This is the next-generation HVAC Controller Module used in Tesla Roadster 2.x. Located under the hood and exposed to the elements, this part was originally manufactured by Eberspächer UK. This sub-assembly commands the vehicle’s air-conditioning and heater systems and participates in the Roadster’s pre-charge interlock loop.
Failure of this module can trigger BSM error alerts, HV isolation faults, charging lockout, or even a complete vehicle shutdown. These units have been out of production for years. With a limited global owner base and dwindling OEM stock, replacements are often harvested from donor cars—parts that are aging and typically burdened with deferred maintenance.
We have fully reverse engineered the 2.x HVAC controller and provide comprehensive component-level repair and rebuild services. Our tenured Electronics Engineers service these boards in-house—diagnosing down to individual semiconductors, relays, capacitors, connectors, and thermal interfaces—while addressing known engineering weaknesses to enhance reliability beyond the original design.
Each controller is disassembled, cleaned, and bench-tested; failure points are corrected, interlock/charging behavior is validated, and the unit is re-assembled and verified under load in our electronics lab. The result is a restored module that supports safe charging, proper HVAC control, and robust isolation performance.
If your Roadster 2.x presents HVAC faults, isolation warnings, BSM alerts, or refuses to charge, this controller may be the cause. With limited replacements available, professional component-level rebuilding is the practical, durable solution.
