Processing repairs

In-house processing

You are welcome to bring your vehicle to our workshop in Düren (North Rhine-Westphalia, Germany). We will take care of removal and installation on-site.[*] Please contact us in advance to discuss repairs on site and arrange an appointment. Repairs of combined instruments and satellite navigation units usually take no longer than between one and two hours. Please query the duration of repairs for control units and other electronic components.

We have provided a customer lounge with a coffee machine, television and magazines. Alternatively you may also use our convenient mail order service for repairs.

Mail order services

Send your parcel with the parcel service of your choice.

Please remember to attach the Repair form.

In most cases, we repair received electronic components on the same day.[**]
We will also return the units on the same day. As a rule, parcels are shipped for between one and two working days.
Payment is conveniently collected on delivery, i.e. you pay the parcel service agent in cash at your front door.

We use UPS as our shipping agent.

Packaging tips

We recommend sending parcels as regular parcels instead of small parcels. Usually small parcels are not insured and longer delivery terms apply. Make sure to pack the unit carefully as it is a sensitive electronics component that is very susceptible to damage. We also recommend using a carton that is larger than the component (5 cm extra space on each side), wrap the component in bubble wrap and fill the remaining space with packaging materials (e.g. polystyrene chips).
