Our products are usually delivered without installation instructions. Installation may only be carried out by trained specialist technicians. Products supplied by us are exclusively intended for proper and appropriate use. The warranty is void in the event of improper, contrary to the intended purpose or unsuitable application or use.

For electronic items that leave fault memory entries, it is essential to submit fault memory logs in the event of a claim. This consequently concerns all electronic items that are detected, monitored and controlled by the engine control unit, such as sensors of all kinds (e.g. NOX sensors, ABS sensors), mass airflow sensors, airbag slip rings, headlamp levelling control units, throttle valves, lambda sensors or EGR modules.

If you encounter difficulties during a repair (troubleshooting max. 1 hr.), please contact technical support at:

This often avoids extensive troubleshooting that is disproportionate to normal repair times.

The following applies to complaints: The more complete the processes are submitted, the faster they can be processed.

Complete documentation includes the warranty application (incl. KBA no., chassis no., first registration, engine code, mileage), first and second installation invoice, fault memory log, guided troubleshooting and, if applicable, pictures. Incomplete documentation may result in rejection of the claim.

Technically it is possible to combine ATE Ceramic brake pads with the PowerDisc or with perforated brake discs. The brak ing power with such a pairing is the same as with an origina l ATE brake pad or OE brake pad. However, when the two compo nents interact they can generate more noise in braking. ATE Ceramic brake pads were developed for comfort-oriented drive rs. We therefore recommend using them with normal brake disc s, i.e. smooth ones.

For vehicles without ABS, a PowerDisc can be used on the rea r axle only if there is one on the front axle. The General Operating Permit (ABE) for the PowerDisc applies to operation on German roads in accordance with the German Road Traffic Registration Ordinance (StVZO). Other countries may require additional type approvals for use on roads.
