Plutoe

Have you charging system professionally load tested and watch out for *****!!

GregMb320

What system are you talking about ??? Sorry but i dont understand what you trying to say ? Can you explain that ? Thanx

Having climatronic you can access car voltage for troubleshooting by pressing few buttons.
Takes Plutoe to need professional for it.
Your symptoms can be interpret in 2 ways.
1. your lights dim because voltage drops,
2 voltage drops because the engine drops to very low rpm.
When observing voltage might give some indications, check car for pending codes and listen if sudden rpm drop is not trigger by attachments like AC compressor, or bad pulley.

Car does not have any codes and pending codes , run s like new ....
yesss im thinking about number 2... Kajtek1, that lights dim becouse engine rpms drops to very low idle for a second or two then without pressing gas pedal and still holding brake at the stop light it goes back to normal by itself .....
So are tou suggest to set my climatronic to voltage and observe it while im driving ??

You are the one behind the wheel. I don't know how good are your senses and what is your experience in interpreting sounds.
When observing voltage does not cost much beside moving your finger few times, if you suspect mechanical resistance, taking the belt off and moving all pulleys by hand would be advised.

Ok no problem i can do this ... I will take a belt of and check ac compressor , pulleys and alternator for any sound or ressistance ,
i also check if this happens only with ac on or either way with ac off plus voltage check , thank you very much
i live this forum and love MB cars , keep spending money but still love them
just did all the suspension plus aligment , what a sweet ride

Plutoe

The charging system consists of your alternator,battery and the electronics that control the system---watch out for make work projects and don't create an unsafe condituion by taking belts off!!

GregMb320

Oook , thank you for advise , i ll check everything as soon as i get home and find some spare time

GregMb320

I noticed this happens while my AC is on only , when i use EC button to turn it off its all good then , so i guess my ac compressor is going out ???
another thing i have some rattle sound on idle prabobly chain tensioner needs to be replaced ....?

kajtek1

AC compressor grinding internal parts will make a noise.
Time to get your fingers dirty.

GregMb320

thanx , i expected that ....
anyone had an experience with ebay compressor , is it worth it ??
i have a vidio with the sound on my phone but dont know how to post it btw
