2001 Speedometer Problem
 

Neither of my speedo's work. I posted some time ago, but thought I would repost this in case someone has recently come across this problem. Chatted with a guy yesterday that says I need a new M535 & transponder.

I thought it would be the brake controller or CAN BUS....



The Odometer doesn't work. The spoiler doesn't retract. The ABS light on the days stays lit.

Any ideas?
