leaking vanos accumulator
before buying a 02 M3 I had a top to bottom inspection performed. One item noted on the report was that the vanos accumulator was leaking and recommended a replacement (app $500+). after I asked if this was an urgent matter I was told ..NO it is not. I'm wondering if this is something within the skill set of an average skilled auto mechanic that I could do during the winter months that are about to set upon me? Comments?
