How do I know if my NOx sensor is bad?
NOx Sensor Problems Most times, this will be immediately obvious due to the illumination of your ‘Engine Warning’ light in the dashboard cluster, along with symptoms such as unstable idle, juddering/jerking while driving, and excessive fuel consumption.
Where is the NOx sensor located?
The NOx sensor is part of the NOx reduction aftertreatment system used in diesel vehicles with urea based SCR systems. The sensor located upstream of the SCR catalyst directly measures the engine-out NOx gas concentration, which helps determine the optimum amount of urea injection.
Can you repair NOx sensors?
While the NOx sensor itself is a relatively complicated (and expensive to replace) unit, it’s often the case that the sensor is completely fine, but the probe used to test for NOx levels has malfunctioned. Many people are unaware that it’s possible to simply and inexpensively replace the probe with a little bit of DIY.
Can you drive with a faulty NOx sensor?
A bad knock sensor may also not let the engine accelerate properly while driving on the highway, and cause the vehicle to lose fuel mileage. Once the computer realizes the knock sensor is not working properly, your vehicle will most likely lose power.
Can you drive with a bad NOx sensor?
In conclusion, you can drive with a bad knock sensor—that is, if you want to destroy your engine and get atrocious performance from your car. The moment you confirm that your knock sensor has seen better days, it would be wise to swap it right away with a high-quality replacement.

Can I drive with a faulty NOx sensor?
Is it OK to drive with a faulty NOx sensor?
How much does it cost to replace a NOx sensor?
If you have a standard economy vehicle, you can expect to pay anywhere from $120 to $500 for replacing your knock sensor. The parts cost will be anywhere from $65 to $200, while the labor costs will be anywhere from $50 to $350.
What happens if NOx sensor fails?
What happens when the NOx sensor fails? If a NOx sensor fails, the vehicle can have multiple faults on the dashboard which will put your car into limp mode. NOx sensors are directly linked to the SCR system. There will also be emission and general SCR system faults.
What causes a NOx sensor to go bad?
NOx sensors monitor the level of nitrogen oxide being emitted by a diesel vehicle to ensure compliance with emissions regulations. Common causes of failure include soot buildup on the sensor, ECU water intrusion, and/or damage to the cable, which will cause the check engine light to illuminate.
Is the NoX sensor on my club Touareg full?
About 1.5 qts was from the last jug, which sat all winter in the unheated garage, the rest was from a fresh jug recently purchased. Never had this issue before with leftover adblue. I cleared codes again, but the adblue warning is still on indicating 450 miles left until tank is empty. Re-checked tank and it is full.
Why is my NoX sensor not working on my car?
The manual says my sensor message and mileage ’til no start is caused by poor reductant quality or something like that. I have your error codes minus the Adblue issue. It sounds like a lot of problems come from the emissions system. I’m halfway tempted to delete all of it.
What’s the problem with my club Touareg AdBlue tank?
Not sure what is going on with adblue quality. Oil was changed by me last Monday and the adblue tank was filled. About 1.5 qts was from the last jug, which sat all winter in the unheated garage, the rest was from a fresh jug recently purchased. Never had this issue before with leftover adblue.
