Probably has a variable displacement compressor, not the old style on/off, so the engine management takes care of the load and keeps the idle stable. One of the complaints of the old compressors was the banging on and off and engine surging.

The genuine ones come apart with the tube method. Aftermarket ones usually need more brutal methods.

If you have a dipstick tube, you can suck it out and measure, replace the same qty. Do it a few times, and then everytime you change engine oil. The filter on older transmissions was just a gauze strainer, and little point in replacing.

And I would imagine the whole thing would fall apart. But then there is no reason for the woodruff key to break really, unless the nut came lose, but you’dd probably know about that fairly quickly.

Doesnt the bottom pully have rubber isolation harmonic thingy? In which vase it may be broken so the inner is turning , but not the outer. Have you checked if the whole lot has stopped turning, or just the outer.

I would suspect everything before the valve tbh, like freezing inside the drier. But normally if there is a blockage you will see a vacuum on one gauge. Also worth sucking everything out and weighing to check the correct weight as a starting po8nt.

Autodata says 30ml for the condensor and 12ml for the drier, plus of course what got removed with the gas. Yes the oil can be added by the machine, or you can put it in the components before fitting. When the ac stops, is the compressor still turning, and what are the pressures when the ac...

What is wrong witht the expansion valve?

You’ll have trouble getting anything out of those two. I’ll look in my book tomorrow for the recommended amounts.

Recovering the refrigerant may remove some oil, and this qty should be noted. There are also industry standard qtys that are replaced when components are replaces. A decent ac guy will know theses. Its all a bit of a guess, but isnt super critical, just not way too much or too little.

It’s nasty

There’s only 3 screws to frop it out and take a look.

Its got plenty of fresh black paint on it, and shiny shit all over the engine bay.

Sounds like front drive flanges.

Never understood gear oil viscosities, but yes, you have open diffs so dont use anything for limited slip digfs.
