Bruce - my new battery was installed by my mechanic who specializes in imports.
I have ordered a new MAF sensor that I can install myself and I am hoping that will cease the P0171 code I am getting.
As far as the P0300, P0301, and P0302 I will have the mechanic check the ground and test the alternator.
As far as getting my ECU reset I am hearing conflicting things from lots of my friends and on the internet. So, when replacing a battery for an Audi or other German import does the car have to go back to the dealership to have the idle codes and other info reprogrammed?
Thanks again for your prompt responses as I am learning quite a bit about my A4.
