First look at your EGR valve. Is there a hose missing? If so this is likely where it is supposed to go.

But if your exhaust manifold has no EGR valve then some previous owner has swapped your exhaust manifold for a Euro version which has no EGR valve. This is a popular thing to do on the M110 if you can find a Euro manifold. They came to the US on gray market cars so they are not everywhere, but a lot of 280sl were imported this way and none of them had EGR valves. So when they hit the scrap yard savvy Mercedes owners know to grab the exhaust manifold.

Just more of the usual fiction. As always, an Idle mind is the Devil's Playground.
