I agree with this opinion. However when this problem occurs, BMW and it's dealers do not replace just the ECV valve, they replace the entire compressor which includes the valve. Here in the U.S. this is a $1,200 to $1,900 job (including labor) depending on where you take the car for repair. This is an extremely common problem in the E60 cars.
