Refer to document by BenzWorld Member jnash: http://www.benzworld.org/forums/w210-e50-amg-e55-amg/1345786-how-repair-ac-system.html

This document has 15 files that contains PDF pages from the official M-B workshop on how to:

  • Replace the compressor,
  • Replace the dryer,
  • Replace the expansion valve.

Also included are oil capacities when replacing all components or individual parts such as just the expansion valve.


Evaporator Temperature Sensor Replacement Video

If your A/C suddenly starts to blow warm air, your Evap Temp Sensor may need to be replaced. If your S class A/C works for 10 minutes and then dies, and if this behavior continues every time you reset the A/C faults (video shows how to reset errors), you most certainly need to replace your Evap Temp Sensor.

You should also replace it as a very cheap maintenance item if your mileage is above 100,000 miles.

Part number is 220-830-07-72-M6 - you can purchase the Behr model from Pelican Parts at $16 as of 8/24/2019.
