GLC 2017 model year Nox defective, where is the cable route?
Hello everyone,
The check engine light is on on my 2017 GLC. I read the error codes and found the NOx sensor was defective.
Now my question. My vehicle was at Carglass in January. They replaced the windshield. Unfortunately, the window on the passenger side wasn't sealed. Whenever it rained, the floor (on the passenger side) got really wet. I suddenly noticed that the window wasn't properly sealed.
I know that all the cables are routed directly under the floorboards (passenger side). My car is now back at Carglass. The car has to stay in a heated garage for five days.
Since most likely all the cables under the floor are damp, I would also like to know if the NOX sensor cable is also located there.
Could the humidity be the fault of my NOX sensor?
Can someone please answer this question for me?

In this year of construction and model, it is normal that the Nox sensors are broken. This is probably not related to the water collapse.
Let a new original Nox sensor be installed. It’s almost always up to Mercedes. Retrofit sensors do not last long.
Hello Christophror, now all my assistance systems ( Parkpilot, Distronic, Active high-beam assistance, lane maintenance assistant) have also failed.
Of course that’s different. Let the car read at Mercedes. If there’s any mistake in Can Bus, it might have to do with your water break.
There’s a tie right under the driver’s seat. That was the problem. Alsi because of water
And now there are other mistakes. “Without a change of gear” Next week I have appointments with Mercedes Service. I slowly turn through:@
Hello!
I also have a GLC of 2017. My windshield was also wrong from the factory. With me, luckily, no water went in, but I had an extremely acute whistling sound from a speed of 170kmh, so you couldn’t talk anymore. Mercedes has changed from cunning but after eternal discussions even until the management. (conversion with the customer under all sauce)
The NOX sensor is also now defective and the engine lights. Mercedes does not take over the costs for the sensor, my car is already 5 years old and my guarantee about which this could have been regulated expired 9 days ago. Cost of €500
The sensor measures the nitrogen oxide content in the exhaust gas and supplies this data to the engine control device. Quite unlikely that the water causes disturbances here. The cables themselves do not itch when they are in water. Highest plug connection…
You’ll need a new sensor…
Error found. Water damage. Several control units damaged. Unfortunately damage in height cirka 20,000 euros. Let’s see how Carglass reacts to the cost proposal tomorrow.
