Error “Exhaust gas recirculation system. Air volume too low” in BMW – how to fix?

BMW driver question

I have a problem with my car. The car suddenly didn’t want to drive, to the point that it was blacking out. So I went for a computer diagnosis and the error came out: “Exhaust gas recirculation system. Air volume too low.”

The mechanic concluded that there was something wrong with the EGR and unplugged such a small rubber hose with a vacuum. The car’s misbehavior and stalling as if by hand went away. The hose was plugged.

My question is, what now? The mechanic stated that I can drive like this for now. The most likely thing to clean is the EGR, however, they do not give a guarantee that this will help. I did not want to leave the car at them. Once you repaired my car, it was my previous BMW E39. I prefer to bring the car to you and have peace of mind. Have you guys had this case before? Will cleaning the EGR help?

The problem was with the BMW E60 525d, but it also occurs in other models.

BM Cars service response

The problem you described occurs very often in models with diesel engines especially after high mileage and in cases where the engine intake system is not properly serviced as part of routine maintenance. As part of the EGR exhaust gas recirculation system, soot particles and (in the case of a malfunctioning scavenger filter) also sizable amounts of engine oil enter the intake system. This mixture causes the intake system and EGR components to stick. The intake system should be cleaned regularly, and the air cleaner filter should be replaced at least every 100,000 kilometers of mileage.

In your case, cleaning the EGR and intake system can, of course, help, provided that the EGR regulator itself has not been damaged.
