Hi all, I am new to the site. i have owned Audi TT quattro for only one week. Car has been running great, till now... Last night i was driving home and i realised i had no power/boost at all. It then started misfiring when idling so i have plugged in code reader for error codes...

16684
16687
17704

seeing these codes i checked cylinder 3.. when car was idling i removed coil 3 and it stayed the same.. i have ordered a new coil.

I have also ordered a new temp control sensor.

Has anyone had these same 3 codes with this problem.

any advise appreciated...


I will post in newbie section when i get a chance


thanks guys
