X5 in trans safe made
Initially, the problem was a no start issue and after replacing the Ignition switch as well as the starter. The problem was unresolved. we bypassed the Ignition switch to get it started, but after that, the transmission went into fail Safe mode. The rear airbag Suspension system also stopped working at the same time as when the fail safe mode started. I'm trying to see if these 2 systems share a simular relay or module. Any thoughts or suggestions that can help me locate this electronics Grimlin would be really appreciated. Thanks again in advance. |

Welcome to the joys of putting your X5 into transport/line mode most likely.
After your bypass it has probably pissed off the EWS. What codes do you have (not generic P-codes) now? Sent from my SM-A528B using Tapatalk

The code that I think I need to address first is a transmission code for the neutral switch. any thoughts on how I can bench test this switch before I pull the Trigger on ordering a new non returnable part? I attached the scanner print out in case you wanted to take a look at that.

You’re welcome.
Actually, I should have made it clearer that the continuity test is between the positive pin and the four ‘L’ pins. ![]() Phil |

Well, after a lot of trouble shooting I'm still back at zero. I have replaced the transmission neutral switch. Twice and I still get a no start issue. I do not have a shift indicator light on the dash To show what gear the vehicle is in. Where do I go from here?

I'm getting transmission neutral safety switch code and there is no communication being logged for the transmission control unit.

Does key on run position show gear position on the dash (but very dim)? What actual code are you getting? e.g. 4e21 There are several possibilities, that I had before.... 1.Mechatronic gearshift is bad. 2. Safety interlock to ignition switch is bad. 3. Mechatronic Valvebody is not working (internal or external harness, reed switch is sending incorrect gear position) What scanner are you using and if it shows live data is it showing Transmission in agreement with gearshift position (all positions) note that the car doesn't have to be running for this test...
