My X5 is a late 2011 LCI model.

Yes my E90 is a 330d with the M57n2 engine so almost any parts I need I can just grab them off my E90 including that throttle body. I heard that the throttle body is required for regeneration and if I recall correctly my soot was mid 40's and the glow plugs and coolant temp was fine but throttle body fault was stored which I why I reckon the soor has accumulated.
The car was fully serviced today and will have some new tyres and an alignment done tomorrow. Only then can I put it on the motorway to try and get a regen, if not I'll have to request one as I believe mid 40's is quite high.
