Removal tips

Depending on the vehicle type and equipment, the devices are installed in different places. If you do not know exactly where your device is in the vehicle, please contact a qualified person or our service hotline on 09001-223 223 (0.49€/min. from a German landline).

Unfortunately we cannot give any instructions for all vehicles and types at this point. Depending on the vehicle type, ABS/ESP devices can be removed from the vehicle with or without a valve block. For some devices we need the valve block together with the control unit for the repair. For the affected devices, you will be explicitly requested in the repair order to send us the complete device. For all other devices it is usually sufficient to simply remove the control unit and send it to us. In the following you will find some instructions for the removal of various vehicle types.

Removal of the Audi/VW A4, A6 and Passat units

Removal for BMW E39

(year of construction approx. 1997-2004)

Here the removal is very simple. All six TORX 20 screws are easily accessible. The plug can be disconnected after loosening the lock.

Please notie: in a series E39 (year of construction approx. 1998) the active control unit is located under the glove compartment in the vehicle.

Removal of ATE units BMW Z3/E36

The photo shows the ATE device in a BMW Z4. You can loosen the device by removing four Torx 20 (outside Torx) screws. Sometimes the brake lines are in the way to disconnect the unit from the valve block (BMW E36).

Removal ATE MK 60/70 unit on a Ford Focus/C Max

When removing the battery, first remove the entire battery box. After disconnecting the cube plug, the brake lines can be removed from the device. This is somewhat difficult due to the very narrow installation space. Now a Torx screw has to be removed from the retaining bracket, and the device can be pulled out completely with a little skill past the brake lines. The brake lines should not be bent and the threads should not be damaged, otherwise problems will occur during reassembly.

When installing, make sure that the cube plug is locked in place. The brake lines should be checked for leaks after assembly. Ventilate brake system and valve block according to manufacturer’s instructions (with OBD diagnostic tool). Maximum pressure of the venting device is 1.0 bar.

Device installation instructions

Installation instructions for devices without valve block

Please pay attention to cleanliness during installation. The sealing flange and the seal of the control unit should be cleaned with a clean cloth and some cleaning agent before installation and checked for damage. Please switch off the ignition on the vehicle. Place the control unit on the valve block and tighten it again with the screws. Always tighten the screws crosswise (please note torque). Optically check the plugs and contacts for oxidation and damage. Now plug in the cube plug and the plug for the hydraulic pump (not available with all control units). Switch on the ignition, all signal lamps should extinguish after approx. 3 seconds. The error memory should then be read out and deleted. The function of the ABS should now be checked and verified on a brake test or during a test drive.

Installation instructions for devices with valve block

Please pay attention to cleanliness during installation. Please switch off the ignition on the vehicle. Reinstall the control unit according to the vehicle manufacturer’s instructions. Fasten the brake lines to the valve block again with the prescribed torque according to the manufacturer’s instructions. Plug the cube plug back into the device. Now you can delete the fault memory after switching on the ignition and verify/check the electronic function. The brake system must now be vented. Carry out this work according to the manufacturer’s instructions. Since the valve block has run empty during removal and transport, a venting procedure prescribed by the manufacturers via the diagnostic software must be carried out to completely vent the valve block. At the end of this process, the hydraulic valves and the hydraulic pump are actuated during the normal venting process to remove air bubbles that have accumulated in the valve block. After the venting process, the fault memory should be deleted again and the function of the ABS/ESP should now be checked and verified on a brake test or during a test drive.

If your control unit does not work

If your control unit does not work, there may be several reasons for this. We have tested and repaired your control unit. Should we have noticed during our incoming inspection that your control unit was working, we would have informed you immediately and only charged a handling flat rate. Therefore, there is probably another fault in your vehicle.

Please check the following in case of a malfunction:

  • Are all plug connections re-established and engaged?

  • Supply voltage at the control unit?

  • Fuse for the supply voltage ABS?

  • Wheel sensors ABS (fault memory)?

  • Diagnostic cables, nodes, connectors CAN-bus connection etc.?

  • Read error memory: which error is displayed?

  • Does the control unit come from your vehicle? Software status? Coding?

  • Wheel bearing / integral wheel?

If you do not see another error and your control unit is not working, we will try to solve the problem. In order to be able to limit the error, we need an exact error description and the printout of the current error memory. We would like to ask you not to return the control unit to us without prior consultation. Please contact us beforehand.
