Intermittent Alarm 2002 Passat Estate!

**EddyStone** · 07-05-2006,12:00 PM

Hi.
I have an intermittent alarm problem on a 2002 TDi Sport Estate.
Carpets OK. No Water in passenger footwell. Drainage holes in bulkead not blocked.
Problem seems to occure after heavy rain. I believe there have been problems with a sensor/microswitch in the tailgate on Passat Estates!
Has anyone had similar problems or any suggestions.

Thanks Ted

Hi, I bought my '01 130 TDI Sport Estate 4 months ago, when driving in heavy rain....... "glong"..... outside air temp drops to below freezing even though its at least +4c. Worst it ever been is -22c..... takes days to dry out & whilst its doing this the alarm is going off day & night. Are the outside air temp sensor & impact sensor somewhere where the water is not supposed to get?.There is an earlier thread regarding burnt out external air temp sensors, does anyone know where to look?
Local VW *********** asked about the tail gate washers, its not unkown for the water pipe to the tailgate flush & brush to fail flooding the boot locked sensor with screen wash, mine has a pretty good jet so have discounted this. I too have no probs with wet carpets, dry CCD & clean pollen trap drains.

You could try the bonnet switch, as a collegue of mine had this problem on his 51 plate passat.

Can someone tell me where the bonnet switch is please and maybe the
VW Part Number?
Thanks Ed

Ed,
The bonnet switch is mounted in the bonnet lock mechanism as shown in the diagram
