Alright, I have a 98 z28 a4 with no mods whatsoever. Yesterday, I went to change the oil, I used mobil 1 5w-30 performance blend. After it was all said and done i checked to make sure i had the right amount in, and i did. I cleaned my screen on the mass air flow sensor and cleaned out the intake. I
reinstalled the MAF and intake lid. I start the engine and the Service Engine Soon light comes on. I check and i have the proper oil level in my car. Pressure is normal and the MAF seems fine. What could i have done wrong. I need some help because I dont have access to any diagnostic machines. Please post your opinions.

go to autozone, tehy will pull the code for free. without knowing the code, its almost impossible to tell you what it could be.

If the car runs fine, get it deleted, sometimes mine throws a code and it's something stupid. Usually never shows up again after its deleted. Just my .02
