Question 1

How does a mail-in repair work?

Accepted Answer

You send us the faulty control unit, well packaged — ideally with a short description of the fault. Once it arrives, we run a diagnosis and get back to you with a firm assessment and a clear price. After your approval we carry out the repair and return the fully tested unit, usually within 48–72 hours.

Question 2

How much does a diagnosis cost?

Accepted Answer

The initial diagnosis is free of charge if you commission the repair. If no repair goes ahead, we only charge a fair flat diagnostic fee — we tell you the exact amount in advance.

Question 3

Do repairs come with a warranty?

Accepted Answer

Yes. Every repair is tested on our test benches and leaves the workshop with a warranty. We spell out the exact scope in your quote.

Question 4

Does the control unit need to be relearned after the repair?

Accepted Answer

In most cases, no — the unit stays coded to your vehicle and works immediately after installation (plug-and-play). When cloning, we transfer all data 1:1 to the replacement module.

Question 5

Can you erase crash data from any airbag control unit?

Accepted Answer

We support almost all manufacturers and models. Send us the part number of your unit — we will confirm promptly whether erasing is possible.

Question 6

Is chiptuning legal?

Accepted Answer

In Germany, performance upgrades must be registered or covered by a component approval (Teilegutachten); deactivating emissions-relevant systems (EGR, DPF, AdBlue) is permitted solely for export vehicles or motorsport use off public roads. We advise you transparently on the legal framework in advance.

Question 7

What do I need for a replacement key?

Accepted Answer

Your vehicle registration document (Fahrzeugschein), a valid ID and — if available — an existing key. If all keys are lost, making a new one is still possible in many cases; the turnaround depends on the vehicle model.

Question 8

Do you also work with workshops and dealers?

Accepted Answer

Yes — a large share of our customers are independent workshops and dealers. On request, we set up fixed trade terms and priority handling.
