S3 Alarm prob

[ghill]

OK...after a few months of tracing a hesitation in engine I've finally got S3 running great. YES!!!!

All pipes now Forge silicon, new coils, new plugs, new N149, new N75, new mass meter, 007 Div valve, re-insulated coil pack wiring...lovely super- smooth power and feels like 270bhp again

A week of perfect driving and now my alarm's going off all the time! Pretty random, often after a day or three of being quiet!

The last few days there's been a weird clicking noise coming from the BOSE subwoofer, or somewhere round there...quite loud, can hear it from outside the car easily.

Recently got new VCDS cable from NHN (which is a joy to use and just works 100% every time unlike the cheapo ebay ones I've had before which wasted lots of my time before being burned) and only fault codes are...

Cardiff Audi have quoted approx £500 for these two parts!

I've seen reports of leaking alarm horn batteries and will swap the parts if I know where they are.

Tonite I dismantled half of the boot while alarm was screaming but then it got dark and alarm stopped!!! LOL ... My car has a great sense of humour and is now unlocked on driveway!!!!


Firstly, can anyone let me know where the above parts are located and secondly do you think this is what's making alarm cry out in middle of the night...or maybe a battery prob not showing up on VCDS????

Tonight the alarm was screaming and wouldn't even shut off when I clicked the key fob!!!!...until I opened the boot/door

I don't think she likes the 4 new Falken 452's I put on today!

I can live without an alarm!!! Is there an easy way to disconnect it?

The alarms in the boot inside the near side hatch, IIRC you can access it by removing the rear light rather than stripping down the panel, if you do a search something will come up as its quite a common fault and I seem to recall a few posts recently about it.

e2a: I'm pretty sure you can get the batterys from maplins quite cheaply.

ok cheers - looked like getting the light off was the best way to get in there and I'll get back onto it tmrw.

all quiet now! removed the alarm horn which was buzzing to itself so pretty sure this was the cause of the problem.

Rear light off the only way to get at it as far as I can see

please can my car now behave for a few months!!!

You need new batterys in the alarm module, pm westle i think he is or has done his, you can get the batterys from maplins
