Istrument cluster light weak on speedometer only

I have a question about the speedo on my 2003 S500. It works perfectly, but the lighting on the speedometer only is weaker than the rest of the white instrument illumination. When I try to dim it with the knob, nothing happens. On my previous 1999 S320 the light was uniform in all of the gages, so I'm a bit puzzled by this. If anyone knows what the problem might be (or if it is a problem, I'd be very grateful.

this is a known issue with W220 clusters. There are some weak drivers (electronic parts) for the illumination inside the cluster assembly. There are companies specialized for such a repair, and at YouTube you'll find some posts to fix it, if you are an electronic DIY-er.

I think this is somewhat different as the ones I have seen repair instructions for has been a general fault, affecting all the white light on the in all the instruments in the cluster. My problem is different as just the speedo illumination "blocks" that changes with the Distronic or Speedtronic is weaker. The rest of the speedo lighting is normal.
