notworking

Hi there, never used a forum - nor know much about cars - so please bear with us. I've had my BMW for about 18months and it's been great with not much trouble at all. About 4 weeks ago the battery died - alarm kept going off when jumped started and stayed on!! The alarm was the original system...

just took my car for an mot failed on two things one my lights have no reflectors in thanks ebay(sorted) and the other thng is my hanbrake on the drivers side isnt working my question is can they be adjusted or will it be better to just by a new one
