I think i did something Stupid.

I left the Ignition key in during fillup. The ignition wasn't on - it was just in the slot. My Fuel gauge still read the same fuel - even though i have a full tank.

Is there something that needs to be reset via VAG-COM???

Thanks

 

leaving the key in doesn't effect the reading chances are you have a stuck sender/needle, give the dash a knock see if the needle moves other wise its a stuck/worn sender unit in the tank

 

Discnnected the battery.

Soon as i connected the battery - fuel gauge went straight up DIS read 400miles.....

Thanks guys - Lets remember not to leave keys in while fueling in future even if it is the OFF position - CANBUS is still active in the car!!
