I recently changed my MAF with a new one bc my maf was completely dead. I was only getting one code for about 1 month of driving and that was p0102 maf signal too low. Replaced maf car ran much better and no CEL. Was driving it for about 2 days with no CEL light. Driving it today and 2 CEL lights came on. p0343 Camshaft Position Sensor (G40): Signal too High, and p0411 Secondary Air Injection System: Incorrect Flow Detected. My question is can the wrong MAF in the car cause these codes. I bought a MAF but I'm not positive if it's the correct one for my car. I bought the same MAF code as the one that was in my car but not positive if its the correct one.. The MAF code is 0280 218 100. The car runs fine with this maf in. The only reason I'm confused about this is b/c I never got these codes before when my MAF was bad. Car is 2001 1.8t A4 with AWM engine. Thanks
