NOx & Lambda sensors cleaning. NOx repair 

You can see the injector cleaner fluid is also in plastic. 😆

What is car model

Hello. I have audi a4 cnha engine, 2015 model. My vehicle is at 240,220 km. I took it to my mechanic for heavy maintenance and it has exactly the same set-up as your engine. I am very happy to see this video. I deposited the sensors in isopropyl alcohol while I was being serviced. The ends were left in isopropyl alcohol for 1 day. (2 exhaust gas temperature, 1 oxygen, 1 nox sensor). When I looked at the sensors, they were all cleaned, no residue, soot or dirt remained 👍. everything of the vehicle was ok, we went for a test drive and it turned on the check engine lamp on the road. when we got back at service, we connected it to ODIS and got the p2200 and p2209 errors. The computer directly told us that "the G295 and J583 sensor should be replaced, suspecting it to be defective." First of all, we checked to see if there was a problem in the wiring of the sensor to the ECU in terms of safety. Electricity was going to the ECU. So there is no problem with the socket. the problem itself was directly the nox sensor and control unit... (G295 and J583) I will ask if the cleaning process may have spoiled it, but I dont think that 99.9% isopropyl alcohol will spoil it, after all alcohol is a volatile and cleaning substance. Cleaning didn't work for me. should i buy a new sensor? exactly the same, including our sensor codes (8K0 907 807 J). And also I want to contact you if possible. I would like to send photos from instagram dm

Hello! I have an Audi A4 B9 150CP DEUA motor. Do you have any idea if is it possible to get a nox sensor from a 3.0 engine (Audi A4 B9 3.0)? Is it compatible from engine 3.0? Thnaks, Benjamin

Did you just replace the sensor or did you also replace the module?
