Little update.. I have another thread going on but it's dead so adding here.
The MPG and AdBlue usage got worse and worse, to the point we were getting around 10 mpg around town and 14 highway not pulling anything. Then, just after Christmas the check engine light came on P229F "nox sensor". The dealership was busy so they said bring it in really quick and we'll do the new software update, that should fix it. This did not fix anything and back in it went. This was mid-Jan.
2 weeks later, we had our car back with a new NOX Sensor. Drove it about 3 hours and the lights back, P229F again, back in she goes.. The car has been since sitting at the dealer while they do all sorts of tests and bologna trying to fix the issue. Some "specialist" from VWOA even flew out and couldn't figure it out. They examined all the wires figuring a rodent chewed something and no. Today we were notified the sensor on the DPF is getting replaced to "See what happens". Luckily we have a 2020 Tiguan to drive which is nice. Tomorrow I will be calling VWOA to involve them and hopefully push for a buyback or lemon law. This experience is asinine and not what I would expect from VW. I have now made 3 car payments on a car I haven't driven and they aren't getting ANYWHERE!!!
Anyone have any tips??
