  1. I had my tires and sensors (to Hufs) replaced a few months back, everything was good until about a months ago (tire pressure has been fine the whole time). I had to rescan as it stopped reporting air pressure, then it would randomly work again, sometimes I would need an additional scan to work. Finally it's popped up with a have you changed your tyres question, I didn't think anything on it until it happened again. So far it's happened 4 times and the only way to get it to go away even if it's reporting the pressure is to have the sensor scanned again. Stopped by the shop they scan
  2. Follow up, it was a bad MAF. Got the part in today, replaced it with the same (looks like a v2) Bosch part number, and the car is happy again.
  3. Checked and cleaned it anyway (as it's just about new), still same issues.
  4. I got MAF cleaner, cleaned it (MAF looked almost new before cleaning), let it dry and cleared the codes. Started up the car and waited for the codes, normally the CEL would flash right away so I took the car out for a drive and after about 3 miles got the same CEL codes again. Took some logs and voltage isn't changing on the MAF 1.0107 volts (had to give it gas to get it to idle). 2020_04_17_19_06_20.xls
  5. I'm having a CEL with my car (997.1), I just picked up a Durametric and got 2 codes off it P1096 and P1097 Mass air flow ahead of throttle valve - implausible Car will not idle with the MAF plugged in (without pedal assistance), and unplugged it idles fine. Durametric shows voltage before start is 1.01-1.02 when started the voltage doesn't change. What else can I do to prove it's a non functional MAF or do I just need to go out and order a new one (any recommended brand and place to order from)? This might be related but I doubt it, about 1000 miles ago i
