Repair the ABS control unit rather than replacing it at great expense
If the ABS or ESP warning light stays on in your car, the TÜV will refuse the inspection — and the authorised workshop will quickly quote a four-figure sum for a completely new control unit. It does not have to be that way. Revonik GmbH repairs your defective ABS control unit directly at component level. Considerably cheaper than a new part, very fast and with a 24-month warranty. With the original unit, vehicle-specific data is retained in many cases. Coding, basic settings or further work on the vehicle may nevertheless be required, depending on the vehicle and the repair. For private and commercial customers.
Your benefits with
ABS control unit repair
If the ABS or ESP warning light comes on, an expensive new part does not automatically have to be fitted. Revonik tests the electronics, the pump motor and — where provided for the assembly — the hydraulic function, and repairs the original unit where this makes technical sense.
Testing the original unit
Where possible, we test your existing ABS/ESP control unit. If the original unit is repaired, vehicle-specific data can be retained in many cases.
Technical inspection
Depending on the assembly, we test the power supply, the internal electronics, the pump control, the pressure sensors and relevant communication faults.
Cost-effective alternative
A professional repair can be up to 70 % cheaper than a comparable new part. Before the repair you receive a clear basis for your decision.
Clear processing time
We generally process standard repairs within 2–4 working days from receipt of the unit. For suitable standard faults we can review a 48-hour express service on request.
24-month warranty
A 24-month warranty applies to the repair service carried out. The scope of services is documented on the order and the invoice.
Transparent diagnostics
Testing starts from €69.00 incl. VAT. Before any repair we inform you about the findings, the price and possible next steps.
Alternative if the unit cannot be repaired
If a repair does not make technical or economic sense, we look into a suitable replacement solution and the scope of data transfer or coding required.
Full transparency –
no hidden costs:
What does the
initial diagnosis include?
We put your ABS control unit through its paces on state-of-the-art test benches. The diagnostic fee will be charged in full in the event of a subsequent repair.
What is the E-Part repair?
Includes the professional repair of electronic defects on the circuit board of your ABS unit.
What is the pump motor repair?
This includes all mechanical and electronic work required to repair the ABS pump motor.
What is the hydraulic repair?
Includes all repairs relating to the hydraulic part (valves, block) of the ABS unit.
Is your ABS indicator light permanently illuminated?
Do not ignore these warning signals. Failure of the anti-lock braking system (ABS) jeopardises the safety of you and your passengers. In addition, your car will immediately lose its MOT licence. Typical faults that we rectify on a daily basis include.
- No communication with the control unit possible
- No brake pressure on any of the wheels
- ABS pump runs constantly (even when ignition is switched off)
- The vehicle pulls to the left or right during emergency braking
- A valve in the hydraulic block does not open or close
- Pump motor / return pump fault
- Wheel speed sensor error (despite intact sensors)
- The ABS/ESP warning light is on continuously
- Various CAN bus errors
- One or more wheels lock while driving
- 5DF0 / 5DF1 / 5DF5 Pump motor
- 01276 / 04FC ABS hydraulic pump
- 01130 / 16352 / 3FE0 Control unit defective
- 5001 / 20481 / C1001 Internal fault in component N30/4
What happens if you ignore your ABS warning light?
Increased risk of accidents
A defective ABS control unit impairs braking performance, especially on wet or slippery roads. The risk of an accident increases considerably if the vehicle swerves during emergency braking.
High repair costs in the authorised workshop
What can be repaired at component level today often leads to an expensive complete failure tomorrow. The longer you wait, the greater the damage - and therefore the costs.
Loss of TÜV approval
With a defective ABS control unit, your car will not pass the next general inspection (TÜV). This will result in further costs and an absolute driving ban.
Loss of vehicle value
An unrepaired ABS fault massively reduces the resale value of your car. A well-maintained, fault-free condition is crucial to maintain the value.
The consequences if
you do not have your unit repaired:
Do not ignore the defect. ABS failure leads to reduced braking performance on wet roads, immediate loss of MOT approval and a considerable loss in value of your vehicle. What can be repaired cheaply at component level today will become an expensive complete failure tomorrow. The longer you wait, the higher the subsequent costs will be. Avoid unnecessary risks - start your repair order now.
This is how we repair your control unit
Diagnosis & Removal
First have the fault memory read out in a workshop and then arrange for the ABS unit to be removed professionally
Order & Shipping
Fill in our online form, pack the device securely and send it to our diagnostic centre in Kerpen.
Inspection & Repair
We carry out a comprehensive inspection of the device on our test benches and, once you have given your approval, carry out a reliable repair (typically taking 2–4 working days).
Payment & Returns
After payment, we will send the repaired device back to you immediately and securely packaged (shipping: €14.90).
Installation
After professional installation your vehicle is fully functional again. With the original unit, vehicle-specific data is retained in many cases. Coding, basic settings or further work on the vehicle may nevertheless be required, depending on the vehicle and the repair.

Frequently asked questions
On this page you will find answers to frequently asked questions
about control unit repair.
How long does the repair of an ABS control unit take?
After the unit arrives, typical repairs generally take 2–4 working days. With complex faults, follow-up questions or missing components, processing can take longer. You can request a 48-hour express service for suitable standard faults before shipping.
Do I need to send only the control unit or the complete hydraulic block?
That depends on the fault pattern and the design. For purely electronic faults the control unit alone is often sufficient. For pump motor, pressure sensor or hydraulic faults a different form of shipment may be required. Please send the part number, the fault code and a photo of the unit label in advance.
Does the ABS control unit have to be coded after the repair?
If the original unit is repaired successfully, the data is often retained. Whether coding, a basic setting or bleeding is nevertheless required depends on the vehicle and on the work carried out.
What happens if a repair is not possible?
After the inspection you receive feedback on the findings and on possible alternatives. Any further work is only carried out after your approval.
