Confirmed Fix:
Replaced Engine and Programmed Powertrain Control Module (PCM)
Problem Description:
Vehicle came to the shop for an oil and filter service. Found the oil to be milky brown in color. It had a very strong smell of fuel and it was about 2 to 3 qts. over-full.
Located a TSB related to fuel in the oil for customers who drive only short distances and particularly in extremely cold temperatures (20 degrees or less). It states to have the PCM reprogrammed for the fuel injectors in cold temperatures and to change the oil and filter.
We changed the oil and filter and reflashed the PCM but in this particular case, the vehicle exhibited significant engine wear and was blowing while smoke from the exhaust on cold starts and during acceleration before the engine was at operating temperature.
Found the cylinder walls prematurely worn due to an excessive amount fuel in the oil for a significant amount of time.
It was necessary to replace the engine assembly.

Confirmed Fix:
Repaired Ride Control Wiring
Problem Description:
The complaint was level control system malfunction displayed in the iDrive. Scanned the Electronic Height Control (EHC) and found two codes 5F94 Solenoid valve rear left and 5F95 Solenoid valve rear right. These codes are not readily found and the wiring diagrams don't specifically list these two solenoids. They are built into the air pump on this particular BMW. Removed the the right side undercover and exposed the pump. Immediately acorns and dog food fell out of the cover. Tested for power on the Brown wire and found none. Traced the wire up the wheel well cover and found the chewed wires. Repaired with a crimp and sealed the connectors and all is OK.

Confirmed Fix:
Repaired Heated Oxygen Sensor (HO2S) Bank 1 Sensor 2 (B1S2) Wiring
Problem Description:
Trouble codes P0102 Mass Air Flow Circuit Signal Low and P0443 EVAP Purge Control Circuit Fault are present. The IGN 1 fuse 21 in the under hood fuse center is blown. Checked the circuit wiring to see which components are fed with fuse 21 and unplugged the Mass Air Flow (MAF) sensor, Evaporative Emissions (EVAP) purge solenoid and the upstream and downstream O2 sensors. Installed a new fuse 21 and it blew out immediately. Traced wiring and found a short to ground on the Pink wire going to the downstream oxygen sensor. The location of the short was at the transmission to engine bracket on the back side of the oil pan, roughly 4-5 inches from the oil level switch and towards the rear O2 sensor. Repaired the wiring, installed the fuse and cleared the codes. All problems have been repaired.

Confirmed Fix:
Replaced Engine and Replaced Intake Manifold
Problem Description:
This vehicle came to the shop with a noise in the engine and a miss on cylinders #5 and #7. Checked the spark plugs on these two cylinders and they were beat up pretty bad. There was 0 compression on #5 and the compression was going past the piston into the crankcase. The engine was replaced at this point. Now the remanufactured engine has a tick or knock like a bad lifter at idle. If the intake manifold runner was pressed down, the noise went away. Replace the intake manifold. Cut the old intake apart on the original engine and the back bushing for the manifold was not there. The engine ate it and there was ΒΌ inch of slack in the runner shaft.
