You need a 1/4" drive 10mm universal socket. Every Benz mechanic has at least one.

Ah the 104, I wish that found its way into the W126s and/or a five speed manual.
Anyway, also a socket with a flex head may work too. It is hard to tell from the pics. Also, if you have a MityVac (which I highly recommend!) pull a vac on the EGR at idle. It should stall the car if it opens.

I too used the small 1/4 inch drive socket set with a small extension attached to the socket. I soaked the nuts first with penetrating solvent. If you have access to a MitiVac, you can easily check to see if the EGR valve will hold a vacuum (it should). Mine looked terrible, but worked fine nevertheless. I guess you can clean the EGR valve with solvent, while you had it out of the car.

I disconnected the rubber tube at the far end but let it still connected to the EGR valve. I sucked at the tube und could hear something close (a membrane perhaps) and it held my oral vacuum
![]() Today I was able to open up the pipe to clean with a speedometer cable. Hope that helps a little. I am waiting for parts to do other overhaul, distributor cap & rotor, O2 sensor, spark plugs and SP wires. After that I gonna retake the state inspection. Knock wood!

A MAJOR SETBACK
Yesterday I was happy to be able to get my lambda A/F ratio to voltages between 5.9V and 7.1V, what translates to 0.56% - 0.47% duty cycle. However the numbers are for idle.
Today I measured at 2500 rpm and got reading under 3V at pin 3 of the X11 connector, which means the engine is running too lean, I tried to make it a bit richer and got the following: Idle: 6.91V - 7.75V (0.493% - 0.42%) borderline of running rich 2500 rpm 3.02V - 3.86V still too lean The idle reading should stay within 10% of the 2500 rpm reading, now they are way apart, I cannot bring them closer with lambda adjustment alone. Idle: rich, 2500 rpm: too lean, that does not make sense. What is wrong? what should I look at? Please help! Edit: How to adjust lambda A/F ratio according to Bronzeross Quote:
