Battery removal in a 146ti

[SCOOTERMAN]

A simple task I know, but what with the Italian voodoo god of electricity and the Dark Lord of Alfa electronics looking over my shoulder, I fear it could well end in tears. And an immobile car...
I need to whip the battery and battery tray out to get to the clutch slave cylinder, but *something* tells me that you can't just remove the battery in 146s without upsetting the immobiliser; talk (in other forums) of "master codes" (which I don't have) and master keys (which I do have) and "It won't blóódy start!" springs to mind...
Any ideas?

I thought the same when I had to take mine out (145) so I connected a couple of long wires to the battery terminals and battery cable connectors before undoing the main connectors to the battery. Then remove the battery with the extra wires in place so the connection isn't broken and there is power to whatever systems need it.

I don't know if I needed to go that far but it worked OK for me.

Cheers

i guess you have sorted this now, but you have to be careful of the black box of bollox (fuse box) in front of the battery. the connections can be dodgy and cause the injector light to come on and then not allow you to start the engine. this happened to me so my local friendly garage rewired it. fingers crossed it shouldn't be a problem now.

I've not got 'round to it yet; I'm a student, therefore I'm an idle scrote.
I'm well aware of the BBoB and it's dark, mysterious contents; they left me stranded in the middle of Wales (and therefore the middle of nowhere) a while back when they decided to play silly búggers.

I'm not completely sure, but from what I can piece together, if you do it fairly quickly (disconnected for only a few minutes), it'll be ok.
The master code you mention will be the alarm access code which if my 155 is anything to go by will not be logged with the National Security Register. As you have the master key, the immobiliser can be easily reset, but if the alarm stops recognising the radiokeys, then yoiu loose alarm and remote central locking. To be fair though, that should only happen if the battery goes completely flat, and you try to start it, or if as happened to me, some muppet fails to tighten the battery terminals correctly

BTW, the security code held by the security register are.
1 Key code- the physical cut of the key.
2 Alarm code- used to access the reprogramming function of the alarm.
3 Immobiliser code- used only in emergency starting prodeedure when a fault occurs and the immobiliser won't recognise the transponder key.
