Just making sure on something here. I have a 2002 passat 1.8T AWM and 145k miles with trouble code P0102. It all started one day last week when I started the car on a cold morning, lots of odd noises could be heard. It almost sounded like the SAIP was failing. The check engine light came on. I hooked up the vag com last night and verified the code again. I also checked the airflow and it showed 0 g/s at idle and same while driving around. Is it normal for a MAF sensor to fail completely? A lot of the search results seem to show the MAF sensor still reading something, even if not much. I pulled the MAF sensor and nothing obvious shows up. I have cleaned it a couple of times in the past, so maybe it's just time to replace it. I guess what I'm asking is if it could be something else. Just making sure before I buy a new one without ruling other things out first. I'm using the limited version of VCDS-lite, so I cannot check fuel trim, MAP, or other things.
Thank you.
Thank you.
