  1. Continental Eco Contact 5 Tyres

    Looking to buy some Continental Eco Contact 5 Tyres sometime in the future, they don't seem to make then in sizes 155/60/15 front and 175/55/15 rear which are what I currently have fitted to my Smart i.e. the Continental Eco Contact 3. What would be the next best size tyres I could fit?

  3. Stutter (misfire) on a cdi

    Hi, have an annoying fault that has just started on our 2009 451 Passion CDI. Under quick acceleration the engine seems to stutter (I can only describe it as very similar to a “misfire” on a petrol car). It will run fine around the town fine but get it up to 60mph and it does the stutter (misfire)...

  7. Seized front brake caliper - or is it?

  10. 451 aftermarket exhaust

    Hi, I need to replace the exhaust on my 07 1.0 84hp Euro 4 in the near future. I've seen that quite a few online retailers list a BM91590H as a replacement for less than half the price of a genuine Smart exhaust. It does look quite different, more like a "normal" exhaust. By "normal" I mean...

  13. 451 Side Skirts

    I noticed the side skirts on the left side of the vehicle appear to be a bit loose... Is this likely to have happened in an accident or where someone has removed them in the past and not put them back on snugly?

  17. V11 Brabus Alloys - Corrosion Enquiry

    Hi These V11 Brabus alloys come with 2 year guarantee but really doubt they would last this long and not show corrosion. Has anyone got the V11 silver alloys - any reports on corrosion versus how long you had the wheels. Thanks Simon
