Fecking alarm keeps going off

[MrFwibble]

Past few days the car keeps going ' beep beep beep ' and flashing the indicator lights. Press of the keyfob shuts it up but it will just do it again.

Annoying at 3am

Scanned with vagcom, only errors were:

I've done some searching and seen some mentions to replacing the drive side door mechanism, is this easy, any vagcom coding required?

Looks to be part 1T0959701C ?

Any help, driving me & neighbours insane.

I'm far from an expert but isn't the fault pointing towards the interior sensor? Looks as though it's complaining about signal loss, would this not be what's triggering the alarm?

Does a double press of the key fob not switch off the interior sensors when you lock the car? Might be worth trying to see if this stops your alarm going off, if it does then I'd say your internal sensor is the faulty part.

 

[MrFwibble]

Yeah I thought that at first, but i searched around and most people were saying that error comes up a lot on the Leon.

I cleared all the codes, locked up and waited. Alarm went off, checked codes and nothing re-appeared.

Tried the double-press trick, didn't work either

We had this exact issue on our old car, it was the drivers door control module. Our interior light used to come on too but that doesn't always happen.

 

[MrFwibble]

Yeah I'm beginning to think that's what it is. I don't have any other symptoms such as the interior light coming on or door open warnings on the dash.

Going to a VW specialist on Wednesday, hopefully can find out for sure.

 

[306Chris]

I had this and stripped the door unit down, found loose wires into the multi plug which goes into the control unit

 

[MrFwibble]

Could be that. It all started after I jet washed the windows, wondering if some water got forced inside the door?

Hope those control units aren't too expensive !

 

[FizzyFR]

I actually took our door panel off and noticed that when holding the module I could apply hand pressure to the side of it and it would work correctly. They are obviously not the most robust things ever but take it off and have a look, you never know.

 

[MrFwibble]

Ah interesting. Was it hard to remove the door panel?

Does the module require any vagcom coding when fitting a new one?

 

[MrFwibble]

Answering the first part myself, door panel removal guide found here http://www.seatcupra.net/forums/showthread.php?t=167381&highlight=Door+card+removal

 

[FizzyFR]

Yes you'll need vcds to put a new one in, no it's not hard to remove, just common sense really.

 

[MrFwibble]

Cheers, might have a go at the weekend

Quick update to this. Took it into my local dealer, they scanned it and it showed the alarm being tripped by

"Rotary latch switch for front lid" which translated into normal person language means the bonnet sensor.

Have unplugged this and will wait and see if it fixes the problem. £33 for a diag scan and hopefully a fix.
