Identifying the Root Cause of Your Battery Fault
A high-voltage battery fault in your Tesla Model 3 can manifest as a variety of issues, from reduced range to a completely immobilized vehicle. Our **mobile diagnostics service** comes to your location to perform an expert, on-site assessment. We use advanced diagnostic tools to pinpoint the exact source of the problem, saving you from a costly and time-consuming tow to a service centre for a preliminary check.
Common Battery-Related Issues We Diagnose:
Battery Management System (BMS) Errors
The BMS is the brain of the battery pack. When it detects an issue, it generates a fault code that can limit your car's performance or shut it down. We can read and interpret these specific error codes (e.g., BMS_f003) to understand the underlying problem.
Failing 12V Battery
A dead 12V battery is the most common reason for a "bricked" Tesla. It's often mistaken for a high-voltage issue. We can test your 12V battery and replace it on-site, a quick fix that avoids a complex and expensive repair.
Reduced Range & Unexpected Drain
If you are experiencing a sudden or significant drop in your car's range, we can run diagnostics to check for cell imbalance or other issues within the battery pack that may be causing the degradation.
Overheating or Thermal Management Faults
Issues with the battery's cooling system can lead to a thermal management warning. Our diagnostics can identify if the cooling pumps, sensors, or other components are malfunctioning, a necessary step before a repair can begin.
Important: Our service is for on-site diagnostics only. Physical repairs to the high-voltage battery, such as replacing a faulty cell module, must be performed in a specialized workshop under controlled conditions. We will provide a full report and an honest assessment of whether the issue can be fixed remotely or if it requires a tow to a specialist facility.
