Hello,I bought me a BMW E 39 Bj 2000 530 D. Unfortunately I have to find out that the vehicle ratters between about 100 and 125 km. Not the classic rattling on the steering wheel but on the complete vehicle.It is as if you drive over a bumpy road and only in this km/h area.Can someone help me and tell me what it might be.In the workshop I was already and they are just as baffled as I am. I thought at the beginning that it might be an imbalance on the bike could not be the case. I am grateful for all the tips and say thank you to everyone. P.S the vehicle is an automatic and it happens in 5 gears at low speeds. I am really perplexed.Only when accelerating with winter and summer tires. What can that be?
