Frequently asked questions (FAQ)

Yes, we absolutely need the requested information in our repair order. We have structured this order in such a way that we can start repairing the control unit immediately upon receipt of the order and there are no queries or time delays. Devices that are received without a repair order and error description will only be processed by us after all open questions have been clarified. This results in a large delay and effort.

Depending on the vehicle type and equipment, the devices are installed in different places. Control units should only be removed and installed by an appropriate specialist. If you do not know exactly where your device is located in the vehicle, please contact a knowledgeable person. (Your workshop) Unfortunately, we cannot give general instructions for all vehicles and types at this point.

Please refrain from attempting to repair your control unit yourself. Under certain circumstances, the device can be so damaged that it is no longer possible for us to repair it. Please also do not use any contact spray or similar that you spray into the device. This too can render the device irreparable. If we determine that improper opening or repair attempts have been made to your control unit and this results in considerable additional work for us to repair the control unit, we will invoice you for this. If a device has already been opened, the chances of it being repaired decrease drastically.

In the vehicles, many errors are noticeable when various warning lamps light up. Various malfunctions can also occur. The errors can occur permanently, sporadically or depending on the temperature. It is always important to first query the vehicle's error memory with a suitable diagnostic device and localize the error. The error texts can vary depending on the diagnostic device used; a combination is also possible. The repair solutions and errors we offer on our website are of course only a small selection. It is important that you send us an exact error description, the error code and our repair order. Only then is a repair economically feasible.

Control units should only be installed by an appropriate specialist. The working method specified by the manufacturer must be observed. Unfortunately, we cannot give general instructions for all vehicles and types at this point. If you receive special instructions or supplements from us that are suitable for the device, please use them as well.

If your control unit is not working, there can be several reasons. We have checked and repaired your control unit. If we noticed during our incoming inspection that your control unit was working, we would have informed you immediately and only charged a handling fee. Therefore, there is probably another fault in your vehicle. It is now important to check everything again.

Therefore, please check the following in the event of a malfunction:

-Are all plug connections restored and engaged?

-Supply voltage at the control unit?

-Fuse for the supply voltage

-Read error memory: which error is displayed?

-Does the control unit come from your vehicle? software status? coding?

If you don't see any other errors and your control unit doesn't work, we'll be happy to try to solve the problem. In order to be able to localize the error, we need an exact description of the error and a printout of the current error memory. We would like to ask you not to remove the control unit and send it back to us without prior agreement. Please contact us beforehand.

If only the control unit was removed during removal, but the valve block with brake lines remains in the vehicle, the brake system (without ABS) is conditionally operational. Please note, however, that the ABS or ESP functions are not available. Likewise, the braking force distribution cannot be optimally controlled in some vehicles. As a result, the full braking force cannot be used. The rear wheels can lock before the front wheels under heavy braking. This makes the vehicle very difficult to control. We recommend protecting the valve block and the plugs from dirt and only making the most necessary trips. Please also note that other errors can occur in the vehicle for which we assume no liability. In principle, driving without an ABS system is not recommended. Every driver acts at his own risk. If the valve block has been removed and the brake lines removed, driving with the vehicle is generally not possible!

No, your control unit will work again immediately after installation. However, this only applies if your control unit comes from your vehicle. If it comes from another vehicle, it must be encoded. However, you should delete the error memory after successful repair.

We test every device before repairing it. If your device works and we don't see any faults, we will charge for our testing effort and send your control unit back to you.

The repair time for standard devices is usually around 2-3 working days (depending on the number of repairs). After the repair has been completed, you will receive your device back immediately together with the invoice. You don't need to make an appointment with us: we repair when the devices arrive. We can also treat your repair order preferentially. We offer you the option of "express repair" and thus guarantee you a very fast repair time of 1 working day. We calculate this service depending on the device type. You can make a selection for this in the repair order. On our website we announce important dates such as holidays or similar about 2 weeks in advance. All information is subject to change and applies to shipping within Germany.

-No repair order / no customer data / no error information etc.

-Transport damage / shipping problems

- By trying the repair yourself

- Due to water damage / accidental damage etc.

- Due to insufficient error information / error code

For control units that do not show any errors in our test, we charge a test fee plus VAT and shipping.

Even if we cannot find a fault or cannot repair it for an unknown reason, the costs for the following time expenditure must be paid:

-Unpacking/packing the device

-Inclusion in our system

-Check by the technician

-Communication with customers

-Return

In this case, we calculate our handling fee plus shipping costs and VAT.

Possibly also test costs on a vehicle.

If your device cannot be repaired, we will try to offer you a replacement device from our warehouse or organize it through our network. If this is not possible, we will try to get a new device for you at favorable conditions. This is all done in consultation with you. We try to help you.

Of course, you can also hand in your device to us personally and pick it up again. In this case, we ask that you make an appointment in advance by phone or email.

If you would like us to take over the complete removal and installation of the control unit in our master workshop, please contact us by telephone and make an appointment.

No, this is technically not possible and also contradicts our business practices.
