Leaving the motor for 3 weeks?

[Chilli]

What should I do? The alarm has played up recently, so should I disconnect the battery? Will that feck anything else up?

Leave on the assumption it will be flat any way by the time you get back.
By a trickle charger and leave it pluged in
Lend to a fellow PH'r to drive and keep the battery charged.

3 weeks? mine has been sat there 3 months. if it isn't covered in an inch of grime and 'amusing' drawings i will be surprised.

if the alarm is playing up, take it to the dealer and leave it with them to sort whilst you're away.
