Well written. My '87 300D Turbo (W124, OM603) also had a noisy fan and worse, the early 124s mounted the fan on the under-dash panel, which acted like a drumhead.

I discovered that later 124s use a bracket mounted on the cross-chassis brace so I adapted one for my car. The fan now is so quiet it can be heard faintly and only before the engine starts.

The '87 has no passenger airbag so operations are easier.
