Confirmed Fix:
Repaired Coolant Hose and Repaired Keyless Entry Control Unit Wiring and Replaced Fuse(s)
 
Problem Description:
The dash lights, dome lamps and key fob are all inoperative. Found the dome lamp fuse located under hood and shorted to ground. Traced the issue to the batt+ circuit for the keyless entry module. About two feet down from the keyless module (at the right rear of the vehicle), there is a splice/bus connector with power and ground circuits. It is located right under the rear heater core lines. The rear heater core lines were leaking on the connector shorting the power circuits to ground. Replaced the lines and repaired the connector, which was melted. All problems solved.

Confirmed Fix:
Replaced Auxiliary Coolant Fan
 
Problem Description:
Found the auxiliary cooling fan to be inoperative. Tested square wave signal to fan control (on the back of the fan motor). NHTSA safety recall 12E02900 will require the dealer to replace the fan assembly if it is the one that has been identified as the defective one. You can read the number on the fan shroud to compare it to the one in the recall. It is visible on the passenger side of the vehicle just under the bumper and beside a BMW emblem. According to the recall, some of these cars have caught on fire due the after-run of 11 minutes that is programmed into the fan strategy.

Confirmed Fix:
Tightened Upper Control Arm Bolts
 
Problem Description:
Have someone turn the steering wheel left to right in Park with the emergency brake applied. Check it on a rough concrete surface and you may have to lower the pressure in the tires to get enough friction to allow the arm to pop (would not make noise in the shop on slick concrete) and grab the upper control arm and feel for a popping noise or sensation. If the noise/vibration is felt, return to the lift and tighten the upper control arm bolts. A front end alignment may be necessary.

Confirmed Fix:
Repaired High Speed (HS) Controller Area Network (CAN) Wiring
 
Problem Description:
The truck was towed to the shop as a no start/no crank condition. Scanned the vehicle and found no communication with the Powertrain Control Module (PCM). Checked all fuses and they were OK. Checked the power and grounds to the PCM. Scanned the Passive Anti-Theft System (PATS) and found that the PCM was not returning the challenge message for the PATS causing the vehicle to not start. Checked the high speed data lines from the PCM to the Data Link Connector (DLC) Pins 68 and 69 on the PCM. Found positive high speed bus line pin 69 had over 13 ohms of resistance where the negative bus line was around 0.2 ohms. Followed the wire from the DLC and after a lot of time, found the wire was damaged underneath the air box. The wire must have been cut from the factory and ended up corroding through causing a poor connection. Repaired the bad wire using solder and a good heat shrink. The engine fired up right away.
