Service bulletin 01146620306652

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

The quality of the auxiliary exhaust gas recirculation (EGR) cooler modules manufactured within a certain timeframe may be inadequate. The vacuum actuator diaphragm may have leaks. A faulty auxiliary EGR cooler will trigger a P310E fault. Faulty operation of the auxiliary EGR cooler can also trigger the P040B fault, but there is no issue with the temperature sensor.
