Hello,
I hope some of you clever people can help me out?.
I recently purchased a W140 1998 S500. Slowly, I am trying to sort out the various issues on the 150,000 miler.
One of the main problems is the A/C not working.
The Vehicle from what I can gather has been stood for some time. So the first thing was to check the A/C and the system was empty. So, I leak tested with OFN, purged it, evacuated and re-charged with refrigerant.
I then cleared the error codes which were emission sensor and some filter codes. I did have to replace the Emissions sensor as the fault kept coming back up.
The compressor runs, then after around 3 minutes, it stops and will not kick in again. Switching off the engine and waiting around 10-15 mins, the compressor will start again and run for the usual 3 mins.
*I am at a loss as to why it is doing this?.
*No Error codes come back up!
*When the dash is set to LOW - LOW or 14 - 14 warm air still comes out of the side face level vents (not ambient air).
At a moderate 19c ambient I am getting
33.6psi(g) Low Side
190.7psi(g) High side
(When the compressor initially runs)
Any suggestions welcome please ? and I do not mind the suck eggs.
