It would appear that the hose simply "Let Go" and you were wise to shut-down
the compressor. It will also be prudent to repair ASAP as MOISTURE is the AC
systems WORST enemy. That's why there is a "DIER" in the system that absorbs
minuute amounts of moisture from the system. You can well imagine how much
moisture you've got in your part of the country.The Hose will cost you
approx $80-110 dep on which one quit. As far as switching systems to R134
refrigerant, now would be the ideal time to do so.If you still have the
"original" compressor it's probably on its last leg (We're selling many this
summer) There was an article in the July Roundel BMWCCA magazine RE:
Compressor changeover to R134. It involves replacing the outdated Bosch-Behr
wingcell compressor with a advanced design Japanese ( Oh I know the purists
will HOWL over this one !! A Jap compressor in a BIMMER! E-Gads Gavoltz)
Well unless you've got a REAL FAT Wallet FORGET the German Compressor &
swallow your pride. The net result is a Kool car w/o hassles and a
Bullet-Proof Compressor for 1/2 the $$$$$.

Bottomline: We have the retrofit conversion kits for all BMW's to replace
blown or worn-out compressors. R12 kits (it cools better than R134) from
$325, and the kits for the New R134 Refrigerant from $475 (includes R134
drier& expansion valve)The kits contain a NEW Compressor, Mount & Drive Kit
& Hose fittings to hook up. We've sold over 100 kits so far this summer.
They flat WORK. The Diy'ers have had no trouble putting the parts in. We do,
however, reccomend you have an AC professional do the evacuating &
recharging of the system. Do'nt forget to ASK them to SAVE & recycle the
refrigerant they take OUT of your system. This is now EXPENSIVE stuff. Some
shops will try to steal your old stuff. Keep-em honest by mentioning in
advance. This tip can save you $25-50 in Freon charges.

Anyone not getting Roundel BMWCCA magazine E-mail me & I'll fax you a copy
of the article. & BTW anyone not belonging to BMWCCA wanting to join ($35 yr
Bargain of a LIFETIME) E-Mail me & I'll send you an application.
