Dashboard Lights Not Working? Troubleshooting Guide

Hi everyone,
In my Passat 3B model from 1997 (with blue interior lighting), several lights have stopped working.
An inquiry with Volkswagen revealed that these parts cannot be replaced individually.
I now assume that the lamps or LEDs are soldered in place.
is that correct?
and if so, where can I get them so I can replace the defective ones myself?

Sure, here's the translation:

'Hello TDI'

"When it comes to the instrument cluster, it will almost certainly be blue SMD LEDs. You can find these at stores like Reichelt or Conrad. However, you should be able to solder, as SMDs are very small. I personally can't, but in almost every circle of acquaintances, there's someone who's a bit of an electronics hobbyist and can do it. You can definitely find the specific part numbers for the SMDs online, perhaps on forums like "passat plus," as there were also some that changed from green to blue, or you could ask on the "Suberb" forums."

Do you happen to have a URL where I can ask further questions?
