This was happening ever since I had the car and I don’t know whether it’s serious or not. When I start the car, change gear to Drive or Reverse, and start moving away (usually slowly on the brake rather than with gas), after a short distance (like 2 car’s length) the car makes a buzzing sound that lasts about a second. The faster I am moving the shorter it is. There is no vibration, just the sound. It sounds similar to the judder I had before that was fixed by changing CVT fluid recently, only much much more gentle than the judder. Also judder was related to moving away from a stop. The gentle buzzing noise I am talking about now only happens first time when I change to the gear. As long as my car is in Drive the sound never repeats no matter how many times I stop and move away. However if I stop and change to Reverse it will happen again, and then when I change back to Drive - again. Every time I first engage a direction. What puzzles me the most it is not immediate when pulling away. It only occurs after I start moving the car. That is, when doing a tight 3-point turn (when it’s actually a 5 point turn) it won’t come on after each change because the distance driven between changing direction is too short to cause it. Only when I finally move away for good it sounds. When I move away with accelerator I think it comes on but lasts shorter, however I can’t be 100% sure as the sound is not loud enough to hear it with revs. My mechanical knowledge is next to nothing I am sorry if this problem is obvious or has been answere here before, I browsed this forum before but couldn’t find exactly the same description. I am interested to know whether it’s serious as I intend to keep the car for a few years. Thanks
