Hey go2guy, was the backlight on when it went blank? I would try reflashing it at this point, but it is easy for me to say (and do). You can sase it back if you want me to do that, pm me if you need the address. I'll put the unit through it's paces while it is here.
Eddles, so far it is a custom job to get diesel feedback. The
audi/vw folks have had considerable luck using a signal coming from the ECU and on a TDI as well, and Another guy got it pretty much working on a
pugeot HDI car . But those are the only diesels that I know of.
