Hashtag Jacking Points
It might not be surprising but the jacking points are underneath the car. Front If you look at the plastic side skirt, you'll see a small indented triangle. This indicates the centre of the jacking point. Instead of a jacking point, it's a jacking seam. Most scissor...

454 Forfour Dash Pod Fitting
Buy your dash pods. Good luck finding them. The pods themselves connect to each other with a couple of plugs once fitted and the longer wire seen in the picture connects from the temperature pod to the existing wiring loom of the car. The pods fit onto pre-prepared...
453 Forfour Exterior Boot Panel
Remove the internal panel to reveal holes leading to 4 Torx30 screws. I would STRONGLY recommend using a magnetic screwdriver because if you drop any of these and they fall into the boot hatch, you aren't getting them out and they'll rattle. Inside screws......
453 Forfour Internal Boot Trim
Open the boot (you don't need a guide for that, right?). Look up into the hand grip and you'll see a Torx20 screw. Remove it. Grab the panel and start pulling all the way around. It's only held in place with 8 clips and 3 pegs. To refit it, just line it up and give it...
453 Active Brake Assist Fault
You get in your car, start it up and get stabbed in the eyes with a big error message about the active brake assist being inoperative. You click OK and the message goes away. However, there's still an error light showing on the speedo. The issue is the front radar...
453 Steering Angle Sensor Removal
Disconnect the battery and remove the steering wheel. Ensure it is straight as you do this. Lift up the top steering column cover to unclip it. Look underneath the lower steering column cover to find the 2 securing bolts. Remove them. Pull the lower cover down and the...
Roadster Side Skirt Removal
This is the standard non Brabus side skirt. It's more of a finishing panel. Grab the bottom of the skirt and pull it down all the way along to disconnect the 6 clips. The pull the top of the skirt sideways all the way along to disconnect the fixings. Too easy. These...
Fuel Pump Failure
This page covers all ICE cars. It's more generic help and some parts may not relate directly to certain models but it'll give you an idea of where to look and what to try. My Fuel Pump Stopped Working The knee-jerk reaction is to just think that the fuel pump has...
Fortwo Alloys On A Roadster
This is a bit of a divisive subject. On 1 side you have people who don't think about it and just fit them. On the other side you have people who staunchly oppose such things because it's either dangerous or blasphemous to degrade your superior Roadster with wheels...
451 Cabin Air Recirc Motor Noise
Clicketty Click Click Click Click Car's on, recirculation button pressed. Lots of plastic clicking noises and then silence. The problem is the motor that drives the recirculation flap. It sit's on top of the cabin heater box inlet pipe which is over on the right...
451 Boot Hinge Pins
The 451 is getting old and despite being hidden away, it's becoming more common for the boot hinge pins to rust and snap. Firstly we need to detach the boot from the car to get reasonable access to the hinges. Undo the boot straps on both sides by removing the Torx40...
451 Drop Link Removal
The 451 drop links are fairly easy to remove (unlike the 450 fortwo and Roadster). They look like this, see below. The silver one is standard and the black one was the replacement. You will need a 17mm ring spanner and a 5mm allen key, however, a 17mm ratchet can also...
452 Drop Link Removal
The drop link connects at both ends. One end to the anti-roll bar, the other to the wishbone. The anti-roll bar connection is generally not a problem as it can be held with a spanner (46Nm on refitting). The big problem is at the other end. The position of the fixing...
451 Boot Side Net
Did you know that a net was available for the pointless removable alcove in the boot? It was available from smart along with a boot floor net. See 150 below. The smart part number was A451 814 00 07. This is the part we are fitting. It's fairly basic, you may be able...
451 Baggy Door Pockets
My girlfriend used to borrow one of my 451s to run around in. She remarked that the door pockets were a bit loose. Well..... yeah! she was stuffing an over sized water bottle in the pocket so the net was being gaped more than a double penetrated porn star. Unlike the...
451 Airbag Controller Removal
The 451 air bag controller is a pain to get to, much like all of the other smart models I guess. You need to remove the lower dash board and the centre console cover. The air bag controller is sitting right in the middle. Since we are playing with air bags, at least...
450 Steering Tie Rod
The is the steering rack from a 450 fortwo. It's unique on this model as it has a steering damper (the shock absorber in front of the rack). However, other smart steering racks should be the same but without the steering damper. The ball joint end of the steering rack...
