just wondering if changing the intake vanos solenoid is the fix
Yes BMW has a bulletin for this issue. One need to check to make sure the center part of the oil filter cap in still present this sometimes gets pulled out during the filter change and thrown away unknowingly. If thats there then I would change both solenoids and do a hot oil change. This will normally take care of the issue. Of course it the fault keeps returning you will need to look into worn cam bearing ledges or possible vanos unit issues (seldom it gets this bad though)
thanks, your talking about the black cap that screws on filter housing ? I'm not sure what you mean by center part, I have been changing my own oil for 15 years and am not sure what it is your talking about. And if the center part is missing where do I get that or do I need to order a whole new cap ?
Yes it is under the black cap. When you remove the oil filter the part that the filter slips around would be missing.
no not the case I've been changing oil on my bmw's for 15 years, I know all was there when I reinstalled the cover.
I assume your talking about the stem where you put the small o-ring on, I know I changed that o-ring so it was there.
Yep that is correct then it most likely is the vanos solenoids
