OBDSTAR P50 battery reset upgrade V30.06 has been released to support Audi BMS 8R0915233, 8R0915591 crash record erase and repair by bench. No need to disassemble or read the chip, no risk and difficulty, which can save a lot of maintenance costs. This is a tutorial on how to perform the new function step by step.
In Audi A6, A8 and Q5 hybrids, the hybrid battery management unit(BMS) disconnects and logs a P1609 fault code when a crash occurs: (!!! Crash shut-down activated!!!), resulting in the vehicle not starting.
At present, only a few auto electronic repair professionals through the brush firmware or open the cover through the programmer to repair. This way is high fees, risky and only support some models. Thus, OBDSTAR releases free upgrade P50 battery module repair function again!
