Warranty Parktronic Sensor Repairs

SERVICE INFORMATION

An increased number of Parktronic (PTS) sensors are currently being replaced under warrant. The returned sensors display external damage at the impact absorber (painted part of sensor) caused by stones, parking mishaps, etc.

NOTE: Should a fault code be stored in the Parktronic (PTS) control unit (N62) and such damage is evident, the sensor malfunction was clearly the result of external causes and cannot be reimbursed under warranty.

In cases where the following fault code texts appear together with external damage, warranty claims will be debited as of repair date July 3, 2003. The customer is responsible in such cases.

A42b1 (Left outer sensor, front bumper): Sensor is defective
A42b2 (Center left sensor, front bumper): Sensor is defective
A42b3 (Left inner sensor, front bumper): Sensor is defective
A42b4 (Right inner sensor, front bumper): Sensor is defective
A42b5 (Center right sensor, front bumper): Sensor is defective

A43b9 (Left inner sensor, rear bumper): Sensor is defective
A43b10 (Left outer sensor, rear bumper): Sensor is defective

In cases where a complaint is reported and the following fault code text is registered, first check the connector and the line. If no fault is evident on the connector/line and the sensor shows external damage, the customer is responsible as of repair date July 3, 2003.
