Problem: No red light on Foxflash programmer bench box and switch, has happened to anyone?

Solution:

Light comes only when tool start reading, when it says keep ecu power on make sure switch is at 1, then press ok that’s when the light will come

How to Repair VW DCM6.2V No Start Issue on Foxflash

Problem: How do I read and write down a driver in a vw dcm6.2v with foxflash in boot mode, because after installing stage 1 (via OBD) the car does not start and I can’t bet anything?

Solution:

That situation usually comes from checksum handling or wrong patch area — DCM6.2V is picky.

If you can still read and connect to ecu, write original file, test if it starts.

If yes, then manually checksum the file and write it back. If it still causes problems solution is not good (bad file).

Foxflash don’t have bench or boot protocol for this ECU.

You can also take boot read and restore ecu.
