Iv got a Audi A3 sport when i lock my doors my alarm sound straight away and when iv got my doors open its says my boot is open and sumtimes when driveing my rear window wipper will constint wipe and willnt stop have you have any ideas what this could be.

Have you tried?

This should be a dealer issue. I know they are not cheap but you are going to have to take the inside door panel off and then you need to take out the window to get to the lock mechanism. Door panels take special tools.

factory fitted alarm/immobiliser,resetable with doorlock/key.not all fitted with interior sensors(different markets)to test lock (with drivers door window open)leave car for about a min then try opening door using inside door handle (pull lever).horn will sound intermitantly....to reset shut door and press lock button on remote.

try changing the drivers door lock

Enter car from left rear behind the driver and see if you can manually unlock it from the inside. Then use remote to test it.

I've been dealing with similar problems (windows and sunroof dead, power locks iffy, dome light doesn't work, random chiming) and best I can figure is:

a) get rid of the leak and any standing water
b) depending on the year of your car check the relays and/or central locking module

I spent a lot of time checking the ECU and door interior parts and those were both dead ends. I also thought the standing water on the floor might be shorting actual wiring, but now I've eliminated that as well. Although my alarm hasn't been going off, the "door chime" has and the instrument cluster sometimes shows 3 or 4 doors open while driving. VAG-COM showed some alarm trip type faults as well. Central locking is my next move when I've got some time.

you need to get it code read,there you can see the last four alarm source and take it from the code,my guess will be interior monitoring,i think you have a switch on the drivers door pillar behind the seat belt,press it when you get out to see if it stops the alarm going off...the tone can be ajusted with vcds software

drivers door lock needs replacing,if you have the central electronics checked it will give you a code,and i will possibley be that door,the microswitches play up in them quite a common fault

if unable to turn key in boot then you will have to drop the seats down inside and climb in. remove the rear door panel and move the release mechanism manually. Make sure the vac pipes are connected and the mechanism isnt siezed.

TL

this sounds like a faulty 'boot' switch. Many of the older models had issues with picky switches
