I received some e-mails asking me for the vw retrofit instructions
that came with the kit.
It's only one page in English, and the other pages are in other languages.
I am posting the page in English for your reference only,
in case you are interested in purchasing this kit from your dealer.

INSTRUCTIONS FOR CONVERTING R12 CONDITIONING
SYSTEM TO R134A
Notes:
<>Observe safety precautions when working on vehicles with
air conditioning system => Workshop manual
-Air conditioner with R12
<>Installation set,part No.357 820 794 is required for conversion.
This set contains two adapters (for low and high pressure valves)
and a sticker.
<>Additionally order the receiver (reservoir) including it's O-rings
and the compressor O-rings (from parts catalogue).
Work sequence:
-Extract refrigerant R12 using extraction station V.A.G 1691.
-Remove refrigerant oil from compressor - Two proposals for this:
Proposal 1:
Remove oil drain plug. Push a 200 mm long and 5 mm thick hose
as far as possible into the compressor and extract oil with an
oil extraction pump (for example Fischer Kälteklima,
order No. 823 2251).
Proposal 2:
Remove compressor, remove oil drain plug and tip refrigerant oil out.
