The BMW E70 is coming with turn signals don’t work and other functions like windows cannot go down issue. After first scanning, I’ve found there are several failures in dynamic control door. So next I’ll disassemble the FRM module and repair it with Xhorse VVDI Key Tool Plus Pad.

In the process, I’m going to use XDNP18 Solder-Free Adapter to read it out.

Connect adapter to FRM module &Key Tool Plus, let’s get start:

• Click “Write >> DATA-REPAIR” and select the file saved in step1

Writing completed.

Finally, I’m gonna disconnect and assemble the FRM back to vehicle for a check.
