Some problems about my 307 vehicle

I am generally satisfied with my vehicle, but I have expensive problems, I do not know what the problem is, I am thinking of going on Saturday, I do a lot of roads and there are constant problems (100 km / day)

When I go between 100-120 with my car, the steering wheel trembles when I press the brake, it goes off when I pull my foot, it decreases gradually when it slows down. I went to Ankara Erkay twice, firstly, the disc was changed to the pad + front and back, he said there was a skew in the disc, but the same thing continues with the brake at high speeds, the tremor did not pass,

Another issue was that I went to erkaya for maintenance, my vehicle was maintained at 102,000, they turned the disc back to the disk, air, pollen diesel oil, etc. changed, started to warn that there is water in the diesel filter 2 days later, I even complained about what I bought diesel continuously, nothing happened, erkay changed the diesel filter, still warning that there is water in the diesel filter.

The other thing is when the vehicle is at idle, there is a sizzle from the glove box, because it is thin, but it is empty but not continuous, in a moderate way,

Finally, the volant in my car had to change, so said the man, he shakes a lot while stopping the car,

I guess it is small problems except the flywheel, should I go to the service, whenever I go to the service, I get on again for 5-6 months. What could this tremor and sizzle be?

Can the disc, the rim, the bent (not possible) tires be problematic, or are the other things at the front problematic?

I think the crunch of the torpedo coming from there might be doing the pump in the fender, something is working there, but I don't understand what
