2007 CLS 550 - ECM
Hi all, I am being told the ECM is bad for a 2007 CLS 550. It's throwing various DTCs (P0030, P0050, P0300 - P0304). I've written about this in the past and have done several checks. I'm trying to find a good reliable source (other than the dealership) to rebuild the ECM or for a replacement. Can anyone help? Thanks.

New/rebuild ECU...
To repair your ECU there are Internet companies you can ship it to.
They either replace the bad chips -Or move the E2PROM over to a donor unit. No/little programming involved.
How did you establish your ECU failure what causing your issues ??
