Hi, i have a 2004 RS6 that is suffering from hesitation in acceleration around 2400rpm. Ive checked the forums for MAF sensor, Torque converter and oxygen sensor failure but none of the symptoms seem to fit. The garage have a computer download to indicate the replacement of the oxygen sensors with the Check engine light code.
Please can you take a look at this link of the symptoms and see what you guys think is wrong?
The garage want 12 hours labor to do the oxygen sensors which is clearly madness, i have read three hours to replace all four is about right?
Really appreciate your help in this matter as i have a feeling that its not just the O2 sensor that is causing this.
