    I am trying to solve for secondary air flow insufficient on both banks. I believe the issue is with the vacuum lines to both secondary air valves and they are not opening to allow the air to pump into the exhaust from the pump. I can't find any leaks in the vacuum lines. The lines come off an Accumulator box that has a solenoid. I believe the solenoid acts as a switch and for some reason may not be letting the air go through to actuate the secondary valves. If you look below you will see the solenoid is part# 53. It's coming off a vacuum accumulator box (#19). Visibly the box looks fine, but I dont know how long these things last. Any help or advice greatly appreciated.

    just had this problem on my 14 FF. I do not work on my cars. I can't live with the check engine light so I brought it in for service to main dealer. I hope you can rectify the issue on your own bc it cost me about $4,000! Frustrating since the car runs perfectly fine with those codes. I think I have the same codes being thrown off on my 575M and just leave it alone cars runs great!

    Thanks for the insight. Do you mind looking at your invoice by chance and summarizing how they fixed it? Curious what the issue was and why it was so pricey
