Hey everyone, recently joined the forum with my L400 and asking for help.

My major problem at this stage is that I cant get the engine to spin up while in gear. When the car idles in P I can rev the engine to the redline no problem. But when when I shift into D or R the car seems to struggle in full throttle or after 2.000RPM Black smoke coming out and the engine starts to make clanking knocking sound.

Just so you see the problem I made a video a while back. Since then I didn't have chance to diagnose or work on the car.

Here it is.


If anyone knows whats wrong here please dont hesitate to share your thoughts. I have been messeged once on my FB on this matter with a brief explanation about a no name filter being installed in a blind rivited rocker box that gets contaminated and needs to be drilled out, but I am not even sure of where its located.
Thats as much as i know​
 
I didn't watch the whole video; is that the right one? Try disconnecting the exhaust... it could be a clogged catalytic converter.
