Hello everyone. 2005 BMW E60 5.30i M54B30. This is how the rev indicator moves. There is no malfunction in the car. When you connect it to the computer, it doesn't exist. The car's maintenance is complete. He has no problem. The engine power is very good. Fuel consumption is very good. Transmission oil changes regularly. He has no problem. The throttle has been cleaned. Maf sensor has been cleaned. The DISA valve has been replaced with a new one. Rolant valve was cleaned. The car in the video does not belong to me. Video of a car with the same problem. My car is 148000km.

My only problem is that it works slightly shaky until it heats up in the rolling and such a meaningless movement of the rev indicator. What could be the problem

Good luck tracking that down. It took me 3 months to find the issue with my friend's car and that was after him taking it to the dealership 2 times. It ended up being the compressor causing it. There's many things that will cause that issue just need to isolate the problem.

The air conditioner sometimes did not work. Yes, it is likely to be from the air conditioning compressor. Thanks for the reply.

What other reasons could there be? Does anyone have an idea? Where or from which pipes can the air leak be the most?
