BMW 3 Diesel Won't Start: LIN Bus Communication Fault

I own a 2009 BMW 3 with a Diesel engine and 140,000 km on the clock. I'm experiencing an issue where the car won't start. I've encountered a LIN bus communication fault. I've already changed one glow plug as indicated by the scanner, replaced the module, and installed a new battery, which was needed anyway. I've also ordered a wiring loom in hopes of resolving the issue and have changed the crankshaft pulley and bolts. Has anyone experienced a similar problem or have any advice on what else I might try? Any help would be greatly appreciated.

A 2009 BMW 3 Diesel is experiencing a starting issue linked to a LIN bus communication fault. Despite replacing a glow plug, module, battery, and crankshaft pulley, the problem persists. A wiring loom has been ordered as a potential solution. It is suggested to check fuses and relays related to the starting system and LIN bus communication, as a blown fuse or faulty relay might be the cause.
