Ok...I have a 1999 audi a4 2.8 auto awd. 178,000 miles. Got this car for 17 yr old son as his first car. Bought the car for 1600 I figured if a put a few bucks into it it would be a good first car for him. After a few months we are getting some codes. Mass air flow needs to be replaced and we are doing the vacuum lines too...that's ok. But now these other codes are popping up. Any idea's or info would be great...just have to put this out there, I am a Mom doing this with him, so go easy on me please. TY in advance.
I got these codes:
