    when i first start my car in the morning i get a 'pinging' sound. It repeats itself about 4 times then stops. i dont think i get any warnings on the dash or anything and it dosent do it throughout the rest of the day, only on first start up.

    sorry for what maight seem daft questions but i dont have a handbook with my car and dont know what half the things do:think:

    4 beeps from the rear of the car is normally an indication that the backup battery in the alarm module is struggling, and/or the car battery could be on its way out

    well its defo 4 beeps and only when i start it first thing in the morning.

    so is there a battery i need to change on the alarm module? is it your normal run of the mill battery?

    car allways starts fine by the way.

    :ermm: dont think my car does this. I have not noticed anything on the dash when i start the car and have not put my seat belt on.

    should there be some kind of warning or showing on the display?

    once again sorry for all the lame questions but i am still trying to source a handbook to let me know whats what.

    Car battery on it's way out, try using jump leads to start the car, even though the battery is not dead that surge in power is enough to trigger that alarm, try the jump leads and see if it goes away, if it does you need to replace your battery as it will soon fail, if it doesn't, then you will have to look into somthing else.

    I'd start with the main battery as ronny suggests - the current draw from starting the car can be enough to drop the voltage on the alarm so it thinks someone is tampering with the battery. If you still get the beeps with a jump start then it could be the alarm module battery, but this is a more involved job, either replacing the alarm module itself (£80) or taking it apart and replacing the rechargeable batteries inside - not standard, but some people have done it.

    £70 for a new Bosch Silver top - not really the end of the world, cheaper and more useful than buying a new alarm module.

    WOAH GUYS!!!

    It's just the back-up batteries in the alarm...

    If you're willing to dismantle the alarm, it's around £12 for 2 cell batteries from Maplin.

    Info here!
    More specific info here!
    Did mine last month, no more 'quad-beep' on start, definately nothing wrong with my car battery!

    you have an avant or saloon? in my B6 its behind a trim panel on the o/s behind the wheel arch.

    If you ping the siren open you will see the cells, just replace them as stated earlier, make sure you're handy with a soldering iron.

    I didn't suggest go and buy a new battery, just what the cost would be. The suggestion was try it with jump leads to another car with the engine running and eliminate the main battery as this is easy to do and will then point the finger firmly at the backup batteries.

    No the car might explode!:haha:
    Nah seriously them batterys are hard to come by as the company went bust a few years back.
    I got a new siren on ebay germany for €30 or so a while back.
    Or do as Hiltoa said in the links he posted above (i think he said halfords has an alternative)

    Maplins stock appropriate cells that fit (with simple tweaks as per first link in my post above).
    Stock number BN24B = £5.99 each, you will need 2.

    @ macattax - that ebay link appears to be for the horn, not the alarm.

    i have tried to search under button cells etc but i dont think they do ones that ar thick enough. most they seem to go to is about 5mm and i think the ones we need are 11.5mm

    course i could be missing them.

    Maplin - BN24B

    None of the cells shown on CPC appear to be the right size (search on Batteries, NiMH, Button cell type, then filter by 3.6v)

    isn't there enough room inside to fit something like the recharchable batteries from a cordless phone?. the type that come with a pair of leads attached. all you'd need to do was attach the wires to the metal terminals where the + and - terminals on the battery touched.

    in fact, better idea, solder 2 wires, run them outside the alarm case and buy a seperate battery holder. that way the next time they go it's just a matter of changing the batteries, don't even need to open the case up
    i'd be tempted to try one of these

    http://rswww.com/cgi-bin/bv/rswww/searchBrowseAction.do?Nr=AND%28avl%3auk%2csearchDiscon_uk%3aN%29&Ntk=I18NAll&Nty=1&Ntt=battery&Ntx=mode%20matchpartial&N=4294729709&name=SiteStandard&forwardingPage=line&R=4725517&callingPage=/jsp/search/search.jsp&BV_SessionID=@@@@0687621473.1182680169@@@@&BV_EngineID=ccckaddlfikedgfcefeceeldgkidhgj.0&cacheID=ukie

    and one of these

    could be worth a go.

    does the battery meat all the requirements?

    amp needs to be 160-170 i think dosent it and the the originals were 2 x 3volts and this is 9 volts

    does any of this make a difference?

    hmmmmmmmmmmmm the link doesn't work

    anyway, it's on the RS components webshite

    part number 472-5517
    8.4v 150mAh
    the standard batteries would be 7.4v and 160mAh so it'll be close enough plus it makes it a doddle to change the battery the next time it goes

    well credit goes to shineydave for this one but this is what i came up with.

    seems to do the job, time will tell how long the battery will last.

    it needs to be a NiMH really as a conventional battery isn't designed to be recharged but all credit to you, that looks a neat job. does it work ok then?

    i have only put it in this afternoon so we will need to see.

    so i really need to put a rechargable one in there then?

    will this do any harm in there for a couple of days untill i sort one out?

    its not going to bugger anything else up is it?

    It will only bugger stuff up if it:
    A. pops due to excess hydrogen build up within the cell, spraying its alkali guts around.
    B. fries any circuitry in the alarm that's not rated to 9v (remember the original batteries were 7.2V combined).

    Still, if you don't try, you'll never know...

    better get a different one today to be sure then. I take it that the one i buy off the shelf will not have much charge in it. When fitted the system will charge it up then right??

    i'm not sure, never bought recharchables before. i've just ordered a NiMH one and battery holder from RS to have a go at Tonyas, i'll report back before the end of the week.

    well i went and got a ni-mh today to fit, it was only £3 so no dramas there. The other one that i fitted seems to be fine at the moment though, started fine this morning with no ping ping ping ping so thats good news and i have not heard anything go bang yet so even better.

    will still fit the ni-mh just to be sure though.

    but does the alarm sound if you drop a window, arm the alarm and wave an arm about in the cabin? you have to wait untill the red led in the lock button starts flashing steady, about 30 seconds or so after you arm the alarm
