Hi.

I'm currently restoring a 2004 Lupo to be my daughter's first car, and I've noticed that whenever I open either of the doors (driver or passenger side), the fuel pump briefly activates. It seems like a feature similar to the automatic pre-glow function when opening the door on a T4 with an ABL engine.

Can this feature be disabled using a VAG 1551 device, or do I need to obtain a wiring diagram and manually resolve it?

Thank you, Rüdi.

Hello,

To the best of my knowledge, this cannot be solved through coding. As always in such cases, a full system scan is absolutely necessary to determine which control units are involved.

Best regards, Rainer.

Hello everyone!

Alternatively, and quite unconventionally, you could remove the fuse or relay for the fuel pump. icon_cool.gif
There's probably a mistake somewhere, but it will definitely be easier to delete than accidentally changing something due to coding errors.

Best regards from Munich!

Well, it doesn't really matter now. My car, "Schüsselchen," just passed the new technical inspection, so hopefully I won't have to worry about it for a while.

Sure, no problem. Here's the translation:

"Thank you very much."

Rüdi.
