A common failing part on all Mercedes Sprinter vans from 2000 – 2006 is the Bosch 5.7 ABS Pump & module unit. There are many faults this unit can have but one very common fault is the C1401 fault code.

Fault Code: C1401 – Return Pump Fault

The above fault code is a very common problem with this type of ABS pump and will cause the ABS light to come on. It is an internal fault within the ABS pump and modulator unit and would normally require replacement at a very high cost.

The fault is due to components running at 70% maximum threshold for long periods and eventually become faulty. Replacing it with a like-for-like part will solve your problem short-term but expect the new part to develop the same fault in the future.
