I'd still lean towards turbos, unfortunately. Low boost and slow spool could be a boost leak. Add in soot & white smoke and that means you're likely burning some oil. Then the rattle. All of that added together tells me there's a shot turbo.

Poor fuel economy and rough idle are common symptoms of leaking injectors. Could be as simple as spark plugs and/or ignition coils. Otherwise, the odd exhaust sounds seems like an exhaust leak somewhere. Loose ********* or fittings elsewhere.

All of these things popping up at the same time seems unlikely, but I'm struggling to think of any 1 single issue that would lead to all of your stated symptoms.
Really appreciate your reply mate. I'm going to purchase MHD app and upload some logs on here. I have no idea how to read logs so I might need a hand lol.

The car is running super rough!! Zero power!
