is it possible to just permanently disable the alarm. Do you know is it located in the same area as that photo I sent earlier? And is it complex to remove it

 

That's just the sounder - the alarm is integrated into the car  electrical gubbins, hence the need to read codes.

Do you know where the sensor is in the bonnet?

 

Should be some wires attached to the bonnet catch - microswitch should be in that area.

Thanks very much for all the help bigjohn. I'll try some of these bits tomorrow and see how we go.

Sorry I can't help further as I can't even go and have a look see as sadly I no longer have a Skoda.

PS You haven't disconnected the alarm thus far, just the alarm sounder.

 

He has disconnected the alarm control module which is located under the RHS front wheelarch, this I believe includes the sounder but it could be there is a seperate one.

 

However the hazard warning lights operating when driving does question the above.

 

I think there might be a seperate problem with the body control module as the alarm system should not be operative when driving and certainly not when it has been disconnected, this problem may have caused the BCM to wake up during its slumber which could/would/may have caused enough volt drop to trigger the alarm.

 

If you resolve the additional problem you may find that the alarm control module works fine again.

 

Are there any other electrical gremlins?

Is it different on the Octavia mkII compared to other VAG cars? I helped sort an Audi A4 Avant out with a similar issue and in this case the "siren" module was at the rear and a total swine to get to, Had to take lots of the rear of the car to bits. I managed to split the unit apart and replace the battery but it did break some of the plastic in the process.

 

The part number I have noted from that time is "1K0951605"

I'm not sure, I'm relying on my not so good memory, the Octavia 2 and the facelift Yeti have the same unit under the RHF wing but they are the same platform, touch wood the one on the Yeti is still functioning, no PCB  battery leakage yet.

If it's the same unit and you can use a soldering iron / wick then battery is changeable but the case is clearly not designed to come apart easily, presumably for security reasons!

The battery used to be a non commercialised size, with a bit of bodging a smaller capacity one could be fitted, the case somes apart with patience, ultrasonic welded no different to any other throw away article that needs to be water tight, throw away meaning designed for production not designed to be dismantled for repairing.
