Hi all!
Little strange one on a 2011 VW Caddy today.
No start, instrument cluster dead, only lighting up when you open the door. Did an autoscan and although it show Engine OK and ABS OK, Airbag OK etc I can't communicate with them. In other modules such as the gateway (but not only this module), I try to delete the fault codes and it just says the module does not approve the request or words to that effect. There are some low voltage codes stored but I know the voltage is ok at the time of testing and the relevant controllers have good 12v but still no go. The vehicle has had some battery issues in the recent past. Any ideas?

First verify battery and battery cables are to factory design... no crappy battery with rotted cables and loose clamps.

Lets poke sticks at the airbag module since it is off line... it get powered by fuse SC15. Fuse SC15 gets powered by the terminal 15 J329 relay. To that end, when you turn the ignition on, does fuse SC15 have power? If not, locate and inspect J329 relay.
