06 3.0i-Trifecta lights- abs,brake,4x4 with Check Engine and Trans Fail Safe.
For context, the trans failsafe with the acompanied lights instantly turn on even before I turn the car on. I'll switch it to run and get all the lights and trans fail safe instantly. The check engine with the basic coder reader said P0600(Serial Communication Link). Pasoft said (Signal can EGS timeout elapsed). What's interesting is, PASoft does not detect the electronic gearbox module. In INPA, I had 217 Timeout CAN-Botschaft EGS1 with some irrelevant o2 heater sensor errors which I will deal with later. In INPA, I found 5 errors in the transmission section. 55C4 CAN_MESSAGE_DSC1, D61E CAN_TIMEOUT_EGS1_SMG1, 5208 Stellmotor Verkabelung, 54C8 Klassierwiderstand am Stellmotor. I did hear a weird rattle on the driver's side, so I was inclined to change the actuator. Once I changed it the noise went away but the same errors were still present, I tried to clear them but INPA couldn't. So I decided to go deeper. I bought a 30$ EGS off eBay with the same numbers except for the VIN. I heard that if you have the same model you don't need to reprogram it. When I installed it, the same errors appeared. basically, nothing changed at all. Going to be returning it. I checked all the connections I could for the transmission, I went under the car and unplugged the sphere-looking cable, and checked both the connecter and socket both were dry and clean. I did see a square-looking connecter that was toward the engine side, it was oily, but the inside was clean and the cable was also clean. No change I checked the ABS Connector to make sure it was also ok. that was also clean. I tried the trick of unplugging the ABS which would disable the speed gauge and other stuff, but I wanted to see if the trans-fail-safe would disappear, it didn't make a difference, instant trans fail-safe. I checked all fuses for the transmission(electric gearbox), abs, and transfer case. All were fine and I switched them with replacements anyway to make sure, but still nothing. I went to a BMW indy in my area and they were busy but were able to try and scan it. their maxi scan couldn't find the transmission module either. My final step is going to the dealer on Monday in hopes they find something. If anyone has anything I could try that I haven't already please chime in. EDIT: Forgot to mention, I changed my battery with my 3-year warranty because I heard if the voltage is low it will mess with modules. My alternator should be fine since while the engine is running at idle it's at 14.0 v and If I drive it doesn't drop lower than 13.8. The battery change did nothing as well. FIXED: I posted a reply below with all the details, but my o2 wires were melted together causing a 30A fuse to blow disabling the EGS. I fixed the melted wires by separating them and putting a new fuse in. The car is running perfectly again all lights are gone. I linked the thread below. https://www.bimmerforums.com/forum/s...EGS-a-solution Last edited by Optllizer; 10-23-2022 at 04:27 PM. |

With INPA check the connection and codes individually on all CAN-bus modules and tell us what they show.
DME, EGS, DSC, VTG, LWS (steering angle sensor)

This is because facelift has DXC8 module, not 5.7 like on pre-facelift.

This morning I did a little more research and stumbled upon this thread. My O2 Sensors codes were actually very important in figuring out why my X5 was having transmission issues.
https://www.bimmerforums.com/forum/s...EGS-a-solution TLDR; He stated that his o2 sensor wires got melted together causing a 30A fuse in the black fuse box in the waterproof box on the passager side of the engine bay to blow. So I checked the same fuse in the same location and that fuse was blown. I put a new 30A fuse in and it broke again. So I went through all the O2 wires and found the area where they melted together. I separated all the wires and put a new fuse in. Started the car and it was working like it was before all the lights came on. Car is driving like a dream again. |
