Yellow Engine Management Light

[andydin68]

Hi folks,

The yellow engine management light came on yesterday and is on again today. A quick scan of the owner's manual says its a fault with the engine emission system. Is this likely to be something as simple as an oxygen sensor or something more (expensive)

Car is a 2016 A6 Allroad with approx. 46000 miles on the clock

You will need to get it scanned and find the fault code, this will point to what the issue maybe but will need investigation and confirmation.
