Not ALL models have super difficult to change evaps, but I'm afraid that your car does indeed. The official flat rate time for the job is in the area of fifteen hours. That's for a pro tech that knows his way around the beast.

Think about it, that's two full days for someone who KNOWS how to do it.

I drove my 300E Tuesday and it was over 70 degrees. After the car sat in the sunlight while I went into vote, the interior heated up some. I just crossed my fingers and started it up. It started blowing ice cold air. I go through this every spring, scared to death that it has sprung a leak over the winter. It looks like I'll probably make it through another summer without having to do this tortuous, and probably frustrating job.

Good luck with yours,
