Wind Noise
Symptoms
You may find your Mercedes SL107 suffers with excessive wind noise or drafts from either the soft or hard tops at cruising speeds.
Diagnosis
Running along the inner edge of your cars’ soft top are 2 cables. If these are broken then wind noise will increase as wind passes into the cockpit.
The Cure
For soft top: replacement hoods are really the only effective cure
Hard Top: The first thing to check is the chrome trim alignment. When the top is sitting on the vehicle, these can be realigned to remove associated wind noise.
Both: In addition to the above fixes, both the driver’s side and passenger windows can be adjusted to fit more snugly and reduce wind noise.
