Excellent write up.... I never thought of working on my cars until I joined here and saw how many people work on their cars and save a bunch of $$$.
The first thing I paid for when I bought my Z4M was to remove the CVD. I paid $200 for that.... now I pretty much do all my work by reading and learning from all of you.... so every time I get under the car - I feel like punching my self for not trying to remove the CVD my self. I could've saved that money for the Mod-foundation
Thank you for sharing!!!!
