hey all, firstly, Hi to everyone, Im Alan, just got hold of a T reg ST24 in silver and secondly, Can anyone tell me a couple of things please

1. The alarm sets ok, but when it goes off, only the indicators flash! any ideas as to why??

2. Have put new sidelight bulbs in the front as the old on passenger side was flickering, now even the new bulb does it. ???

3. If i give it an oil/filter change, whats the best/recommended oil to put in?
Mileage is on 149k if that makes any difference?

thanks in advance
