Another 0.02 cents. . . .
Lockman, there are some variations on these alternatives:
1) if you really want to sell the car, then charge the system, don't add uv dye, and sell/trade it in. Buy a newer S class car, not necessarily the S600 series. A later 500 would be ok.
2) if you want to keep it, then try a leak sealer such as described in my web page (click 'www' icon below) under Menu #16. If it's a small leak, then it will stop it and may work for many years. If it doesn't, you've lost nothing since the system needs rebuilding anyway, so this is precisely why leak sealers were invented.
Of course, there's some pros/cons of using this but in your and my situations, it was right for its use.
