interior light

[series111]

hi

I have just purchased an 2003 19 tdi and am have problems with the interior light sending me morse code signals.
when I am driving with the doors and boot shut properly the interior light keeps flashing on and off when the centre rocker switch is set in the middle position.
I how someone has some ideas

I would check the light switch itself first, before I go looking for a fault with one of the door switches..

Sounds like it could be the contacts touching for the light always on.

Mine does exactly the same

Anyone have any info ?

mine is doing this and im getting a click from a relay aswell which is behind the dash on the drivers side, also when i set the alarm it keeps sounding after 30 secs or so.
Anybody know where the comfort control module is on this particular model its a 2002 a3 8L

yes forgot to mention that mine seemed to clear when i opened and closed the passenger door, however looking at it today the light started to flash and then i tried the drivers door and boot and the flashing fault came and went several times and i didnt open the passenger door at all.
I would of thought that if the passenger door switch was faulty (stuck on) the light would be permanently on not flashing.
When the light is flashing and i open either door the light stays on (not flashing), close the door and it flashes again, so it seems to me the switch is changing state from open to closed and therefore working?
Ive found the light relay under the dash which is clicking on and off and it has electronics in it (not a basic relay as normal) so im probably going to try a new one of these and see what happens, hope its not to expensive!

Read that link above and they seem to be saying that the light and dash display is just stuck on and not flashing like ours.

I was wondering if the 2 could have been linked in some way just ..........

Hi

Just had a good look at mine again and what is happening is that as above the interior lights flash on and off while driving I can here a cliicking behind the dash (relay) as the lights flash,if i try and arm the locks the doors lock but the interior lights carry on flashing and when the system has armed ( After 30 seconds)The alarm goes off.

In the bottom off the doors I Have a white light and in the side off the doors i have a red light ( marker lights when doors are open)
I have noticed that the lights on the passenger front door DO NOT allways go off even though the dash says that the door is shut ( picture of car goes out as it shoud)

When these lights are on this is when i have the problem,when these lights go out it all works fine.
So would this be a problem with the door lock (mirco Switch ) or the relay
behind the dash or some thing else.
I hope between us we can sort this problem out.

i havent noticed if the light in the bottom of the door had stayed on when my centre overhead lights are flashing but i have ordered the relay today as it was only £21.60inc vat and it should arrive wednesday, hopefully it will fix it but if not at least then we can rule that out. If it doesnt fix it i will have to find which wires go to the door switch and see if its operating properly or sticking.
Another thing i noticed was on sunday i locked the car and after the usual 30 secs the alarm went off so i left it going off every minute or so and after about 10 mins it stopped and the light had also stopped flashing, nothing had been touched, no doors opened, so maybe the alarm will ignore a trigger after so many times. It seems like the alarm, c/locking control, c/locking pump and possibly some control of the interior lights are all in one unit which is located in the boot left side near the sub, fingers crossed its not that because that sounds expensive.
The relay ive ordered is called the entry light control relay part number 4d0 907 131 i will let you know what happens when it arrives.
