You are welcome to bring your vehicle to our workshop in Düren (North Rhine-Westphalia, Germany).

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 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.
