I had a bad crankshaft position sensor, which I replaced. Once I replaced it, the vehicle went crazy about a day later. Here’s the symptoms: Brake, 4x4, and automatic transmission warning light all stay illuminated. The vehicle bucks and jerks, searches for gears as the RPM’s bounce all over. The battery light will flash when the RPM’s bounce. It has a new alternator and the battery is at 88% charged after being tested. Here’s the codes I had pulled: ECM: 2718 Crankshaft sensor: reference mark 3CD1 Crankshaft sensor: signal 279C Thermostat, map cooling: activation DSC: 5EB1 Steering angle sensor, supply 5F21 Engine management interface 5F41 Transmission control, limp-home operation Gearbox Control Module: 54C6 oil wear 55C4 No message from DSC 55C5 No message from engine management Central Body Module: total codes 11 4C passenger mirror internal error: timer watchdog 0D Power window open circuit jam protection strip lost or caling error EKS electronic driver’s door 0E Power window open circuit jam protection strip lost or caling error EKS electronic passenger door 0F Power window open circuit jam protection strip lost or caling error EKS electronic driver’s door behind 10 Power window open circuit jam protection strip lost or caling error EKS electronic passenger side behind 6B no answer passenger mirror 6A no answer switch block 6C no answer drivers mirror 33 wiper: is blocking or reset contact 5F driver mirror: potentiometer axel 2/4 3A Wiper: replay pump or wire for headlight cleaning system I looked at the plastic gear in the transfer case actuator, it was fine, no wear or missing teeth whatsoever. At this point I’m thinking something is shorted out. I’m at a total loss on this one. Any help would be appreciated. 2004 BMW X3 2.5i ---

I’m not a BMW guy buy any stretch of the imagination, but a lot of vehicles require a crank position variation learn after replacing a balancer, sensor or ECM??? ---

It’s probably something simple and dumb. From all of those things givin supply/no contact codes it seems you have something big unplugged, or maybe tripped a major fuse. Get pokin! ---

I took Benny’s advice and went through everything. The Crankshaft sensor bolt backed itself lose. The original bolt had locktite, where as the new bolt, which came with the sensor didn’t. With a little loctite and retightening, the transmission issue is gone for now, hopefully good. I’ll do a few drive cycles then have the codes pulled again. Adam, as for my next car, I’ve been looking at Porches 996 Carrera or a Lotus Elise, nothing new, but in the mid 2000’s. I won’t pick it up until next spring anyhow, so I have a lot of time to make a decision. Again thanks for the help. ---
