While configuring / pairing the bluetooth device on your computer, you need to specify a key for the device. The same key will apply for your mobile device also.

I just fixed that problem. The problem is loose resistors on the instrument cluster's he printed circuit board. It's four bigger resistors parallel to each other. Re solder them and you are set.

Try 0000

try 0000
