I had to creat a new post as I cannot figure out how to PM attachments!!

This is how I did my 2005 CLK EGR delete.

I disconnected the EGR valve on the RHS of the engine and jammed a 5W 1Kohm resistor between the 2 pins on the connector. I sealed both that and the valve connector with tape.
The rest was done in the electronics box at the LHS at the bulkhead in the engine bay.

I'm not sure the resistor values are correct because in the warmer weather I get a P0102 Mass Air Flow circuit Low and Limp Mode. I changed the MAF to no avail and then undid the bypass and it was all good - except I started to get the black smoke. I redid the bypass in September with no problems
I'll look into it in the warmer weather.
