[F10 535i] DSC and Flexray Issues
Hi!
I have a 2012 F10 535i RWD and I’m experiencing a slight loss in power-steering, static speedometer, reduced engine and drivetrain output, as well as brake and ABS lights. The car drives, but the loss of power and comfort is incredibly noticible. In idrive I see these errors: ‘Chassis Stabilization Malfunction’, ‘Brake System: Drive Moderately’, ‘Passenger-Restraint System Malfunction’, and—when taking off in drive or reverse—‘Park Brake: Limited’. Attached are the BMW trouble codes that I pulled. From them, I have construed that the DSC is sending nonviable wheel-speed messages. I replaced the DSC’s fuses, and later, the rear wheel-speed sensors. The problem has persisted, and I suspect there may be an issue with a cable or connector being corroded or ruined, or an issue with the internal constitution of the module, itself. I spotted something that may be troublesome, but it seems that it is just external; exclusive to the cable wrap (See Image 6) I have checked both rear sensors, as that is conducive to their replacement, and I also checked the front left sensor while trying to take a look at the DSC module, itself. I am wondering if there is any way to get a better idea of where to look and/or how to fix this. I’m having trouble getting ahold of a viable ISTA+ download, so that makes things a little trickier for me. I will also add that I recently had a bit of work done (replaced differential, left-rear cv axle, spark plugs, ignition coils, oil change) In November, the axle gave out and broke part of the differential. I had the differential’s broken area welded, and the axle replaced. That shop didn’t do a good job and it broke a week later. I had replaced the differential with a brand new one in mid-February, as well as the axle (because the last shop didn’t use the right one lmao). I got these errors when my diff gave out, and they stayed until I took it to get repaired again. They came back about a week later😅. I’ve been trying to figure it out with my own research, but I feel like it’s time to reach out to see if anyone has any ideas. Thank you in advance for any assistance! |
