What is the solution for BMW 5 Series shaking when the air conditioner is turned on?
2 Answers
Compressor internal electromagnetic clutch slipping or damaged, in this case, the compressor needs to be removed for inspection and repair. Check the tension degree of the compressor tension pulley and whether there is any damage. Over-tightening or over-loosening will cause the air conditioner to shake, adjust the pulley to the normal degree.
I've been driving a BMW 5 Series for many years and used to have this annoying issue where the car would shake whenever the AC was turned on. It was especially noticeable on the highway—the steering wheel would vibrate as soon as the AC kicked in. After some research, I learned that when the AC compressor is running, it increases the engine load. If the engine mounts are worn or the ignition system isn't properly matched, it can easily cause shaking. I tried checking the belt tension and even replaced the spark plugs myself, but that didn't fully solve the problem. Eventually, I took it to the dealership for inspection, where they found severe wear in the engine mount bushings. After replacing them, the shaking reduced significantly. My advice to fellow drivers: don't ignore minor vibrations. Not only do they affect driving pleasure, but prolonged neglect could lead to component damage. During routine maintenance, just ask the technician to check the mounts and compressor connections—BMWs are precision machines, so professional handling is key.
