  1. Reserve Fuel

    Does anyone know how much reserve fuel a 451 holds and does it only go onto the reserve when there is less than one fuel bar remaining?

  2. Brake light switch re-setting advice please

    It's been a while since anything has needed doing to my 451 but now I have the well documented possible brake light switch failure. Having trouble selecting 'N' 'R' and '1' etc., brake lights not coming on very consistently and ABS warning light and ! triangle staying on. So I'm being optimistic...

  4. Brabus tyres?

    Does anyone have any other preference to the standard Yokohama tyres on the rear of a 451 brabus. The size of 225/35/17 seems rather unpopular and therefore not much choice. Thanks in advance

  5. Anyone know where this goes (451 ForTwo)?

    4181 I've just had the lower windscreen moulding off to get at the wiper arm nuts to reposition one of the wipers. All went fine and it's back together again and working. But... I then found this little bush under the front of the car and assume its something that fell off when I was...

    At my last service I had the following done... http://i66.tinypic.com/25hctoh.jpg I'm now on 17,700 or so mileage, what should I have done at the next service which will be in Jan/Feb 2018. Spark Plugs? Air Filter? I should probably have the brake fluid changed as it will be 2 years since...

    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.

  20. 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...
