❓ Frequently asked questions
Do I need this kit for MD1 / MG1 with the ECU Master?
Yes. OBDSTAR requires the C4-06 adapter to unlock locked Bosch MD1 / MG1, in BOOT mode. The Standard is enough.
Do I need to remove the steering column lock for a proximity-key MQB?
With the MQB Collector in the Full kit, no: the data goes through the dashboard connector. Without it, you have to remove the ELV and read it with the MP001 and the C4-06.
Which engine ECUs are not supported for MQB?
According to OBDSTAR: MED17.1.27, MED17.1.62, MED17.16, MG1CS001, MG1CS011, MG1CS111 and SIMOS16. SIMOS18 cannot be read with the dedicated cables.
