Dealer Will Not Sell PAG Oil

[kornellred]

I went to the M-B dealer (Ray Catena in Edison NJ) today to purchase a drier desiccant element and sealing rings for an impending changeout of the ac compressor in my 2004 C240 (it works fine but makes an annoying whining sound - very undignified). I have a brand-new OEM compressor on hand, and plan to have the job done at an independent shop.

When I asked about getting the essential PAG oil for the compressor, I was told that it was available, but only in the shop. It is not sold over the counter.

I was wondering if this is a global M-B policy or simply a local decision. If the intent behind the policy is to discourage having ac work performed outside the dealer setting, then you would think that M-B would restrict the sale of all of the other AC components in a similar manner.

There are one or two authorized PAG oils besides the M-B branded formula, according to available literature.
