To be honest, I'm not keen, as I don't want to mess with the connectors or short out the fuse (due to clumsiness). I'm selling my van soon and I have a whole heap of other jobs to do to get it ready for sale. The current used must be very very small, as even when fully lit LEDs don't use much. I have often left my van for weeks between uses without flattening the battery, but that is with the interior lights manually switched off.

Would you be happy to measure current flow through your interior leds when they are aglow Greg?

That's very interesting Greg, thanks :o)
The faint glow can only be down to
electricity flow through the circuit. If you refit tungsten bulbs I daresay you'll get a flat battery after a few days. |

BTW I've been running LED interior lights in my van for over 10 years with no problems. They must be better quality than the one I put in the cargo bay of my Golf R wagon, it has started to intermittently fail after only 2 years :(
The only oddity I've noticed in the van is they give a faint glow if switched on after the "expired timer forced off thing", if switched off they are totally off (no glow at all).

I tossed up between the Greek 'un
and Room 101 T5. In hindsight, Room 101 does the biz better.

Haha Pandora's Box! You mean the one that all the evil things came out of? Sounds about right for the J519! Or did you mean this one from 1975? Much better ;-)

From my end of the microscope
that there Pandora's Box, the one T5 TDi calls J519 suffers from Premenstrual Syndrome. Mine enjoys some mardy days. Some days J519 flattens my battery. Some days it doesn't. I send it to purdah by switching my interior lights off when I leave the van for more than a day. Switching the lights on when I want them, and off again when I don't is not a big deal. |

The J519 (behind the dash on the passenger side) has a role in the interior lights. I think there is a fuse that is also link to to the J519 so it's vital to test each fuse with a test lamp or meter. It is best to test them in place because you may cause codes to cause confusion later.
Another oddity is that the way they work. With a permanent earth, a switched earth and a live that isn't necessarily live all the time. I'd definitely start with the other fuses and see if LED bulbs have been added.
Wash my mouth out with soap  but there is an excellent description here - https://www.vwt4forum.co.uk/threads/switched-earth-in-interior-lights.1279274/ |

I think my interior lights stay on all the time when the ignition is switched on, but I haven't actually tried it for any length of time. When the ignition has been switched off for a while they won't switch on unless I close a door, then they stay on for about 10 minutes, then automatically turn off (if I open & close a door, they will come back on for another period).

How about running a supply from a piggyback fuse up to your interior light switch Steve. |

Thanks guys. I've tried with the ignition on, off, engine running etc., etc.
Even sitting in it with the engine running, there's no power at the white socket on the left side of the dash or at the light itself in the roof. It's either looking like a fault in the BCM, or a loose connection in some hidden location. I see that some people have wired connector blocks etc. beneath the rubber mats under the front seats. Do all vans have this? Do any of the interior lights wiring go through here? Cheers lads for the suggestions so far. :) Steve.

My T5 switches off the the interior lights approx 10 minutes after switching the engine off. Have you tried it with the ignition on ?

Each fuse has a couple of contacts on it's back. They are difficult to see. If you use one of these you can check your fuses. As the interior light works with the ign off: - With the ignition off. If the fuse is live at one check point but not at the other check point then it's a dud. |
