Default Error P0171 on Mk2 - Replacing MAS Sensor

Hello Guys!
I got Error P0171 - Powertrain - System too Lean (Bank 1) on my Audi TT 2008 Mk2 2.0L
What is the most common cause of this error?
I would try to clean or replace the MAS Sensor to see if that’s the cause.
I’m not an expert at all in car repairs but I should be able to manage the repair myself to save some bucks.
I’m finding just tutorials on Mk1.
Can some kind soul point me in the right direction with a picture where the MAS is located?
Any chance there is a guide for the Mk2?

Many thanks!
Fede
