Hi All
Great forum. It's provided me with a lot of help in choosing and fixing my 230E. So for my first post I'm contributing this basic info which I battled with at first. I hope it's helpful to others.
For anyone who's cruise control isn't working and wondering how to get to the cruise control amp under the dash this is how I did it on my '92 W124 230E manual (Being South African this is a Right hand drive vehicle)
To remove the kickboard under the steering column
1. Put your finger into the side of the ignition key hole, you'll feel that the material is made of rubber, pull firmly to the right (the plastic lugs behind the plastic trim aim to the left) *Maybe it's the other way round on a Left hand drive vehicle* and the ignition cover should come off (note the three black holes in the pic below, that's where the lugs snap in) Remove the screw and bolt that you can see in the pic.

2. Now pull the Headlight control knob out, this was a bit difficult but you can do it with your thumb and index finger, I got it out by turning the headlight knob all the way to the left and then pulling it out.
Once you've got it off
3. Remove the nut shown in the pic below. Best to take out the little lightbulb first so you don't break it.

4. The black plasic trim clicks out if you pull to the right.
5. Now you'll see 3 brass bolts that need to be removed. Bear in mind that the two screws you can see under the parking brake release DO NOT need to be removed, NOR does that tricky looking screw that you can see when you pull out the parking brake release.

6. Now down at the bottom under the dash, (easy to find, no pic necessary) remove the two bolts on either side and the screw in the middle
7. Now gently pull the dash out and you'll see the cruise amp box (the silver aluminium box in the pic) you do not need to unscrew the two phillips screws, just unbolt the bracket, the two nuts holding the bracket are visible in this pic. For reference the round thing on the right hand side of the pic is the headlamp knob

8. Now you've ubolted it pull the cruise amp towards you and gently release the 14 pin connector from the back.
9. The circuit board is encased inside the silver aluminium box, you'll need to gently prize the kinks open to get the board out.
10. Go ahead and do the resoldering or cleaning of the board and good luck. I don't have the skills to resolder so I gave the board a cleaning with surgical spirits and a tooth brush but to no avail.
11. When you reassemble it's best to reverse the order, so start by bolting in from the bottom.
Good Luck
