Getting this recall and the airbag done as I type this. Tech estimated a little over an hour. He also noticed my valve cover gasket was leaking, and they're replacing it for free since I have the N51 and that's covered (along with other engine related components) under the SULEV 15 yr/150k mileage warranty. Another benefit of the N51
Also, the SA here tells me about 90% of parts that cause a check engine light will be covered by this SULEV warranty. Tried to get a print out but he says they don't have one. However, he says 02 sensors, crank shaft sensors, fuel pump, etc. are all covered. I feel like this should increase the value of the N51 equipped cars!
