The Check Engine Light may illuminate with a knock sensor code stored. Our technicians tell us a revised knock sensor and bracket should be installed, along with heat shielding material to protect the new sensor, to correct this condition.

    I was told by the Audi technician during an oil change that they noticed a knock sensor problem that generated a check engine light that came on for a few days and then went out. I haven't had anything done for it yet. 2011 Q7 TDI
