Xhorse vvdi key tool plus read Audi A3 2014 MQB instrument cluster immo data and program all keys lost successfully using the MQB solder free adapter.
That board cannot be done by obd. I cannot enter service Mode because all keys lost. I need the key learn in the car for enter service Mode. Or i can send data of 01 engine and 17 instrument cluster for calc immo data and sync data but isn’t more expensive. If i read the cluster with vvdi key tool plus (as in the photos) with the file vvdi send immo data, only pay for the sync file. Program key the work it’s done.
These MQB adapters in my opinion are fast, safe. Works fine.
