  2. 2010 451 84hp turbo gearbox oil change

    Morning folks. I managed to change the gearbox oil on a 451 84hp turbo a while ago, as task made much more difficult due to some sort of plastic (intercooler?) air scoop that sits right in the way of the fill plug. I couldn't see this piece on the guide I used, nor how to remove it. In one...

  4. Hissing sound after driving

    Hi all, I went to test drive a smart for two 451 MHD 2010. After test driving, I noticed a hissing sound and water dripping from the bottom of the car. The hissing sounded like air being released from a tyre. My suspicion is that it is related to the air conditioning and is completely normal. But,...

  9. 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)...

  13. 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...

  16. 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...

  19. 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?
