How to Solve Foxflash DQ250 Gearbox Read Problem

Problem: Foxflash failed to read VW DQ250 gearbox from Golf6 GTi on bench.
Error no Flash, no Eeprom, no Backup?

Solution:Your voltage is too low.

You’re running way under 12v and doing DSG gearbox. Add 13volts and some amps. Then try again.

On these 02E Foxflash works better than PCMflash. You need OBD to DSG socket cable and manual power switching. Or use godiag ggt107 gearbox adapter.
