Hey Guys,

i am getting these two codes both running rich bank1 and bank2. also im feeling a hesitation/cutting out under full throttle. When nice and warm the car feels sluggish and a bit of a rough idle it doesn't respond to throttle like it should. Could this be MAF? injectors? vacuum leak? not sure where to begin...i started focusing onto vacuum leak but in reality not sure where to look. i checked DV's hoses and they seem to be okay and checked via carb cleaner method and idle didn't change the slightest. I'm simply out of ideas now and looking for any and all help from people who found or came across same symptoms. I'm pretty sure i missed a few things here and there so if you have a question to help you narrow it down please let me know and ill try to answer the best i can

thank you in advance

Check the above items if you have a vag-com or vcds.

Notice: e.g. faulty O2 sensor/s do not activate check engine MIL lamp.

Thank you,

I as well came across this article and have it saved in case. I'm debating doing it myself or just taking it to a dealer and having it corrected in one shot :s still debating

Good morning

I smelt a strong gas smell this morning....could this be on any way related? If so what should I be looking for?
