ESP and ABS is the big one that I can’t get rid of….. I really hoping it’s not a blown fried module…. I’ve replaced all Speed sensors, cleaned the multiple ring rings, haven’t done ABS rings, they actually look ok, but I might change them anyway just to be sure, the day after posting this we attempted a 3000k drive I blew the hubs out and sprayed heaps of contact cleaner in there and it’s stopped the constant ABS/ESP/BAS inoperative code popping up all the time. Made it 3/4 of the way…..
