C63S Edition 1 (2015) loss of boost, vibrating and acting up
So this is what happened, the car was absolutely fine for about two years, and one day I decided to do launch control, I didn’t know the car would shift up by itself so I shifted up milliseconds after it had already shifted up which resulted in limb mode. After that incident the car never drove the same, I used to step a little bit on gas and boost gauge will be at max. Now I have to floor it to get boost gauge to max. There’s a noticeable loss of power, vibration, the car always feels like it’s dragging behind, I remember before the incident if I stepped a bit on the gas it would give me acceleration on the same gear, now it downshifts immediately like I’m carrying an extra ton in the trunk. There is a whistling sound after I’ve accelerated and while rpm is going down from 4K to 3k like you see in the video. I also should note that I used to top up a liter of oil whenever the “add oil” message came up so I’m afraid that I may have overfilled oil and done some damage. I changed spark plugs today and nothing changed. Also I noticed some really sticky oil inside of turbo intake and didn’t know if that was normal. Any insight would be much appreciated.
