Does the odometer affect the DPF on BMW engines?

BMW driver’s question

I am writing regarding a problem that arose with the DPF after visiting two workshops. I received different suggestions from the mechanics about the air cleaner. One says not to replace it, while the other absolutely recommends it, as it affects the cleanliness of the air intake. Please advise.

The problem was with a 2008 BMW E60 520d with an N47 engine and 250,000 kilometers, but it can also happen in other models.

Freshly replaced DPF in BMW, clogged again in a short time – what is the reason?

BMW driver question

My BMW had its DPF filter replaced with a new model from JMJ. After almost two months, the filter light on the dashboard came on. I filed a complaint with the mechanic, who stated that “the lambda probe and glow plug controller are defective”. After replacing these parts, trying to burn out the filter does not work. In addition, it turns out that the light comes on even without the engine running (on the ignition itself). Does this mean that the filter needs to be replaced once again?

Non-closing door and immobilized mirror in BMW – how to fix?

BMW driver question

Some time ago in my car there was a problem with the right front door. Once they close, once they do not. I have already educated myself a little on where to look for the cause, but this is not where my question lies. Along with them, the right mirror stopped working. I can change the alignment, but when I put it in reverse gear, the mirror should lower, but it doesn’t. Do these two malfunctions have anything to do with each other? Please advise.

BMW driver’s question

I recently heard disturbing noises coming out when moving the steering wheel on my BMW E60. I’m having a hard time locating where the noises are coming from, resembling rubbing rubber parts. I have been searching the Internet for the cause of the symptoms occurring, but have not found a definite answer. I would like to add that the noises are not heard from the start of driving only after some time.

Has your service perhaps come into contact with such a case?
