V50 2.0D 136

Long story short, I had fault logged that pointed to Fuel pressure regulator, and after trial and error on the ordering side, I got the correct part delivered today and fitted.
The error code vanished after fitting, but the smoke persisted.
New error popped up.. Air Intake Temp sensor appeared to be the culprit, so a 80 min round trip to Euro car parts later and new part fitted, but smoke still persists and so does error code.
Another trip to Euro car parts and MAF collected, but issue still persists.

Old AIT sensor was smothered in oil so it would have needed removing, and throttle body was much dirtier than expected, but as I wasn't planning to remove this part I didn't have any cleaning products available, so this is a job for Monday.

Car is smoking (black/greyish) badly and economy is awful (300 miles to a tank if I dare to drive it).

Any suggestions on where to look for problems? Today has been expensive and stressful, and I'm no closer to finding the issue.
