Mein Auto: 335i
Intake Camshaft Vanos Adjuster Case Bolts Sheared

335i 2011 with 37700 miles. No problems. Hesitation followed by "Engine Malfunction" warning light. Drove another 15 miles or so prior to BMW Service Center. Found shearing of intake camshaft vanos adjuster case bolts. Pieces in timing chain guide, oil pan, stuck between timing chain and guide block. Dealer replaced vanos units. Checked compression and leak down test, which supposedly okay. Good as new, right? Have 12,000 miles on factory warranty, right? My question is: Who knows what damage the metal pieces did to other components en route to their final resting place in the oil pan, i.e., cam chains, gears, sensors, crankshaft, oil pump, oil galleries, etc.? The long term reliability and integrity of the engine has been compromised, right? What could be remedy other than engine replacement?

Pieces in oil pan not hurting anything. My only concern would be if a chunk followed the chain over a gear or a guide. Then a gear tooth could chip or a guide crack. If no unusual noises being heard you should be ok, but the case is documented if something becomes apparent. I wouldn't be too concerned.
