Wabco EBS3/EBS4 Steuergerät EvoBus Citaro

Anyone who repairs ABS control units on a daily basis will be familiar with the scenario: the ABS warning light is on, the diagnostic scanner shows no communication – and the garage recommends a new control unit costing several hundred euros. In most cases, this isn’t necessary. Revonik will repair your Wabco EBS3/EBS4 Steuergerät Professional service, delivered in 2–4 working days, and up to 70% cheaper than buying new.

Common fault patterns

  • The ABS/ESP warning light is lit continuously on the instrument panel
  • Unable to communicate with the diagnostic tester
  • Wheel speed sensor fault despite sensors being intact
  • The pump motor runs continuously or is no longer being activated
  • Faulty control of the solenoid valves in the hydraulic block
