Hello, about 2-3 weeks ago, I became a user of 206. I haven't had a car other than the Tofaş group for 10 years, I paid 3000 TL for the cylinder gasket and oil change due to water loss 2 days after I bought the vehicle. At the same time, the stop lamp and the oil filter flashed. When I stopped the vehicle, everywhere was smoke. The oil exploded in the car. After I had this done, the car stopped at the lights while going on gas and the speed indicator was not working. I fixed it by having gas maintenance for 30 TL, right after the gear was a problem, gear 3 I can't move it to another place this week. I'm going to have it done this week. I can't drive the car comfortably. It feels like it will break down at any moment. There is no problem when the car is running, there is no problem, the fault light etc. It also does not come on. It has a nice transmission. what to care I need to pay attention, for example, apart from the things that the mechanic looks at, you'd better take a look at this brother, etc. or avoid big expenses by spending small expenses, such as oil, cap, sensor, etc. If you can suggest what I should do, I would appreciate it if you help me, thank you.
