Thankyou drewbee

my hazards were flashing before i tried to open the car and surely 2 fobs batteries would'nt go at the same time.

thanks

Anyone have an idiots guide to resynching handy? I have the same thing, I have changed the batteries in the fob, but didn't get a handbook with the car so have no idea how to resynch.

Hi tux Re-synchronising the remote control

The audi book says - if the door is locked, use the key to unlock the driver's door
-Press the unlock button on the remote control
-Insert the key into the ignition and switch on the ignition
-Switch off the ignition and remove the key
-Press the unlock or lock button

hope this helps tux

Hey brownie, i had'nt noticed the hazard light until you mentioned it so i'm wondering if the all do it, lets hope others try it and let us know.

Thanks

Check the drivers door loom.
You get breaks in the wires in the door shuts.

Can you tell me how i can check the loom for breaks as i'm not that technical or would i have to get an auto electrician to look at it.

Thankyou PW Motorsport

Take the door card off, and have a check.

Check the wires that run in the door shut rubber boot as well.

You often get other faults ie: the mirrors, airbag light, or the windows not working......

my car will lock all doors with the key so if there was a break in a wire would that not be the case ?

Thats the same as mine, now someone has said it may be the convenience control module (windows alarm central locking etc)
Anyone think the same or not.

[brownie 25]

did you do anything with the siren in the boot check to see if batteries have leaked or anything

Not always.

Hey brownie,

I took the siren out as the battery acid melted everything beyond the point of repair (i tried the rechargable repair to no avail) but this was a few months ago and surely this problem would have happened straight away. I have now got a fault code: alarm by sensor alarm closed 01463 some one has said it maybe the convenience control module

thanks
