How did you notice the bolts were broken? Was there a check engine light? |

Yeah, Check Engine Light came up, I drove about 4 miles to work and then another 3 to the dealership with reduced power.

Lots of great info, thanks everyone! Just a note, the screws listed above are oil pan screws, so don't get your hopes up :P

Did anyone with early prod date N55 find a way to get this SIB work done as a preventive maintenance, or as a goodwill arrangement, even if the SIB situation below was not experienced?
SITUATION: A rattling noise can be heard from the engine compartment; the engine exhibits a loss of power; and the Service Engine Soon lamp is illuminated. One, or more of the following faults may be stored....

The dealer won't do anything as a precaution. They will only repair once the bolts have broken. That is why we have people interested in replacing the bolts as a preventative measure since it could potentially cause a lot of damage if the bolts do break.

from my experience I would take your car in with the SIB, it's a big deal that they should fix it and complain to them and how they operate. I payed $3700 two days ago for this crap, so frustrated but now it runs really well and smooth! I also learned that a downpipe with the n55 creates idle issues. |

Anyone stumble upon any pics of the valve cover removed on an actual N55 engine? It's hard to tell if we can get to the bolts from the pictures so far in this thread.

Ive ordered the transmission and engine magnetic drain bolt from http://www.drainplugmagnets.com/.
This is obviously not a cure, but cant hurt if the VANOS bolt heads ever pop, and fall in the oil pan, by pure luck. Since my N55 is in the dreaded production date range (May 2010), I will eventually be doing the Vanos bolt replacement fix as a DIY, maybe before the base warranty ends. Really hoping to see someone take the plunge soon, and document his DIY procedure.

Do this with the last 7 VIN digits againt REALOEM.COM ... Then, if you are in the hit list, use your best PR skills to convince your Service Advisor, or his manager to get this SIB implemented as a preventive maintenance. I dont think any members have succeeded, unless the issue has actually occurred under base warranty.
