Tried to put the 07 VDP into test mode, like the 04.
To my surprise nothing happened W T F.
With door open, or closed, no luck.
Is there another way for the later model cars?
Trying to compare readings with proper working fuel senders.
Since both of the 04's fuel sender's replacement.
The reading is no longer going to empty when filled.
But is only reading 3/4, when the tank is full.
It does drop with the level, so thats much improved.

Was looking to compare numbers, of the 07 test mode.
