[QUOTE="mcatrophy, post: 1441976, member: 3187"] I've never heard of this one before, but some thoughts: I don't think it's likely to be a sensor issue, or the ABS system would be complaining. The sensor signal feeds directly into the ABS control unit. As far as I can tell, the ABS control unit tells the ECU what the speed is (whether it's a sensor frequency signal passed on or a coded speed message I don't know), this then tells the display unit the speed - I’m pretty sure with a coded message. To me, the most likely cause would be within the display unit itself, but there's no certainty. First action, as RossKean suggests, check all connectors associated with the ABS control unit, the ECU and the display unit. [/QUOTE]
