Does anyone know how to change the dashboard light in a C 280? Or if you even can?

 

It only takes a few minutes and relatively easy with some finesse.

You need an instrument cluster removal tool that you can buy at the dealer or on e-bay. You also need replacement light bulbs you can buy at the dealer or on-line. There are about three diffrent bulb types depending on the model.

Be careful and gentle so you don't damage or scratch up anything.

 

The cluster comes out as one unit as the previous post mentioned. You just need the cluster tool which are basically two hooks to pull out the cluster. You just have to be careful that you pull out the cluster straight out though. If you pull it out on an angle, it may jam and you'll end up cracking the plastic case trying to free it.
