door pillar electrics

morning, I’m having -what I think is an electrical dry joint problem with the petrol release cap and the interior sensor button both intermittently not working (and also the drivers door not triggering the courtesy light).

Starters for ten ?
 
I think the fuel release works with an open door, seeing as your door doesn't trigger the interior lights, then it may be the door microswitch? Search for that one maybe? Best of luck
 
Sure there lots of threads on here about door switch? Do you know hownto search Google and 'a2oc' on the end?
 
I'll have a go. I think the swith is connected to the door lock mechanism - rather than old style push putton on the a-frame. Might try spraying some switch cleaner around the lock. :)
 
Do you have VCDS?

I used to have 'a cheap copy' and have one of those long blue USB cable things - but cheap and took ages to get working.

Are you suggesting it may have a code thingy ? I might have a look when the rain stops :)

Would you bloody credit it! Just been out to start and take a look - and alls back to working fine (now the rains here)

Must be heat/sun related - expansion issue with the microswitch. will keep an eye on it.

cheers guys
 
Classic dry joint symptom. If you have a soldering iron you just need to reflow the solder on the printed circuit board that feeds the micro switch. Getting the thing out of the door is the issue.
 
Door open microswitch rarely suffers from dry joints. More likely covered in grease / dirt, the sealing cap broken on the switch or the operating cam flaking paint.


Try a good flushing with WD40 down the area the lock pawl moves in the door.

My experience tells me otherwise. We’ve done a few of these now and never seen grease in them. The plastic finger can also wear down which can be fixed.
