N323 - Diesel Exhaust Fluid (DEF) Injector Wiring Under Tension

Thursday, December 3, 2020
by Oliveston Ltd

Dear Colleagues

A potential concern has been identified on specific vehicles within the above Vehicle Identification Number (VIN) range.

Tension in the wiring harness for the Diesel Exhaust Fluid (DEF) injector could cause the wiring to break at the DEF injector connector. Diagnostic Trouble Code (DTC) P2047-13 could be set in the Powertrain Control Module (PCM) as a result.

 

Action to be taken

Unsold vehicles must be repaired prior to handover of the vehicle for retail sale.

At the next opportunity, you are requested to repair the vehicle.
