Hello together I have a problem again with my Renault Scenic 2005 diesel engine. After I was on the road last night everything was still running completely normal. Then I parked briefly, was short at the bakery, wanted to get back in, switched on car and I had a quite loud knocking noise in the engine room.In the afternoon I was at my workshop to have it checked, what suddenly happened with my car. After the car mechanic then the car control he said to me that it was hydraulic plungers. So he threw some oil in it, even though the car actually had enough in it (was about minimum). A few weeks ago I had already filled oil myself, because the car had shown this on. Of course also the right thing! He then told me to drive around with it for a few days, 2-3 days, and see if the noise disappeared. But now I noticed something today. e knocking is partly gone, but I have another problem and that’s how it is when I give gas that the car is extremely loud. I also have the feeling that the car comes much slower to the speed from normal and according to my inside indicator I had today several times just on 13 l/100km, which is not the case otherwise! It sounds like the exhaust is over, however the noise definitely comes from the engine compartment (which I think at least!) If the car mechanic but most likely even if there were something with the exhaust or pipe or not? The sounds can only be heard so extremely loud when you are sitting in the car. If you are standing in front of the bonnet, it is not much louder than usual. Besides, I hear a very easy rattle from the front. What I find strange is, if I brake the car or kick the clutch, the car is so extremely quiet. Yesterday at the car workshop I also noticed, that the engine has wobbled quite a bit when starting, whether this is normal or not, can I not judge????????? Maybe you can help me. I am overwhelmed. My car is like an Advent calendar, constantly finds new ?? Thanks already and sunny days still. Lg
