Open fuel flap without switching ignition key off?

Anyone know how to get the fuel flap switch to work regardless of key position?

Thanks.

I don't think you can, without running a new feed to the solenoid, and as it is BCU controlled, that might be a bit of a job.

Pin 3 on the 8-way connector on the back of the BCU is the solenoid feed, but remember that the pulse to open the flap is not just 12V being turned on to the solenoid, it is time and current controlled.

why would you want to?

+1,don't see the need

it's piece of cake...the BCU only completes the earth path as to not let it open with engine running or alarm on but the solenoid gets feed from fuse F2 directly through the switch... you have to connect directly to eart the red/blue wire which goes from BCU to the solenoid, that's all...then it will open all the time when you push the switch... as a matter of fact IMO LR overcomplicated this thing by involving the BCU

Cheers, I'll give it a try. Over here during summer, no one wants to switch off the a/c for refilling when it's 49degs outside... All the petrol stations are full service....

So just to clarify - short pin 3 to pin 5 right?

which pins are you talking about...there are two wires to solenoid, a purple/red from switch and a red/blue from BCU, you have to cut the red/blue wire near the solenoid and connect it to body as the solenoid to have permannent earth not managed by the BCU...or if it seems easyer to you cut from BCU C0664 pin 3 and connect that to earth.

EDIT : just realised you spoke about pins of C0664, you have to cut the wire from pin 3 to not give earth backwards to BCU, and you can connect it to pin 5 yes

I saw that BCU C0664 pin 5 was earth, so though that bridging it to pin 3 would provide the earth?

Ha, think we were both typing at the same time... Got it - cheers

Finally got around to having a go, this afternoon.

Thanks, it works great. Now I can sit in the car, fat dumb & happy, while they fill it up...

But don't you want to stop the engine while they do it?

Nope - need the aircon nice and chilly... It's just the way they do it over here, so who am I to argue
