Audi A6 NOx Sensors
Hi all,
Does anyone know if the Audi C7 TDI has both upstream and downstream NOx sensors?
I’ve been having some AdBlue issues the last few weeks and getting 0 readings for the ‘NOx sensor after SCR cat con’
The ‘NOx sensor after SCR catalytic converter’ voltage is also showing 0 volts
Before confirming a dead sensor could anyone confirm if there are indeed two separate sensors in this model.
Thank you!
