Chrisg Posted December 19, 2005 Report Share Posted December 19, 2005 OK this is a july 1999 quattro T Sport. Wife opens garage then boot shuts boot and a loud beeping noise starts from the inside RH rear corner in the boot. So car unlocked , drivers dorr still shut no key in ignition. Started car up-- noise carries on. Stop engine -- carries on Take out key -- carries on then just stops -- like by magic !! This is a loud noise -- like a reversing warning on a truck. Seems to be RH rear corner , close to the rear light - but behind all the carpet / trim w.h.y. To avoid me being in the doghouse .... any ideas please Link to comment Share on other sites More sharing options...

Paul Posted December 19, 2005 Report Share Posted December 19, 2005 beeps from that area usually indicate something is up with the battery back up alarm. many many posts on the TTforum about it. Search "beeps" Im not sure the solution as there were many theories. Some people have had the back up battery/alarm unit replaced. Link to comment Share on other sites More sharing options...
Chrisg Posted December 19, 2005 Author Report Share Posted December 19, 2005 Thanks Paul WE have thouight about it during the day and have come to the conclusion that it may, may, be connected to the alarm system. I'll search on the TT Forum...... not been there for a very long time Might this show up on Vagcom??? Link to comment Share on other sites More sharing options...
Paul Posted December 19, 2005 Report Share Posted December 19, 2005 it may well do. Link to comment Share on other sites More sharing options...
Highlander Posted December 19, 2005 Report Share Posted December 19, 2005 I had this a couple of times when I had my S3. The dealer checked it out & reckoned that it was something to with the immobiliser. Nothing conclusive was ever found & it didn't happened again Link to comment Share on other sites More sharing options...
Chrisg Posted December 20, 2005 Author Report Share Posted December 20, 2005 Checked out on the TT Forum site, seems that if the battery backup fails you have to replace the alarm unit at £150+ as the battery is built in ! OK yesterday evening and this morning -- think we will monitor carefully Thanks for your help ! Link to comment Share on other sites More sharing options...
Dallan Posted December 26, 2005 Report Share Posted December 26, 2005 1.8T Sport (at the time). Sounds familiar.... when I opened the boot with the KEY.... (did not press the remote segments)and on opening the boot the beeping started.... It's the alarm). I was able to start the car and the sound continued and then shut off after a very short time. When I got home I locked the car in the usual way... with the remote and all locked up. I then tried the key in the bootlock slot again, and the beeping started. I shut the boot and relocked the car with the remote. Silence. Tried opening the car with the remote, and then the boot before opening the doors.... silence! All was OK. It says in the book (somwhere!) that if you open the boot with the KEY without first disabling the alarm/immobilser with the remote, the alarm will sound. Perhaps this is what happened to you??? D.

Chrisg Posted December 27, 2005 Author Report Share Posted December 27, 2005 brilliant ! well yes she thinks so but cannot really remember but possbly hit the middle section on the key - the bit that opens the boot ?? Anyway no problem since but I'll try it out for peace of mind. Thanks again Link to comment Share on other sites More sharing options...
Ari Posted January 2, 2006 Report Share Posted January 2, 2006 You should be able to open the boot with the middle button on the key fob without the alarm sounding (at least you can on mine). But the noise you describe does indeed sound like the (rather pathetic) alarm going off. Link to comment Share on other sites More sharing options...
Dallan Posted January 3, 2006 Report Share Posted January 3, 2006 You are correct... you CAN open the boot only with the middle section of the remote control - without triggering the alarm. However, if you open the boot with the key in the slot when the car has been previously locked and immobilised with the remote control (top section of key)- then the alarm will sound.... I agree it is a pathetic sound, and likely to be ignored...! The handbook describes many ways of locking and unlocking the car with the remote (all parts) and with the key section... number of turns, clockwise, anticlockwise etc.... all a bit confusing and too clever by half!! Happy New Year! D. Link to comment Share on other sites More sharing options...
Chrisg Posted January 4, 2006 Author Report Share Posted January 4, 2006 Well this morning she gets to garage ( lock-up in cul de sack opposite our house)and as she enters garages, about 16 or so, she can hear this beep beep beep................ Yes guess what. No idea how long it had been going . Stopped as she unlocked the car..... Might be forced to get my local independent to have a look - and disconnect the siren bit !!

Milo Posted January 5, 2006 Report Share Posted January 5, 2006 It's a testament to the A4 alarm that it can be mistaken for a humble beep - my bedside alarm clock is louder then my car's alarm Has anone retrofitted a different siren to the OEM alarm?

peterb Posted January 5, 2006 Report Share Posted January 5, 2006 Chris, I've never experienced this problem, but I do understand that it is indicative of a low state of charge on the backup battery within the alarm. It would appear that there is a strong correlation between this and a poor state of charge of the main car battery - an ageing battery, short journeys, cold/dark mornings and evenings all contribute. Try taking the car on a long daylight run, or putting it on a mains charger for a while ... or replace the main battery! I'm guessing that the alarm system is designed not to draw on the main car battery when the voltage gets below a certain threshold. Link to comment Share on other sites More sharing options...
Chrisg Posted January 5, 2006 Author Report Share Posted January 5, 2006 Thanks Peter Would Vagcom show up anything? I can easily pop over !!! Original battery, why it's only 6 1/2 years old ! Except for my old 80 Sport this is one of the oldest cars we have owned for 20 years, and the 80 is only on battery number three ! I gathered from the TTForum ( thanks PaulS3 )that it appears to be a backup battery issue. The battery is not replaceable - only the whole alarm unit. Perhaps I can just disconnect the alarm unit as it is fairly useless anyway! If I fit a new main battery is there any problem with unsetting any settings ( yes I have the radio code !)

peterb Posted January 5, 2006 Report Share Posted January 5, 2006 The alarm has no fault logging capability, but other modules (eg Nav unit) in the car may record instances of the voltage falling below a certain threshold. My guess is that the main battery won't be lasting much longer, so why not replace it now and save the hassle when the car won't start (you know who'll get the blame the day it fails!)? You could disconnect the alarm - the bleeping can only last as long as the backup battery can sustain it! Settings lost when the battery is changed: radio code and current DIS values, window one press up/down. Can't think of anything else. Link to comment Share on other sites More sharing options...

[/ QUOTE ] Oops! Of course it does - the alarm facilities are split between the other controllers: Central Locking, and Interior Monitor, Central Convenience etc. ... depending on car model. However, I've never seen anything listed for the backup battery. So, yes Chris - if you want to come over Lower Earley direction, I can check the fault codes for you!

Chrisg Posted January 6, 2006 Author Report Share Posted January 6, 2006 Thanks Peter, I'll PM you. It may help to eliminate a couple of items. Last night she told me that as she earned good money didn't I think a new battery was a good idea anyway , just in case it let her down at work one dark snowy january evening Yes dear Link to comment Share on other sites More sharing options...

[/ QUOTE ] About a year ago someone broke into my A4 while it was on my drive - the feeble beeping from the alarm was so quiet (we were in the lounge less than 10 feet from the car, but the other side of a double glazed window) that we thought it was the microwave in the kitchen. I've not been able to find anyone who can fit a louder siren - the Audi one has 3 connections (looks like ground, power and enable), but if anyone turns up anything then count me in!

Chrisg Posted January 13, 2006 Author Report Share Posted January 13, 2006 The latest situation Peterb did a VAGCOM for me The codes were: Address 35: Centr. Locks Part No: 8D0 862 257 E Component: CV-Pump, Alarm, RC D13 Coding: 13130 Shop #: WSC 06325 3 Faults Found: 01134 - Alarm Horn (H12) 76-10 - Terminal 30 missing - Intermittent 01134 - Alarm Horn (H12) 77-00 - Internal Supply Voltage 01134 - Alarm Horn (H12) 49-00 - No Communications Main battery was also a bit on the low side. Looks like a weak battery , original 6 1/2 years old so I've been made to buy a new one ! Too embarrassing she said..... spend the £45... Will fit over the weekend and see what happens.

Dallan Posted January 13, 2006 Report Share Posted January 13, 2006 Interesting reading......been following you story with the alarm (whisper!?) and its tantrums. What effect did the installation of new battery have on codes such as radio, DIS, etc. Regards. D. (Audi S3) Link to comment Share on other sites More sharing options...
Nelson_R32 Posted January 14, 2006 Report Share Posted January 14, 2006 You'll be needing 1 of 8L0951605A (about £35.00) The siren contains a back up battery for the alarm. It'll start beeping when its getting low. Link to comment Share on other sites More sharing options...
