I know this isnt the correct place to post this but im in need or urgent help. Im off to pick my little boy up tomorrow 150 miles away, so today i replaced my cossie's battery which was knackered. this all comes after i had recently replaced the fuel pump... anyway.

the problem is when i turn the car off im getting a quiet contiuous ticking sound coming from under the steering column. What could this be??

thanks in advance
