Do you tried sleep mode or better a test drive ?
Usually need move the wheels after VTG it’s red.

this is ATC700 or ATC35/L?

usually not a real problem. just let the car go to sleep on ATC700. sometimes liquid spill into control unit next to battery damages this control unit.

Its a verry common issue remove battery cable for 30 minutes and connect then all will be back to normal

Yes, tried battery sleep. Driving 30 minutes. Battery removing for 6 hours.

I had this problem very often and battery reset always helped. Also new VTG software can fix this problem in future.
If battery reset and test drive didn't work just check supply. Maybe it's just a stupid coincidence

Just in case, if using K-DCAN with ISTA, make sure you're on 1 or 2ms in Device Manager. The default 16ms is not ideal.

If not using K-DCAN, ignore and hopefully it's not a broken module.

it is VTG issue, only on facelift E70, E71!
VTG defective! If you remove battery but not erasing errors all dashboard will be ok, if try to erase errors VTG becomes RED.
Update with ista wont help.

Just remove battery ,put it back, but not erase errors after!

Tries on other e70 now too. Did the same but resetting ews solved the problem. So after resetting ews vtg came back on both cars.

Maybe this will help someone.
Problem solved.
