Default Audi TTS MAF Sensor Problem

Hey guys I had a question, I just got this TTS from an auction and I’ve done all the maintenance on it. The MAF sensor is what is causing me trouble, the car dies at the lower rpm’s when plugged but when it is not plugged it runs totally fine. I have already changed the MAF sensor with a brand new one and it still does the same thing, I’ve also checked the fuse on the left side of the driver dash and it’s good. I am totally lost, when I plug it in turns off and dies which makes no sense if it is brand new. Also to mention it has an aftermarket intake so idk if that’s what causing it to maybe stutter. Any help would be great thanks!

Have you plugged in a code reader to check for any error codes?

Yea I was getting back the code P0100 Mass or volume air flow sensor "A" Circuit. Still makes no sense since I just changed the sensor.

This article is worth a read. https://www.obd-codes.com/p0100

Since the MAF is new, have you checked the connector and/or wires for any corrosion or damage?

If you have OBDeleven, you can check MAF functionality -
  • Control Unit 01-Engine
  • Live Data
  • Channel 003
