Dirt in engine compartment
hi gals and guys
my friends right side of engine bay is covered in greasy kind of powder (see attached pictures). he has been to bmw but they told him it may be EGR but not sure, basic so they guess. it does come off but where would it be coming from? thanks for your help |
