Good evening. I own a 5 series, E 60, 2004, 2.2 petrol. It does not idle, on the test there is a problem with cylinder 3, I changed the coil, the compression is at fem on all cylinders! the spark plugs, vanos, disassembled the pulley, rectified, rebuilt the valve seats., the problem persists. On the move there are no problems, the car pulls. Could you give me some advice?
