Newbie here needing help

[Reded]

Hi all picked a x5 3.0d e53 up last week with a few issues first had black smoke on acceleration so I changed air filter and cam breather and then found a vacume hose not connected the smoke is a lot better but there is still some smoke still then I changed oil and filter because it was leaking from top of the filter no gasket fitted and now I have a oil leak on passenger side of car so changed pressure switch too but still a leak any help with these issues would be great

If you got a leak since changing the oil filter... that would be the 1st place to check...

re black exhaust smoke.... being a diesel machine... blavk smoke isnt unusual on hard acceleration...
also bear in mind... maybe the previous owner drove like they were chauffeuring their mother-in-law, in which case the CAT converter could be coked up & your little pedal pushes are simply clearing the throat of the thing.


a good oil & filter & air filter change will not go amiss... as these machines like a 10k oil change... use the right oil though... not some cheap crap..

Just a update car came up with heater plug fault would this cause black smoke and if so would it be the module or the plugs ?

Heater plugs only operate within the first few seconds of a cold start and then shut off.

Replaced the vacume pipe from the black box on drivers side that goes under the inlet manifold
