  9. Just bought my first Smart.....lights problem

    Brought my new Smart home in the daylight. I'm totally new to these cars. When I went through all the lights on the stalk, when I got home, they don't seem to work very well. The DRLs are on fine, the side lights are hardly worth putting on (but I guess that's just the poor design) and headlights...

  12. Grinding Noise When I come to a stop

    I recently bought a used '09 Passion Coupe. I noticed shortly after that when I come to stop, the brakes make a grinding noise that's rather loud. It doesn't make this noise when I'm on the highway or driving and just need to slow down. It only does it when I'm coming to a stop. The faster I...

A quick look before I set off shows it seems to have separated at the section covered by a flexi material, is this a...

  15. 225/35-17 tyre

    Hi, My Smart Brabus 451 comes with 225 35 17 tyres at the rear and I need to replace x1. So I thought I will change both together. What sizes can i get instead which will be as close as possible? As 225 35 17 seems a bit impossible to get hold of in Malta. Thanks, James
