I finally got the car back in my garage to scan the codes again,

My scanner isn't a Mercedes scanner, so it only knows a few of the code definitions:

P0100 - MAF/VSF Ckt Malf
P0001 - see service manual
P0507 - idle control sys rpm too high
P1519 - see service manual

I googled and found "CODE P1519 CAMSHAFT TIMING RIGHT CYLINDER BANK SIGNAL RANGE PERFORMANCE." but this is an inline 4, there is no right bank. Googling P0001 says its a "generic" code.

The car idles poorly, but is drivable. I think it probably needs a MAF, do these codes support that?
