There was more than one engine available for that car. You will need a copy of the original registration document. You could also look for the engine code on the engine block. But the paperwork (V5 in the UK, Pink slip in the USA), is the easiest way to do it.

when a battery is completely drained, it shortens the life or could kill it all together. Time for a new one. Doesn't need to be coded.

Sounds like it probably is a relay that's died. You will need to look in the relay box, assuming that car has one, and with luck, under the lid it will tell you which relay does what. Replace the turn signal relay(s). If they're not in a separate box, it/they are probably somewhere behind/under the dash. Sorry I can't be more specific :{
