Additional information

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:

Phone: 040 - 25 30 66 55 Email: service@aic-germany.de

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.

When replacing brakes, the chassis components must always be checked with regard to clearance and the wheel hub with regard to wobble, and the appropriate documentation must be produced.

If the vehicle is no longer in its original condition due to tuning work such as wheel accessories and tracking plates, the entitlement to make warranty claims is lost due to third-party work. The same warranty claims are lost if the vehicle is used for motor sports or similar events.
