The outside temp gauge on my 97 e320
reads 10 to 20 degrees too high.
On this site, Barrie advised that the
temp sensor and gauge cluster could be
tested on a w124 by replacing the temp
sensor with a 3000 ohm resistor and
observing a 77F temp reading. Can I
use the same procedure to test the
temp sensor and gauge on this w210?
Thanks in advance for any advice.
