Your wheel sensor signal IS the problem. 100% certain.
Without a wheel sensor pulse, the Mk2 will not work.
Conclusion: Mk2 is 99% likely to be OK.
Find the missing wheel sensor pulse and fix it.
Does your Speedo still work?
Do you have an ABS-warning light on?
If you have speedo and/or ABS warning light problems, the fault is likely to be the actual wheel sensor.
If ABS and speedo are fine, then the fault is in the wire from ABS control unit to nav. Check nav connectors first (easy to access), then check ABS connector.
Post your chassis number and I'll advise what wire colours to focus on. |
When I got the car, the speedo was not working. The ABS light was not on, however.
I took it to my BMW guy and he fixed the speedo problem. It was a module and not a sensor. He said that at least one of the wheel sensors (I gathered that there are several?) looked to have been newly replaced.
Although the ABS light was not on and is not on, an error is still coming up in the computer diagnostics indicating that there is some sort of sensor issue. My mechanic thinks that someone messed with the dash ABS light...
My BMW mechanic is actually the best in my city, works on BMWs that are raced, and known nationally. But, he admits that nav systems are not his thing.
Should I just have him go through the trouble of individually testing all of the wheel sensors? It sounds costly and time consuming...
