Car is throwing a P2135 error code. Mods are in sig. Is there anything I can do to resolve (disconnect battery, reflash, etc...) or should I just re-tune to stock and put the old intake on and take it to the dealer?
Yeah. I guess I have to put the stock air box back on and flash it to stock. I am concerned about the dealer updating the tune. I have heard this can cause problems when you try to reflash the preformance tune.
Basically, read your strategy with the tuner before you take the car in. Write it down. When you get the car back, before you try to reload your tune, read the strategy again, and make sure it didn't change.
