some of you guys may have read my previous thread about a few things i noticed with my newly acquired 99 e300td. one of the issues was a P0243 code, which is "turbo/sup wastegate solenoid A malfunction"


i reset the code and changed all the vacuum lines then, and yesterday it came back.



am i correct in thinking the next possible problem might be in the vacuum pressure converter valve that the vacuum line coming from the vacuum actuator on the wastegate?
