Kinda a newbie on here. An off the wall question here that i am not sure how to aproach. I have a 2004 MB C230. I have been having altenator issues. Everything was showing altenator and battery issues. One day driving to work I lost all power and started having a rough engine. I went to park the vehicle and once I parked the engine started to work normaly. From everything I know that does not indicate a alenator problem or battery.... To me that says a electrical problem with wiring or something like that. I heard a few diffrent ideas. I was involved in a rear end collision a year or so ago. Where the car should of been totaled. ( my insurance company decided it was better to fix than replace.. CRAZY expensive on there side!) Other than that been great. PLEASE help!!

0620 and 0562 fault codes

 

sounds a lot like an alternator to me mate. Have you had the charging system checked?

 

I have not. I guess I will get it checked at auto zone tomorrow. Just a battery and alternator check right?

 

Yeah thats all, they should do a charge rate check.

I could be wrong (it happens about once a year :P) but if my customer told me that, the first thing I'd do is an alternator charge rate check.

 

Ok I will check. Just the way I put it in park and everything returned to normal just didn't seem right. Cause I drove the rest of the way to work no issues. Thanks

 

yep I understand your reasoning for sure, but for the cost of nothing, get it checked and then you can say... its DEFINITELY not my alternator.

0562 is low voltage
0620 is alternator not charging.... as for why it's not charging is another story. If you stopped and then took off afain and all was good, I'd consider a wriggle test of the plug on the back of the alternator while holding a multimeter across the battery. A charging battery will hold steady at 14.xx volts while running and drop to 12 when off and lower when being discharged by car without alterntor charging (hence you 0562 code)

 

Will let you know what i find out thanks!

 

How old is the battery ?. A battery load check would be helpful.

 

After the hockey game I am going to go check at auto zone
