I had my 2001 s3 in for a service at star performance & one of the advisory notes was that the exhaust gas temp sensor was faulty.i never queried it as the garage owner was not there.i have since had a look around the car & there are two sensors.what issues would the car have if one of these sensors was faulty?there is no warning light on the dash & i am not noticing any real drop in performance.
is this something that would only be picked up checking for fault codes?lastly which one of the two sensors is it likley to be at fault?
thanks
