Fault Code P220A Engine light

[Day_Walker]

Hi everyone,

Just bought an A6 Avant Sline Black Edition 3.0 TDI SA 66 plate and I'm in love with it however I've only owned it just over a week and the engine management light has come on. I've not noticed anything broken or feeling wrong with the car but I bought a Carista ODB2 and it returned 41 errors! Top error was P220A. I've had a Google around and there's not too much information about this error with Audi's but I believe it's to do with the Manifold Absolute Pressure/Barometric Pressure Circuit High Input which can just be a dirty or faulty sensor from what I can gather. 

I'm tempted to just clear down all the errors as some of them may have been fixed and not cleared and if it's a real problem then the engine management light should return quickly. 

Wondering if anyone's had anything similar? 

Thanks in advance.
