well been fine all weekend, then none stop today 🤨

cheers just cleaned all connectors and alarm seemed to arm ok first time, is it really likely to be something that simple and not the boards gone faulty?

the scanner came up with shows the below

Ok ebay said the other part number i think thats for the plastic cover its 1z0951171 its the ultrasonic alarm sensor one of these https://www.ebay.co.uk/itm/293811201582?hash=item446883262e:g:NGoAAOSwB4Zfn~hK&amdata=enc%3AAQAHAAAAoKrT%2BAek%2FnIlF%2BPGAlAUQDosTq5r%2Fpc9bTP9bq8p3wFj72aZrwLecv8P5Ui8wqnh4PqoWVoxsq1nA4rhH3%2BitRCCx09ptZElHA91HdJGvXcrzkEYJQ%2FxC%2BnlODuxJrbbJlWdBh%2FJdiDCqagP4FVbHdFL6BzbGeV2PMomDW%2Fas1b5VtNe6W6Vr9Iejco9wkXl%2FYxwrFkHKDDv5tqH8%2BZhyu4%3D|tkp%3ABk9SR8j9ycCjYQ

Hi MicMac, what other info would you need?

So im getting the error 03156 which the internet doesnt bring much up for, found one that states is this sensor which i believe is part number 1Z0877829B Does this need to be coded to car as odd add on ebay says might need coding, or is it a straight swap?

Cheers, Year its a 2009, facelift model like the above

it also wont read steering angle module

Right so im using https://play.google.com/store/apps/details?id=com.bluetooth.vagerasedtcall and everything seems to be fine, but this one unit Is this the one in the drivers door? or in footwell and does it need coding to be fitted?

got replacement, thats fixed the error on the alarm horn, onto next now 😞

this sounds like its falling off, can here it rolling about inside 😁

scappers is off to swap it, if they said they didnt want it back, Id happily open it up myself lol If battery on one I took off the car was leaking it was going to replace it, but voltage is still holding over 6v and looks fine So only thing i could guess which maybe causing fault is the 3 capacitors, which i could swap, but thats just guessing 😞

guessing I got a fault unit from scrappers, fitted it, when alarm triggered flashing lights but no siren 😞 I dont believe the unit needs coding or anything else? strange thig was the unit had a rattle, like a SMD component was loose in side

I`ve sourced a local 2nd hand unit for £10 so for sake of that much if it lasts a year or more bonus. I dont know if the variation is where the units where made. mine just says 1K8 951 605 but no letter at end. When people refit them what do you use where the rivet used to hold it to wing

Cheers, the part i took off car didnt have a letter on end, so must have presumed it was a C

well there must be another number, as quoted reg and theyve said its £200 included VAT does anyone know if 1K0951605 is compatible

there not £155 now 😐 just been quoted £355+VAT, so £426 for the below 1k8 951 605C

See i'd go for faulty wiring to LED, but its the fact one time it worked again when alarm was armed, but the car hadnt moved, id not opened the door. But i did read somewhere the LED changed how it lights up or doesnt if theres a fault on system. then theres the error code suggesting its that horn unit which the batteries are only meant to last 5 years, cars from 2009, I was suprised they`d not leaked tbh

did you ever measure the battery voltage before replacing, mines showing 6.98v, but error code is Alarm Horn -h12 01134

So after taking the unit appart theres no signs of leakage Measured the voltage and this showed 6.98v So is it lekely to be the bat or not?

Cheers My thoughts are take unit off, and put arch liner and wheel back on, and not have a alarm for a week or so Then open the unit up, see which battery is in it (as there appears to be 2 sorts) and state of PCB then if its worth repairing to go down this route, and fit back, if its not then order one from Alliexpress etc, and fit this when it arrives

Yeah, i think its other module that controls locks in the door. but never tried, just if i have to wait for part cant bothered resealing unit and fitting it back in lol

Does any one know what happens if you leave the siren alarm module unplugged, obviouls no alarm noise, but would the central locking still work?

1 = yes (just no flashing LED on drivers door) 2 = so lock car double press to disable the dead locks, windows already down when armed reach in pull handle 3 = correct stopped working again, disconnecting the module in door, then reconnect. LED works as it should when armded e.g. fast flash then steady flash. but after a few hours no LED again

When i say the alarm goes off, I mean its triggered in way you expect, e.g turn alarm on all doors locks, when a door is open or windows down and wave inside then the alarm goes off. Not getting any false random alarms. The doors dont lock if one is open etc. The cables are fine as i had all these out few weeks ago as the airbag sensor wires broke. but the LED stopped working well before this.
