Hall effect sensor w124

[BillyW124]

Evening Chaps,

Why would i have a hall effect speed sensor at the back of my speedo when i dont have cruise control?

Any one any ideas please?

The Hall Effect device behind the speedo is also used to freeze the OAT display when the speed drops below a certain point so that radiator heat whilst taxying/standing doesn't lead to a misread.

That is quite Plausible, Would there be other reasons for this maybe?

..easier to retrofit tempomat perhaps?

Possibly, and I would have thought not worth the fag of having many different assembly set-ups on the line.

Stereo with GALA?
