Hang in there Bigpete123,
So far you've mentioned the repairs I've done (and the repairs I intend to do) on my E320 of the exact same problem. Because of that, I just saved tons of money. Seriously, thank you very much sir.
I don't have much to share with you regarding the repairs I've had done because you've already done more than I have. Truth is, I'm just waiting for the outcome of your catcon replacement. Please post the results of that as I, too, am just about ready to give up and buy a low-maintenance Japanese car.
