    RE: Quick e46 question

    Is that an aircon pipe? The steel one out of the rubber? Could it be dried in aircon gas?

    Or else your car does coke through the grilles!!!

    Quick e46 question

    Is that a mark of a pipe wearing off your manifold or did you rub it with your finger, hard to tell from pics.

    Are your washer jets leaking by any chance? Additives in the washer fluid go dry out white like that.

    Thats a mark from the bottom plate (the heavy bit) of the cabin filter housing no leaks on jets that I could see john

    Cabin filter was soaked that I removed last month and replaced I re-aligned all seals new one is still bone dry not sure if its related or not but theres no white powder in the cabin filter housing itself

    In that case maybe the rubbing is causing plastic dust... ?

    Quick e46 question

    Gar, it's rubbing off the underside of the pollen filter housing. Caused by the cover not being located properly in the little spuds that locates it in the intake manifold. See it all the time
