G'day Greg.

To do a R134A retrofit on your vehicle will require a reciver dryer, 2 adapters (for the new style charge fittings), a pressure switch if you don't already have the modified type for Australia, a flush and regas with dye and some oil.

I wouldn't be jumping at a new compressor yet, there are many other seals/orings that can leak(at that are more probable), even the valves in the charge fitting are known to leak.

The dye is pretty good at finding any leak except a leak from the evaporator (W140's do this all the time).

I'm not sure what my dealership charges to do the retrofit (I'm the one who does most of the A/C work) but at least you know that it's done right.

If you want me to chase up the cost of a retrofit then feel free to call me at work (9997 2455 8am-4pm) with your exact VIN so I can get a quote on the parts for you.

Alex.
