Thumbs down Beware: Widespread Vanos failures in E46 M3s

My vanos failed two weeks ago on my 2006 E46 M3 with about 29k miles, literally on my way home from the dealer after having the service II performed a second time (after I caught the dealer not performing the work in the first service II). Now BMW NA is refusing to cover it under warranty. I did some research and learned I am apparently one of many! I sold my 2003 E46 M3 after I got a notice from BMW NA saying they wanted to rebuild my motor bottom end due to faulty components - and as I recall it took BMW a few years of denying claims under warranty and blaming owners in order to avoid paying the warranty claims before they were shamed into admitting that they used defective parts in building E46 M3 motors. This appears to be a repeat of BMW NA's fraudulent and deceptive trade practices.

I am drafting my complaint now against BMW NA and the dealer for breach of warranty and fraudulent and deceptive trade practices. If anyone has had an E46 M3 vanos fail and you want to help me fight BMW NA, please PM me with your info and details.

I have yet to check other forums, but will post the threads if I find them.
