Hello, i am new here and this forum has help me alot.
So i have c220cdi 2002. It has weird electrical problem, all interior, dashboard and outside lights starts to blink every 30-60 sec. There are no error codes and no battery warning on dashboard. What i already did to car is oil change, maf sensor, air filter, transmission oil change, battery change, tested alternator and everything is fine. So did anybody have this problem or know solution to this?

I would take this to someone with a STAR scanner and see what they come up with.

marcelsvj

First thank you for your reply, and sorry i forgot to mention that i already did that and was nothing wrong with car.

insame1

So you had it scanned with the Mercedes code scanner and it picked up nothing. I'm not doubting you but I find that hard to believe.

marcelsvj

i know right. when i told mechanic about blinking lights he connected scaner and run all kinds of test for electronics. he tested radio, driver windows commands, rooftop commands, calibrated air fans etc. and everything was fine not a single error. it is not really a car breaking thing now, but it's very annoying and i have feeling that something else might break.

You still have yet to answer my question.

marcelsvj

sorry, mechanic only used this scanner.

insame1

That should work. I am guessing there should be at least stored codes though. Might be worth your time to have the dealer scan it and get the print out from them.

have you checked the SAM units front and rear for corrosion. Also have a look at the grounds.

marcelsvj

no i have not checked SAM units or grounds.
i have appointed another check at mechanic in couple of weeks so will do what you said.
thank you for your time, when it's done i will post updates.

My hazzards wont stop flashing and more wiper related problems alarm keep blowing fuses
This sam unit bad ?

Are those pictures of your sam unit?
It obviously got wet and would need to be replaced as that corrosion is just asking for problems. Also would want to check out anything near that as well as the wires for similar damage.

insame1

do you really have to ask?

wilsonwilson21

Kinda gotta ask its expensive to replace and im not a mechanic

wilsonwilson21
