Hey guys,
I've heard that resetting the ECU on a W124 E220 could help the engine in some way...
How do I do it?
What are the benefits?
Are there anything I should bear in mind?

Thanks,
Jeff

You could probably just disconnect the battery for a few hours, then reconnect it. That should reset the computer.

Thanks. Is there anything I got to do afterwards so that the ECU kind of *learns* the stuff back?

ALso, what benefits does resetting the ECU have?

Thanks,
Jeff
