Peugeot 307SW HDi FAP 110 2.0 – Motor squeaking

Hello, I have been driving a Peugeot 307 SW HDi FAP 110 2.0 liter for 10 months now. EZ: 08/2003. The following problems could not be solved: 1. Quit noise when switching on and off the engine. This problem is probably due to the double-window that has been reinstalled 3 times with me. Now also this disc squeaks. My question: Does someone have this/s experience/problem and can someone tell me what was done with him/her to solve the problem? 2. Quiet Quitchen I can’t say much about this – I didn’t pay attention when the workshop master explained that to me. 3. Vibration of the car while giving gas, so a little more acceleration. So the problem is only when accelerating. Please help me!! So slowly I feel a little stupid, especially when I drive into the workshop the engine is buzzing without giving anything of itself X(. I hope someone has had the same experience and can get a If there is any interest, I will be happy to keep you informed! But please, who had a similar problem, report to you! THANK YOU!! David
