I've been meaning to post something about this for some months now but I wanted to check out the FAQ on riocar.org first. The dimmer on my MkII used to work fine but I noticed some months ago that the dimmer has stopped dimming. No matter what the %age is set to the display stays at 100% brightness. Could this be a faulty capacitor? Are there any test points that I should check the voltages at? Any help would be greatly appreciated. Apologies if this is in the FAQ somewhere but I couldn't find it.

TIA
