Default STFA: can bad o2's trigger limp mode?
After searching I'm still not clear on the answer: can 2 failing B1 o2's put the car into limp mode?

Default 17963 - Charge Pressure: Maximum Limit Exceeded = Boost Leak, Check the Y fitting in the wastegate..
check the plastic Y fitting in the wastegate hoses at the back of the engine. It could be cracked and leaking air under boost but not look bad unless you pull on it.
