenders knows the answer to this one...!
I want to change the clocks on my 2002 m620.
I've asked the peeps on UKMOC and some useful suggestions have come forward, but nothing definitive.
The new clocks are plugged in and the needles spin round, everything lights up, but the starter button don't work.
I have learned that the chip in the ignition key talks to a reciever in the clocks which sends an activation signal to the ecu if all is in order, but obviously the new clocks are expecting a different key to be used so tells the ecu to immobilise!
Question is this...
How can I make the new clocks recognise the old ignition key?
