Hello

Trying to suss out why the alarm LED in my Roomster TSI drivers door isn't flashing when car is locked. Topic doesn't seem to have come up elsewhere.

Tested the alarm by opening door with key and it works fine - WITH LED FLASHING while it sounds - so it's probably not bad wiring in the door.

Main suspect is a knackered lock microswitch which has failed in the 'door closed' position (fortunately) and I'm about to replace it, but this packed up about a month ago and the LED was still flashing until last week.

OR .. could it be the alarm NiMh battery? Car is 2011 so possibly - but LED should run off main battery right?

Any suggestions gratefully received.

Cheers,

Ian

 

 

 

Hi S, can only relate what my problem was.

I had 2008 model which after a few years the red alarm light would work intermittently, eventually stopped working altogether. Wasn't that bothered about the light as everything was working OK.

Eventually other things stopped working, including the drivers window, very awkward getting out of car parks. 

Took the door card off but found in the rubber cover between door and car multiple breaks in the wiring, replaced loom, everything working OK.
