Are valvetronis and vanos part of the cylinder head?
I'm curious if I can just replace the valvetronic and vanos units or if the whole cylinder head must be replaced to be able to change the valvetronic/vanos.
And what are the parts cost like without the labor? realoem does not list the parts separately. They only list the price of the cylinder head with the valvetronic and vanos.
My engine is a N52, 6 cylinder NA engine.
