L200 ABS Pump ECU
 

Having a nightmare with my L200 Animal, truck failed MOT test due to ABS warning light not coming on. Local garage found that all of the warning lights had been removed from the printed circuit board of the Gauges.
New Dash Gauges fitted which now lights up like a Christmas tree with so many faults to the ABS system. They think I need to change the ABS Pump/ECU, if I get a used one will this need to be re-programed to the truck (as required on Mercedes) or is it plug and play?
