Has anyone experienced this? I just did a regular underhood inspection and it seems like the refrigerant discharge hose is weeping oil at the compressor end rubber-metal crimp.
The MB part is $53 and would take me less than 1 hour to replace.
What is the going rate for dealer or indy AC system evac and recharge?
Cross posted on all *166 sections until the mods consolidate these nearly identical sections. I used the search feature and it didn't produce a useable result.
AC performance is reasonable, no noticeable reduction in cold air. Outdoor ambient temp 90 deg., AC setting on manual "AC on" set to lowest temp and fan at max, center (face) vent mode.
On the other hand, my wife's BMW AC is like ice coming out of the registers. My GLE has never been as cold as her X3.
I will keep an eye on the hose and see how quickly the leak, if one exists, progresses. The oil residue on the hose was pretty localized and didn't look like it came from anywhere else, for example the oil filter housing.
My GLE is freezing my elbows in 120F ambient
Do system troubleshooting. Good scanner should give you all the data on single page.
Post a picture of the oil marks?
All parts under the hood usually collect some oily film over the time, so even water leak can look like oil.
I checked the hose again and it seems like it is weeping oil. No loss of AC performance yet. I will clean it again and make a decision after our vacation coming up.
The ac line and o-rings arrived. AC still blows cold and XENTRY says refrigerant pressure is within spec.
I think I will wait to replace the hose, probably spring time. The only symptom is weeping oil from the hose crimp.
Can I add oil to the system without opening it? Maybe half a can of refrigerant? Any downsides to doing that? I want to keep the compressor lubricated.

My rule is to never crack open a sealed system unless I'm prepared for all the consequences

You're right, it's wrong.
One downside is over-pressurization - could lock the compressor or cause the problems such as "The only symptom is weeping oil from the hose crimp."
Over pressurization will not lock the compressor as the system has high limit shut off.
The question was about adding oil anyway.
Joe had bad day and that is all.

Wrong again. I had a great day.
But I am puzzled how you can even remotely advise someone to add oil into an auto a/c system without knowing how much to add, much less how to do it.
You do know the oil circulates throughout the refrigerant circuit and too much oil will reduce the effective condenser & evaporator coil capacity, right?
Do you even know the ONLY proper & precise way to check the oil in an auto a/c?
Does the car have POA, POE, PAG, or mineral oil?
Moving on...

Which is kind of like rendering the compressor inoperative, correct? How would you determine which it was - dead compressor or dead system?
Maybe there's a "downside" to just "adding half a can" of refrigerant.

You are TOTALLY WRONG (how it feels on your side?)
I never advised adding oil in the first place. I simply answered the question if adding oil without draining the system is possible.
You have to have really bad day to manufacture speculations like this.

The dead system will not produce any pressure difference.
The overcharged system will fluctuate the pressure.
It will cool, but with compressor only on partial duty, it will not be efficient.
Than with system flexibility it takes a lot to overcharge it to the level of high limit clicking.
Even full can of refrigerant is not going to do it.
