Any known solutions to codes P0174, P1075, P1077. If not what are some common related issues to said codes? There's not a certain time it comes on. Ill clear the code and maybe a day later it will come back, sometimes its back after a week. The car is not in limp mode or anything of that nature. I was wondering if it could be MAF related. I don't want to keep driving it with a lean code. Any advice or suggestions is appreciated.

If you suspect it's MAF related swap them and see if the moves to the other bank. otherwise a lean condition is too much air/not enough fuel....check for air leaks, vacuum lines, clogged injectors, restrictions in the fuel lines and also change the fuel filter.

VCDS - engine electronics - measuring values - 32(mixture adaptation)...what does that say when the light pops on?

It was the throttle body gasket. Thank you!

This may be a problem with the high pressure fuel pumps that are located on top of the engine. It will get worst with time and the car will start going into limp mode on acceleration. Both pumps must be replaced as the fuel pressure must be equal in both cylinder banks. The part # is 07L 127 026 A. Here is the ETKA diagram. It's #1 fuel pump; fuel rail; injection valve - Audi A6/S6 quattro(A6Q) [USA 2007 year]
