Hi everyone,

I have always handled the upkeep on my cars but I never thought about their ECUs. That is, until last year when the weather turned cold here in New England (Maine) and my '05 MB e320 CDI didn't want to start. It would have been faster and cheaper to send the ECU to a service, but far less interesting and fun.

Thanks to all of you who have taught yourselves so much, and are willing to teach others!

Phil
