hey guys,
i just got my first p0300 today after almost 20k Xede driven miles. i also noticed a stored code of P2263 Turbo/Super Charger Boost System Performance. that one isn't very old since i just got inspected 3 weeks ago. the p2263 didn't pop the SES light. could the stock boost solenoid be to blame for the P2263? help is appreciated.

thanks
vincent

ps i'm running a gt3076r.

 

search ebay for "CReader OBDII". Buy the one that isn't for VW/Audi's and voila, best $40 ever spent. Leave it plugged in, no more CEL to worry about.

 

Hope this helps,
