Glowplug, glowplug module, injector or egr valve?
Discussion
Slightly rough idle at cold start up for a few seconds with a slightly slower start than usual used to be 1 crank but it is nearer 2 now.
Under full throttle onto a slip road when half warm there is a metallic rattle that is very fast in terms of speed obviously until???? I let off, this noise is only these under load not at any other time. When up to normal temperature it sounds just as smooth as usual for a 6 pot diesel even under full throttle.
Mpg is probably about 0.5? to 1 mpg down around 34.
No white/grey smoke from the exhaust but it has done a regeneration twice this tank instead of the usual once.
Head is saying diesel injector or glowplug, but it is booked in for diag with bmw end of Jan. But just want ideas.
I have extended warranty so not that worried regarding costs honestly...
M?ile?age is 44k.
Have already had my egr cooler replaced in September
before it gets mentioned
Car is a 640D...n57 engine.
