Secondary Air Injection System Switching Valve Bank 2 - P2242 Stuck Open

[bluestyle55]

Has anyone dealt with the following fault code:

Secondary Air Injection System Switching Valve Bank 2
P2442 00 [237] - Stuck Open

I am stage 2 APR DP with stock exhaust. Car is running strong but keeps throughing this code every few days.

Trying to avoid a huge diagnosis cost from Audi. Any comments appreciated!

sounds like you might need to replace/clean the solenoid valve at the back of the engine. I have no idea what the process is like but as someone suffering from constant P0491 codes I have been doing a good amount of research into the whole SAI system.




Shouldn't affect performance at all but if the valve is stuck open you might be getting some exhaust being blown through the system, which may cause problems later on, especially when the air pump is on but exhaust is being blown back.
