2011 N55 Vanos continued problems

Had Vanos bolts sheared and retrieved in oil pan at 56k miles, under warranty, just before the U.S. Recall.

Have had more than a couple of Check Engine Light, Reduced Power (CEL, RP) incidences. Dealer wanted $1500 for a Valetronic motor, that miraculously has been working fine without a replacement.

Now, at 74k, CEL,RP again, dealer wants $1500 to replace my chewed up timing gears and timing chain.

I've sent multiple emails and made multiple telephone calls to BMWNA, explaining that surely the sheared Vanos bolts chewed up the timing gears and timing chain on their precarious journey from the head, through the timing cover chambers, down into the oil pan.

BMWNA says sorry, your car is 24,000 miles out of warranty, it is not their problem.

Anyone else having timing gear and timing chain issues since their Vanos bolts sheared off?

Heading down to dealer to hopefully take a look at chewed up timing gears and timing chain on my N55. Will report back.
