DODGE

RAM DEF DEFECT

This bulletin applies to 2014-2015 Dodge RAM 2500 and 3500 trucks equipped with a diesel engine. The DEF level sensor might have a manufacturing defect. A MIL may be illuminated. DTCs P203B (reductant level sensor circuit performance), P203C (diesel exhaust uid..reductant level sensor circuit low) and/or P203D (reductant level sensor circuit high) may be stored.

The DEF system uses a complex radio frequency type level sensor to detect the amount of uid present in the DEF tank. As the uid level in the tank decreases, the level sensor becomes exposed to air which alters the signal sent out by the sensor. The sensor translates the signal change into a uid level and busses the information to the instrument panel cluster via the dosing control unit (DCU). A manufacturing defect in the level sensor may have occurred. Replace the DEF pump assembly and ensure that the DEF tank is approximately ½ full. Using WiTECH, perform a DEF reductant doser pump prime override test a total of 10 times to ensure that the DEF pump has been su ciently primed and that all air has been purged from the pump and lter. Turn the ignition key on and ensure the DEF level gauge is reading properly.

The new module kit is available as P/N 68192659AC. LINCOLN

ROUGH IDLE AFTER HOT MKT RESTART

Some 2013-2014 Lincoln MKT vehicles equipped with a 3.5L GTDI engine and built before June 1, 2014, might exhibit a rough idle and/or DTC P0087 after a hot engine restart. Reprogram the PCM to the latest calibration using IDS release 90.03 and higher. Files are available at www.motorcraft.com.

BMW

STALLS DUE TO FUSE

This bulletin applies to 2015 and later BMW 328i vehicles, 2 series, 3 series and 4 series vehicles. The engine might stall right after starting and/or the engine cannot be restarted. One of the following faults will be stored in the DME: FC 118033 (gasoline engines) or FC 2BAB00 (diesel engines). The power supply fuse for the fuel pump control electronics (EKPS) can fail due to an internal control module problem. Check the fuse for the EKPS, located in the rear fuse carrier. If the fuse is found open or faulty, then check the part number of the EKPS control module. If P/N 16 14 7 447 895 or 16 14 7 450 992 is installed, then the fuse and the EKPS control module need to be replaced together. If the fuse is not faulty, work through the applicable test plan for the fault stored.

CHEVROLET

BAD EXPRESS PUMP

This bulletin applies to 2012-2016 Chevy Express Cutaway vehicles equipped with a 6.0L gaseous dedicated LPG system three-tank con guration fuel system. These vehicles may experience an inoperative fuel pump leading to a no-start or stall without warning. GM has decided to conduct a voluntary emission recall involving certain vehicles. The fuel pump is to be replaced with a new design, available as P/N 23373813.
