You would need custom firmware either one of the 3 modified by Josi.
3800
2760
1300
As long as its the modified one then it's ok
Please do not post duff information. It helps if the facts are confirmed first!
The modified firmwares are
NOT battery drain modified. They are modified to work with any unit be it a Skoda or VW unit so you don't get issues with MFSW etc.
You require the can gateway fix to be applied after installing the 276X firmware.
Neil,
Follow the tutorial i did. Install the 276X firmware first then put the Old can-gateway fix on after that. If you get any issues give me a shout.
