Hey guys, Sorry to bring up this old post.
I have the same problem with the SAI system. Both P1410 and 1411 codes are on. The OEM check valve and change over valves are expensive.
Particlewave, I know you confirmed the Mercedes MTC3095 was a perfect fit for the check value in 986. Can you confirm if the mercedes part for the change over value is also a good fit? The part looks different. How did you make it fit? Do you have pictures you can share?

Also, any update on your little hack on fooling the DME during cold starts? do you have it up and running?
