Been on the VXON forum and on there, for the insignia, it states that when a regen is taking place the rear demister kicks in. This allows them to add an LED to the circuit and show when a regen is taking place. Anyone know if the same happens on the antara (2.2)? Migth be a handy thing to have.
Ended up buying a different ELM327 and OPL DPF Monitor Lite on android play store. Works a charm - shows the DPF temp, the miles/kms since the last regen and the soot %. Needs a decent elm327 though, the cheaper ones from china are not fully compatible. I went for the iCarPro vgate Nero Bluetooth3.0 OBD2 Code Reader. (about £16 I think)
