Hi all!

So, a few weeks ago I started noticing what would be a strong exhaust fumes smell in the cabin. At the same time I also noticed some judder/shaking while accelerating in 7th and 8th gear. But only when accelerating and low rpm (around 1500-1600 rpm). No issues in lower gears and idle. Keep in mind, all the happened on the same day. No symptoms before. Took the car to the garage and it turns out the culprit was a leaking injector. The changed the o-ring and the seals in that particular injector. I got the car back, no smell of the exhaust fumes in the cabin so I thought that issue is solved. Surprise, surprise... Juddering/shaking still there. Im no mechanic and know very little about this and I also went through some other threads. Some are mentioning drive shaft, faulty injectors and so on.. Someone had a similar issue?

Thank you!
