HI all looking for advice / help with above i have just fitted rear leds genuine units . my car is 06/2001 i understood from various forums that i would require a replacement light switch and have it flashed/recoded.i obtained a secondhand unit from a 2003 M3 which had leds and zenon headlights i put this switch in all lights worked perfectly but i had the red dot come up next to the mileage display.i took my car to my local independant who recoded the system but now the dash display is showing rear lights out and the red dot.when the indy was programming it the computor displayed the original M3cars chassis number.
1 = I am hoping some of you can let me know if the problem can be sorted without buying a new switch from bmw.
2 = maybe tel number of independant in BUCKS that is capable of resolving this problem.
many thanks i look forward to your replies cheers TONY.
