if the garage done any work atall to the car & it came back to you with the noise after they messed with it i would make sure they fix it pronto and would not wait a week or 2 and hope it goes away. man up & get the muppets at the garage to sort it if they caused it 

thats what i said hubby1959

sounds like you need to take out the bulb holder & disconnect the wire plug as they sometimes gum up and also check the bulb contacts as they degrade with age and damp.

i usually apply wd40 on all of the connections and make sure the contacts are clean. then refit bulbs etc and try the lights.

brake shoes/pads wear depending on the type of driving. town or city driving will wear them down quick.

i get about 28 months out of mine on the fronts then about 36 months rear there abouts.its down to all the stop starts

for lights etc so 2 yrs on the pads is about usual i recon.try your local halford service center as they do them for life.

so you pay once & they wear out they do them for nothing next time.

have you serviced it & changed the fuel filter as i done my sons fuel filter a while back & it's made hell of a diffrence
from memory there is no electrics that would effect the engine or no electrics atall by the filler cap or that area.
seems more a coincidence.
