Sorry if this has been covered before, but only discovered this NG today.
The ABS light is on.
My local garage (not a Peugeot dealer) had the ABS interrogated to be told that it was a rear wheel sensor problem, They drove for 5 miles after replacing sensor and the alarm light returned. The computer diagnostics still insist that it is a sensor fault.
Are there known problems with the 307 ABS unit, such as faulty wiring looms which would give a chronic ABS alarm?
This is a most annoying syndrome because if one is a good driver, then a reason for the ABS to trigger might only happen once in 5 years, so a fault in a rarely-used luxury adornment makes the ABS a waste of time and money (Local garage has had the car for over a week now)
