  2. Seized front brake caliper - or is it?

    Been a while since I've needed a good post. Just tried to drive my Smart to Inverness (469 miles) as you do, driver's side front caliper stuck on about 70 miles in to the journey. Started with a high pitched intermittent squeal (I initially thought it was the heater fan - but it wasn't. I wish it...

  5. 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...

  6. Identifying a noise

    For a few weeks my 09 Smart Passion has developed a slight noise. When I start the engine & drive off, I get this VERY slight & quiet "tap, tap" noise but it lasts for no longer than 5 seconds & it doesn't happen again whilst driving even if I stop with the stop-start function running. It is...

  7. Found this in boot

    Whilst clearing out/vacuuming my boot recently I found this item. Just wondering if it is from my 2009 Smart Passion ForTwo or just something that has randomly found it's way in there.

  8. 451 Side Skirts

    I noticed the side skirts on the left side of the vehicle appear to be a bit loose... http://i64.tinypic.com/2r7vez4.jpg 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?

  9. Lacquer Missing - Cure?

    An over-enthusiastic valet pressure washer has stripped off small (3-inch) patches of lacquer under each of the windows.

  12. 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
