HELP! Can anyone fix this please?!

Removed alarm siren, opened up, bought all the bits as per the guide, but my board is shot! The battery has leaked for some time, probably years.



Resistor and fuse? has burnt out on the top right corner of the pic and the battery terminals have led the battery acid onto the board and attacked a few components. Fair to say this alarm won't work anymore. People on eBay want a small fortune for an alarm that MAY be in the same condition as mine so not sure if I want to go that route?

Will have to buy some of these and use them as my alarm for the time being!


lol.

That board is shot, you have no idea what the acid has done to the tracks or the other components on the board in the affected area. Ebay, beakers or new alarm is the only option.

Such a poor design!! Will have a look at the scrappers tomorrow before eBay.

Cheers.

Are B5 sirens compatiable on the B6's???

 

[adamss24]

Nope, b5 had a horn setup, later facelift models had an alarm siren but i have no idea if they are the same... I am breaking a few cars including a few b5, c5 a6 and audi a4 b6... Let me look for one tomorrow, might have one somewhere...

Ok cheers Chris, Saves me a trip to the scrap yard as they only have B5's in.

What's the part number of the old siren ? Any picture of the connector side ?

 

[S4_dan]

Part number is 8L0 951 605

It's a 3 pin connector as in this guide here, photo 10:
