Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, for a C1401 I'd have suspect either a bad abs pump or a bad abs pump relay. Have you tested the pump to see if it even works?
If you have not replaced the relay or tested the pump I would start there. I assume that you have closely inspected the connector to the abs hydraulic unit for corrosion. It's a common problem for water to leak out of the windshield washer bottle and corrode the connector or damage the unit. I'd also inspect the ground connection for the abs pump behind the left headlamp.
Let me know if you have any questions.
