I have this code p1422 on my 01 s 600. It has a
100,000 miles. Can't really find any solid leads. Ideas please

i have the same problem. The code description is elusive... anyone have info?

well, i've called Mercedes and they confirmed it's definitely a Secondary Air problem. On another web search, i've narrowed it down to the Secondary Air Injection Solenoid Valve short to plus side. But, this car's got 2. lol

Guess i'll just swap one at a time with a known good solenoid and see what happens.
