Hi, Thanks for Video. Which app do you use for reading/clearing code? Also what is the OBDII device ? Thanks again

[@diyprojects-rd6431]

Hi I use the Autel wireless obd II tool. This fits in a socket under the steering, in the footwell

HI , MIGHT SOUND A BIT WEIRD BUT WHEN YOUI CLEAN AD BLUE DOES IT NEED TO EMPTY ADD BLUE TANK AS IVE JUST FILLED UP AND CODE SHOWS UP VERY NEXT DAY ..THANKS

[@diyprojects-rd6431]

I did not have to empty the tank. I suggest checking the sensor. That may need cleaning/ or changing.

Hello, nice video, I have code P20F5, I cleaned injector but code after deleting still appears. Should I remove nox sensor? And clean in as well? Which one should I remove because there is a two nox sensors? Same as on your video

[@diyprojects-rd6431]

Yes the nox sensor gets clogged ( did not in my case) - best to check and clean.

[@t7ank]

Did you change for any new parts or just clean? Did you have P229F error?

[@diyprojects-rd6431]

The video explains it.

[@Idevendrasen]

I have same codes coming up. Did this cleaning resolve your issue?

[@diyprojects-rd6431]

Yes

[@user-rv8wh8lu5g]

Did you have problem with nox sensor going out all time that is the reason you clean injector ??

[@diyprojects-rd6431]

I had the engine light. The code pointed towards NoX sensor. The sensor was clean but the Injector was found clogged - shown in the video.

[@user-rv8wh8lu5g]

I have almost 3 times nox sensor replaced by dealer still have problem should I try to clean adblue injector ??

[@diyprojects-rd6431]

I would suggest that the rectification depends on the code that you see upon scanning.

[@TA-mm7rv]

No fault anymore?

[@diyprojects-rd6431]

Not at the moment - fingers crossed
