The following experiments I've done to get the problem under control:
Place LED control unit as far away from cables and control devices
-Entstörspule / Ferrite in series and capacitor in parallel to the supply voltage
-Control Reconnect directly with +/- to the battery
-Control Of daytime running terminal of the light switch (Passat 3BG) and several mass points tested
Disconnect -Standlichterkennungsleitung or on ground
-> It all brought nothing!
Once the lights are, I have no radio reception more and Navi is no TMC signal!
So before anyone installs these bulbs and how do I make holes in the bumper: make sure to first TRY !!!
Addendum: I NEN way found rid the disturbance: RF chokes at the output! The 2..3 meters LED cable generated by the clocked LED driver neat electromagnetic radiation, can be easily verified with NEM simple FM pocket radio. Since both LED modules are connected in series, a plus pin of an LED terminal is internally connected to the minus pin of the other terminal. Reactors must Weil to the unconnected pins, that is, the actual plus / minus terminals, and as close as possible to the control unit, ie
LED output 1 + ---> throttle ---> LED1 ---> LED output 1 - ---> internally connected to LED Output2 +
LED output 2 - ---> throttle ---> LED2 ---> LED Output2 + ---> internally connected to LED output 1 -
