W124 e300d egr valve linkage

[Smiley]

I noticed today that the two sections of the linkage (in the photo below) are not being held together - the two rivet things that hold the sections together are allowing the two sections to move independently - is this correct or has something worn out?

It's right, there should be some slip.

What is the point of the rod - it seems to have a lot of free play in it?

There's a throttle plate just upstream of the EGR inlet which at low loads is partially closed to help draw EGR into the inlet. When you put your foot down, this throttle valve gets opened up, as the EGR is then turned off.

Despite sounding like a bad thing, as it only closes at partial load, it doesn't do any harm to performance. Although I have disconnected the EGR on my car, the throttle valve is still connected and working.

Incidentally, the throttle linkage should be lubricated with ATF (which isn't an obvious choice of oil, but that's what MB say!)

Thanks NC

I bet they say it has to be MB ATF
