Sterowniki FRM BMW

BMW driver question

My comfort control module is damaged, if you can call it that. Can the controller from another vehicle in the same series be reprogrammed so that all components work? At the moment, everything that should work does not, and the rest “lives its own life”. If necessary, I will bear the cost of programming. Please help.

Engine waviness vs automatic transmission oil change in BMW

BMW driver question

I am writing regarding an oil change in the automatic transmission in my BMW. I want to change the oil with you dynamically, what is the price of such a service? And the second important thing you need to diagnose a problem, because on the cold box ripples revolutions. When it warms up, it works properly. Will an oil change help? Perhaps the converter or something else needs to be replaced? Is there a chance to diagnose the problem before changing the oil?

The problem affected the BMW 530d E61, but it also happens in other models with automatic transmission.

High oil consumption in BMW 5 – what could be the reasons?

BMW driver question

I would like information on the steps and pricing you use when you want to repair an engine. I am in a situation where my BMW 5 is “taking” oil. From what I have heard from several people, the engine needs to be replaced (some kind of defect). Is it immediately apparent that such a replacement is necessary? How could you help/advise in such a situation? As a last resort, how much would it cost to price and replace the old engine (if it was needed)?

The problem was with a 2012 BMW 550i F10, but it can happen in other models as well.

BMW driver question

I would like to ask about the topic of engine temperature: earlier I noticed that the oil temperature pointer turns slightly to the right when driving harder. Today I was also using my car a little harder, and after arriving home and turning it off in the garage, I heard that suddenly as I got out of the car, the engine cooling (fans in the front) turned on, at full speed. This alarmed me and I spent the 3 minutes to go into the hidden menu and check the temperature reading:

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.
