Hi everyone new to the site so first post. I've just bought a c180se kompressor auto and it didn't have a manual. I roughly know what most of the knobs and controls do because I had a older merc before but the auto button for the air con is doing my head in it keeps switching itself off after a short while. Is that normal (surely not). Seen the post a guy called Glyn posted to direct you to the site where you can download your car's manual but I can't find my car on the list.
Can anyone help:-?
