Leathermang, perhaps a mildly clogged condenser? I mentioned this to Zulficar and he wisely advised me to check and clean the fins on the condenser - I did and took off the fans, cleaned out the bottom and in between of the condenser and radiator. Every so often I maintained those as well.

When I got the car about three years ago. The evaporator was leaking, I have always been afraid that the P/O may have put some type of sealant, could that have caused something like that and not show up when looked at with the pressure gauges?

My knowledge in A/C is not ample, but I have had two A/C people plug in gauges and they say that they look fine. The pods have checked out Ok - and I still have the issue of when hot there is a temperature fluctuation of 20 degrees more or less out the vents.

I have observed that when the car is stopped for a while - the hose that comes out of the expansion valve is barely cold and or sweating. On other w124's cars I have seen that same hose is frozen.

As always your advise is much appreciated.
