330d smokes when on a long journey
Discussion
Right going to try again and see if anyone can shed some light on my smoke issue ....my 330d smokes when i go on a long journey ie when im doing say 60 for a while it will start to smoke take my foot off and sometimes it will clear and sometimes not have been told it could be turbo but it doesnt smoke when im just driving around locally and the car still goes like stink and i can hear the turbo whistle ..also have been told it could be the seals but surely if that was the case wouldnt it smoke all the time ....any help to sort this would be grateful as i cant go any distance in it and thinking of getting rid thx....😡😠

I missed any previous discussion on this, so could you clarify the colour of the smoke, is it blue, white or black? Thick clouds or more like steam?
I wonder if it's worn injectors or something like that?
Possibly not if the smoke only happens when he takes his foot off the accelerator. I wonder if it's worn injectors or something like that?
OP more info needed. Colour of smoke, age and mileage of car, etc.
Likewise I think we need more info about the engine but I take it from the 330d description that it's a diesel. It could be regenerating the DPF (Diesel Particulate Filter)
It only happens on a long journey and can be stopped by easing off the throttle which will cut the fuel and reduce the temperature of the exhaust. I don't understand why it happens on every long journey.

Hi sorry for not replying the smoke seems to be a grey colour i have replaced the ccv for the vortex type cleaned out the egr i can drive it around all day locally without smoking ...i know when its about to smoke as i smell like a burning oily smell could be a diesel smell... its a 2000 e46 330d se auto if this helps 179000 miles ....run inpa and have a code 13573 which is glow plug or relay wouldnt of thought this would cause the problem as i thought the glowplugs were just used to start from cold...? no dpf on my year...
Vortex filters can make these early M57s smoke more. The best filter is a standard BMW loo roll type. Is the air filter new? You can check injector leak off too. Glow plug faults won't cause any extra smoke. Excess smoke (grey/black) on these can also be caused by holes in intake/turbo pipes and also by soft pipes and a leaking intercooler.
An air mass test is also a good diagnostic aid, this compares actual air mass against desired at various set points. Grey, oily smoke can also be a sign of turbo failure.
