So i change to new VR and now is sick,fluckering light when drive and no flicker when power windows. Any have this problem with new VR. Alternator at battery terminalas shows 14.1V so charge is good.i have no idea whats wrong

You should try uploading a video, which would give us a better idea of what it really is. It could be a small fuse in the fuse box in the hood, or a bad light bulb in your cluster. Btw do you have C55 AMG or a C32? I'm pretty sure it's harder to replace the cluster lights on the C55 than the C32.

so i make a video whats is wrong , and noticed when drive also when power windows the motor make unconstat noise same as flickering... sic... all happen when new VR is instaled in alternator. i go to car electric and they told me 3 guys look at car and from the voltage alternator is ok, but this things happen when i drive ;/ not idle. Strange thing happen and i dont know what to look. probably i buy new VR and check or go to MB to search the problem

Looks like your LCD screen panel seems a little worn out and faded at the bottom. It could either be connection error from there or a cable. I'd check out all the fuses before trying anything else though.

Yes is faded but actual in Poland is over 30 degre heat. So in normal temperature display is ok. Only pulsate is when i drive i check the fuses today and all looks fine. I think this new VR is damaged. I look under hood and other issue may be there and connected to VR my acesories belt is vibrating when idle and more shakin when rpm increase. I noticed my crank pulley wobble and tensioner take it but vibrating/ shaking belt its something new to me. Damn

May I ask where you have gotten your VR?

SilverQum

sure it Hucko aka Hitachi for OE Valeo https://www.trodo.eu/alternator-regulator-h-co-130734

Strange. It might not be OEM, but seems like a sturdy product. Did you get it used?

SilverQum

Nope, its brand new with 5year warranty. 14.1V when idle at battery terminals and with higher rpm same 14.1 no drops

I've done some digging, and I've found the same issue on non-AMG cars. Replacing the battery seemed to do the trick, if you haven't done so. If that doesn't work, it looks like you are having a wiring issue. If that doesn't work. I would have a professional have a professional look into it, but If I were you, I'd try to avoid the speakership as much as I can as its going to be costly.

Thanks. ill check battery, so i swap it from my SLK should work well its a brand new also, then i go to the service to lift up car and check wirings. and if that not work i probably end up with new alternator ... some cost be generated but sleep well then.When i find solution shere here meyby it help.

Hi guys,i ended this problem by rebuild/renew alternator.All electronic in car are good,wires,contacts,plugs. They say worn out of the shaft in alternator and they use old VR says its better.hope this help someone in future.
