just got my car back (2011 bmw 328i n51) from Bmw of el cajon. I brought it in for recall and diagnostic. Code is 2A7C and I have been trying to fix it. I started replacing aftermarket VC for PCV problem, aftermarket Vanos solenoid, intake cam sensor. IWhen I brought it in, I mention to Laralyn(SA) about the Sulev Warranty and she told me that she will help me out. The problem was Vanos units. intake vanos 3 bolts damage and fell into oil pan. exhaust vanos bolts loose. They replaced Vanos units under Sulev warranty and was asked to put new VC(OEM) or cleaned the silicone that I put on the aftermarket VC. For the price that was quoted on cleaning, I decided to install a new VC. Car runs great so far.
