Service bulletin PB-S29942-2019-0

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Volvo Car USA LLC and Volvo Car of Canada Ltd (Volvo) on behalf of Volvo Car Corporation, have decided to launch Service Action S29942 on certain model year 2019 XC40 vehicles. Volvo has identified that the catalytic converter diagnosis is not running as often as required. This condition does not affect vehicle drivability nor will it inhibit the OBDII system from monitoring, detecting and subsequently storing a corresponding diagnostic trouble code in system memory. Please note that there are no customer symptoms associated with this issue and vehicle drivability is not affected. The corrective action is to perform a total upgrade. Service Action S29942 affects 21,607 vehicles in the U.S. and 2,326 in Canada.
