When AB filled the a/c gas, they filled too much, so pressure too high. Anything above 250psi will cause the a/c to blow hot air. Apparently, with BMWs, the pressure not easy to adjust, and sometimes on meter, it shows pressure 250psi, but actual pressure is about 400psi for some reason after a run. When pressure too high, any very small leak will blow a big hole. After that, major problem, cannot solve with gas anymore. Any leak in the cooling coil have to change cooling coil. If you have to change cooling coil, the entire dashboard have to be removed. After removal, dashboard no longer the same - apparently dashboard is built in a way that removing destroys certain clips, and after that definitely have sound. I have a 325i which BMW service centre removed dashboard - almost completely destroyed, cupholders broken, aluminium strip bent and stained, other things cannot see, maybe a lot more damage under the dashboard. Apparently, this is the post-mortem story done by an air-cond specialist that I visited. Nobody dares to remove dashboard, but when a/c rosak or cooling coil needs to be changed (every 5 years I am told), BMW service centre will wreck the dashboard, in many cases beyond repair, so they use super glue, silicon, etc. I had an experience once my door panel was removed, they broke the plastic, and used glass silicone to stick the panel together - when got into the sun, the silicone melted, and I was jumping mad when I found out what they had done! That was AB Segambut too.</p></blockquote><p></p>
