7l/T1 Touareg Cluster backlight diagnostics 

Hey, on this one I wanted to keep it factory as it was someone else’s and didn’t want to make repairs complicated in the future for someone else. The backlight worked for the center screen as well as the needles but the gauge background wasn’t working so you couldn’t see rpm/speed/ect. while driving at night. If wanting to switch to white get rid of the ccfl bulb that I popped out near the end and stick a LED strip that’s the colour of choice. The issue with that is you’ll need an external 12 volt power for the led, ideally hooked into the cluster dimmer switch.

i like the cellophane idea, I'd try the transformer first but I'm not 100% sure

I havent personally but the LED's will be soldered to the board, Id be curious if its a bad solder joint as usually LED's last forever. The speaker i could see being burnt out though. Few options id consider is 1:Replace it with a used cluster (if you dont mind mileage being out) 2:Use parts from the used cluster to fix yours if you can solder, or 3: if your located in the US look up Clusters by Litke LLC and see if he would be able to source parts/repair (hes well known in the mk4 golf/jetta groups)

Ebay/aliexpress Touareg VOGT Transformer should come up with some options, something like this www.ebay.com/itm/154751414983

You’d need external 12v power for the led strip, and might loose dimming capabilities

Just the cluster face? I’d imagine as long as the spacing is the same I’d think you’d be alright
