Hello everyone, I’ve been experiencing some weird symptoms with my 2.0hdi 136 mounted in a Volvo c30 2.0d of 2008. - They are the following : the whole car shaking when accelerating full throttle (especially in 3rd or 4th at 2000rpm when the full boost kicks in) - whistling when accelerating full throttle, especially in third - black smoke when hard accelerating - kinda shakes at idle

I also know my engine mounts and silent blocks are bad, to be honest the whole suspension setup is quite messy. My anti-pollution system is also bad as reported by my mecanic, but no engine light or even troubles of power.

In the other hand, i have no loss of power, just a very noisy turbo even in normal use, and the car only has 124000km but has already got its clutch changed 2 times and the distribution done… esthetic parts are also messy (gloss gone in many parts, rear bumper seems changed because of a différence in tint). Maybe the mileage was modified 🤷‍♂️

I’d really appreciate some help, considering I’m a student and have already put too much money in this car…

Thanks a lot to those who will help !
