To all
Had my evaporator temp sensor replacd by MB Pentagon Southampton this W/E at a cost of £96 after lots of internet searching. All is well now AC works fine, So if you suffer from loss of air flow after a short period of use would recommend that you get Evaporator temp sensor looked at. March 1998 SL320, sensor was found on passenger side of dash not drivers side as detailed in MB diagrams.

Hi Malcom
No not cool running but loss of air flow and at time of loss of flow any increase/decrease in temp or repositioning of air flow would not work unles car was stopped for 30-60 mns then all would work OK again for a short period of time.Using A/C diagnostic feature found test No 5 evap temp sensor reading 25 deg C when temp in garage was 3 deg C and therefore sensor temp should have been the same.

Lui.

Thanks lui, we have had a few 129 cars with this problem, and I am sure that mine was getting bad when I had it.

Thank you for posting back
