This is what I’m hoping. I would need to check, but I would think that as long as the flaps are not stuck in the closed position or any variance of, then the map could be a solution.At the price that @A2Steve is indicating, it could well be a cost effective alternative to a manifold refurb, and N316 replacement, particularly on high mileage engines. The exchange facility would mean down time could be very short too. Certainly worthy of serious consideration.
Have to amend the tailgate moniker though, to FI!
