weird cluster lighting problem

**OneBadAudi** · 10-30-2008 09:17 AM

So all of my center dash display lights and radio lights dim and get very bright, then dim again...i cant figure out what it is, battery is good, alternator is good anyone have any thoughts on this.

Thanks
Miles

Have you found any kind of trend as to when they get dim/bright? For example do they get bright when you're on the gas and dim when you're idling? Does it switch when you go over any bumps?

My guess would be to check the connections at the fuse box. A loose connection could potentially cause that.

i tried that to, giving it gas to see if it got brighter and it dosnt,same thing with braking, no difference, there dosnt seem to be any kind of pattern, it just gets very bright, then very dim...

I thought only B5s had problems with instrument clusters going out. Are B6s now developing that problem?

does this issue affect all the interior lights, i.e. cluster, stereo, window switches, etc? and if it does, how are the interior lights affected when you manually adjust them? is the range of light, from being really bright to being really dimmed w/i the same range as what you can set from the manual settings? you may have a faulty connection there...

There is an ambient light level sensor that varies the brightness of the dash lights according to the amount of ambient light, so if there is some bright light shining on the sensor, then due to movement of the car the bright light varies, that will cause the dash lights levels to go up and down. Are you driving when you notice the dash lights vary, or stopped, not moving?

yes i noticed this when i was driving, that would make perfect sense, just didnt realize it made that much of a change in light.
