156 Speedo & ABS issues
My 156 V6 Sportwagon had a symptom where the speedo would drop to zero when coasting downhill in neutral. Now some years later it has compounded to an eratic working speedo with the ABS lights coming on. Now its permanently faulty.
As suggested elsewhere on the Forum we have replaced the pump with another unit (2nd hand) but the problem persists, and the Independent dealers computer ( Snapon) cant seem to read the ABS ecu in order to find error codes.
Is there any other people experiencing this, perhaps a bad earth, wheel sensors?
I am sort of stumped for the moment, unless by chance the swap out ABS pump has exactly the same issues?
