Finding The Engine Number – Roadster
Where Is The Engine Number? This is one of those strange questions that I get asked on a fairly regular basis. I didn't understand why it was necessary at first until I was told the reason. Apparently, in some countries, if you import a car, they want to know...
Fixing A Windscreen Chip
The worst thing about winter is that the roads get gritted. You are behind a gritting lorry and you can hear your car getting dashed with rock salt. The next problem is the grit and salt being kicked up and damaging your windscreen. If you leave a crack like this, it...
Force Open The 451 Hatch
If the boot/trunk solenoid or switch fails you will have to open the boot to change them, however, you need them to work to open the boot.
Force Open The 453 Hatch
So, you have no power or the electric boot opener doesn't work. No fear. Opening it is easy. This page covers both the upper and lower hatch on the fortwo. Upper Glass Hatch Opening Easy peasy lemon squeezy. (that's not going to translate very well). Pull the...

Fortwo 451 Roof Damage

Fumes In The Cabin
Have you ever noticed the smell of exhaust fumes in the cabin when driving? Seems odd if you consider that the engine is behind you and you are moving forwards. The Reason Is Two-Fold When you drive, there is a pocket of low pressure behind the car. This draws air...
Fuse Taps
Fuse Taps Fuse taps are clever pieces of metal and plastic that can turn 1 fuse position on your fuse box into 2 separate fuse positions. They are a good generic way to separately power an additional circuit. Obviously I would never recommend these over the proper...

Gearbox Oil & ATF Comparison
I Really Don't Know Why But... There are some normal, intelligent smart owners out there who insist that you can use gear oil in transmissions that are designed and specified to be used with ATF. Apparently the manufacturer of the gear box don't know what's best....
Generic OBD Code Readers
Cheap OBD Code Readers It's a fairly common phrase to be heard said by a car owner with a problem. "I'll buy a cheap code reader and then..." Let me stop you there. Something is only cheap if it works. £10 might be cheap for a code reader but if all it is good for is...
