Did this work out okay for you ? .

Mine was snapped off when I bought the car long ago, last Summer I searched junkyards until I found a good used cable and the plastic parts around the control knobs that were also broken or cracked .

There's also a vacuum pod behind the glove box that controls the recirculating or fresh air, this is usually perished, replacing it isn't terribly hard .

M-B sold me the new pod, it had the wrong arm on it and I was able to take the pod apart and swap the arm onto the new diaphragm .

I'm always interested in hearing about 240D HVAC issues, repairs, tips and tricks .
