1991 m931a2 lost air on recovery.

Thanks for the update.

You're one of many that have had this very same issue.

This makes it much easier to help the others, especially when they fail to research before recovery.

The low miles on these trucks is only one reference.

Think of it like this and you may think again. The glass is 3/4 full(sounds like a good glass of water?). The glass was full but has been sitting out in the desert for 3 years(sound like a good glass of water now?).

After i had the issue with my air drier, i had an air leak on the ctis dump valve on a rear axle. tried to find a replacement to no avail. i took it off and took it apart ( very simple valve). it had a piece of metal that looked like a piece of pipe thread stuck under the diaphragm. no cost fix, works great now. there can be alot of crap floating around in the air system.

Anyone have an old C clip from a dryer rebuild on purge valve? Mine went wingen off into outer space. So far can not find one that fits. Thanks in advance.

If you do not have a alcohol injector for your air system, install one, this WILL take care of your air system freeze up problem and add the checking and filling to your walk around..

I'm not so sure an alcohol system would be good with CTIS parts.
