Frequently asked questions
What should I put in my enquiry?
Vehicle, year, what exactly happens and when the fault occurs. Fault codes, the control unit’s part number and what has already been done also help.
Do I need to know which part is faulty?
No. Just describe the problem – we work out the rest through diagnostics and testing.
How much does the repair cost?
That depends on the unit and the fault. After testing we tell you the price – we only repair with your approval.
Can I send the control unit in?
Yes. After a quick chat, by DHL to AEZ, Werkstraße 4, 46240 Bottrop, Germany. Packing tips and the shipping note to fill in are on the “Sending in a control unit” page.
Do you only work on Mercedes-Benz?
Our focus is Mercedes-Benz. For other makes, just ask with the vehicle and part number – we’ll tell you honestly whether we can help.
