This Volkswagen Transporter came into the workshop with a number of ABS faults including a control module fault. The customer advised us the ABS ECU had previously been sent off for repair. As the ECU had already been tested and the ECU testing company had not found any faults were extra picky when looking for faults.
Once we had opened the ECU we could see very little in the way of damage to the PCB. We found some poor solder that we had to rectify after 1 hr of carefully searching for faults we could find no damage apart from some dry / poor soldering.
We advised the customer we could source a used ABS ECU and pump as this is combined on the VW Transporter. The new / second hand ECU and pump would only need coding and this would fix the issue.
