Got a 2010 330D, starts first time but was a bit lumpy.. has recently got a lot more lumpy, sometimes lumping itself into a stall. Had all the glow plugs replaced yesterday and kept fingers X’d it would sort it.. but it hasn’t. (They were due for a change anyway I suppose)
Still very lumpy/shaky this morning but as always is fine by the time I have driven 3 or so miles and is then seemingly stable. No engine light, no faults in dash.
Had diags done a while back. Pic below.. some glow plug stuff in there and ‘swirl flap plausibility’ etc.
Torn now between fuel filter, injectors and glow plug control unit. Does anyone have some input on the potential issue? Here is a quick YT of what it sounds like..
