Thanks RobinA3 went ahead and replaced the sensor then borrowed a friend's laptop with VCDS to adapt the sensor. Cleared the codes after and ran another scan and the issue looks to be fixed now.
Thanks again for your help :)
An engine light has flashed up on my dash and using the code scanner I have, it comes up with a single P0471 code "Exhaust Pressure Sensor A Circuit Range/Performance".
Looking up similar codes online for other VAG group cars, I have located what I believe to be the exhaust pressure...
