The ABS warning light is illuminated all the time. My local BMW dealer wants to replace the whole thing at a cost of 1500 euros ..........we live near Avignon in France. I got a local guy to check out the situation and he says that the fault is in the front left wheel hub. The other 3 wheels ABS works but not the front left. If you interchange the wires, capteurs in french, the situation is the same ie front left doesn't work but front right does. From this he deduces that the problem is not the wire...capteur but within the hub itself.
If anybody could confirm this as being the answer to the above would be grateful.........or are there other scenarios.
Lastly the guy thought that even if his solution is correct and he changes the bit in the hub the light might well still be illuminated because the onboard computer has a memory and may need to be reset and he doesn't have a "valise"......computer, with which he could reset stuff.
I'd appreciate any help on this matter in plain english as technology is not my strong suit.
Thanks in anticipation
