C240 203.061 several electrical failures
My C240 203 has developed some weird electrical behavior pattens.
Some instruments not working intermittently, central locking issues and tail light failure. In the morning or after a cold start all seems to be fine for a short time. Fuses are all okay. Any help would be appreciated |

Here in the USA, MB issued a recall for defective voltage regulators on most 2002-2005 cars. Possibly changing voltages are causing computer issues.

The rear SAM may be the problem. MB issued a DTB a while back concerning this problem. Don't wait too long to get it checked out. You could wind up stuck with a dead battery.

Thank you for your contributions, I have now changed the rear SAM and my problem is fixed! Has anyone tried to repair one of these wierd things? I am so glad that vehicle engineers don't work on Aircraft electronics, thats all I wan to say.
