This E90 328i hit a deer on the highway…
…and the impact ripped the front passenger engine wiring harness out of the car.
What started as front-end damage quickly turned into one of the most involved electrical diagnostics jobs we’ve handled.
During diagnosis we discovered:
• Front engine harness ripped from the deer strike
• Aftermarket immobilizer + GPS tracker spliced into the CAS wiring
• Improper amplifier wiring for a line output converter
• K-CAN network failure caused by a failed JBE module
The immobilizer and tracker were removed, wiring was restored back to OEM configuration, and the JBE module was replaced and coded to bring the vehicle network back online.
Once the electrical backbone was restored we rebuilt the front end from the deer strike:
• G80 pre-LCI style headlights
• Passenger fog light + grille
• Splash shield + wheel liner
• Hood latch repair
• TPMS antenna replacement and programming
While the car was apart we also completed:
• Full brake service (Zimmermann + Akebono)
• Front passenger wheel hub + bearing
• Oil service (5W-40)
• Blower motor replacement
Interior upgrades included an Android head unit with Apple CarPlay / Android Auto and backup camera, along with door handle and interior clip repairs.
This project required deep BMW electrical diagnostics, network troubleshooting, wiring repair, module coding, and full front-end restoration.
Not every shop takes on work like this.
This is exactly what we specialize in.
Another BMW saved.
