Tesla Diagnostic Report

The vehicle was booked in after the customer noted a tesla reduced range message on the dash and inability to charge correctly. Our diagnostic workflow included a full fault-code scan, inspection of the high-voltage battery pack and all associated modules, as well as serial-data logging of battery management board status. Through this process, we identified that the BMB boards were damaged—this was the root cause of the range drop and charging issues.

Tesla Repairs

Once the damage was confirmed, the repair work involved removing the high-voltage battery pack, replacing the faulty BMB boards, cleaning and preparing the module environment, reinstalling the pack, and performing all necessary resets and system checks. After refit, the vehicle was validated to accept charge again and range was confirmed.

Resolution

Following the repairs, the tesla reduced range message condition was resolved: the vehicle accepted full charge, range returned closer to expected values, all warning messages cleared, and the customer regained confidence in their Tesla’s performance and battery health.
“If you’ve had the stress of a HV Battery Failure and the Manufacturer is pricing a Full Replacement at £15k to £20k, you really need to speak to these guys. Matt Copp was amazing. I chose them over another EV Company because Matt called me directly from an enquiry I made and talked me through the whole process and likely costs. He arranged for the car to be collected and kept me informed every step of the way. I’ve now picked up my car for the costs he quoted and am delighted that it’s back on the road for a fraction of the cost of a whole new battery. I can’t thank Matt enough, he’s saved me from scrapping my car and I can’t recommend these guys highly enough. Superb..”
