Have yours Custom Rebuilt. This is a craftsman level custom rebuild. Because we do all work, we can only take on several projects per week. THIS IS A REBUILD SERVICE ONLY(you must provide your own unit).
it is as mentioned, and made by the company as noted on the Mercedes Manual...however, the only difference is, it is a about 1/8" shorter than the original Idle Control Valve, and I have had the 450SEL since new, in 1979. not sure why that is...but it works fine...
EXCEPT: The problem I had with the original Valve, remains...IT DOES NOT "KICK DOWN" WHEN IT SHOULD...YOU HAVE TO EASE OFF THE GAS, AT 3000 RPM, BEFORE IT DOES...(AUTO-SHIFT).???
