To dobrze bo mi zostało 120 km do niemożliwego ponownego rozruchu silnika. Dzięki.

Thank you for the video, i have the same error codes on my insignia. Can you confirm that by replacing the NOX 1 sensor the problems have been resolved and stayed resolved? Thank you, i just want to make sure that the sensor is what's causing the issues before i buy it.

We have few Opel/Vauxhall Zafira C cabs with the B20dth engine.
All of them suffer with different nox-related errors. One car gets an error if it's really cold in the winter. Faulty Adblue heaters. The other car has already adblue crystals on the exhaust and gives me both errors : P2BAD & P20EE. We changed already the adblue injector/pump and tried some aftermarket sensors with no success. It's a shame Opel wants around 500€ for a NOx-Sensor KIT, and the car has two of them.

Good video!! I have 2 DTC codes, P220A and U029D. My understanding it`s 2 NOX sensors but whitch one is failing? Thanks!!

I currently have this excactly the same code on an Astra k 2019 plate x

Hello. Initially, there were three errors: P2210, P2209, P11DB. After replacing the sensor with another used one, two errors disappeared. One P2210 error occurs periodically (approximately every 150-200 km). Is this used sensor also faulty? Do I need to adapt a new sensor after replacement? Is it enough to just erase the mistake? thanks

Raczej bym zaczął od sprawdzenia katalizatora bo często on sam jest uszkodzony i wymiana sondy nic nie pomoze

I've changed my nox sensor Bank one and wiped the fault code but 20 miles or so the engine management light comes back on with the same fault.. Genuine vauxhall sensor.. Any idea?

[McG]

I have the above codes and just checked the price of a new sensor... Is there any way of repairing it???

[mazmarcin]

Witam. Czy tak samo jest w Insignii B? Silnik D20DTR 154 kW?

Hi can you help/tell me what p11db code is thanks do I have to get the sensor calibrated

[Jelly-Mack]

I have code P11DC come up on my insignia 2.0 cdti 16 plate and i am being told its the bank 1 sensor 2 which apparently is this one in the video and not sensor 1 so i am confused as this video says nox sensor 1. And mine would have to be the bloody £380 one from dealer and ebay wtf. Any info would be a help thx as the cheaper option is to buy and fit myself

[nathanwebb]

I have the error code P20EE I have cleared the code and it hasn't come up again what would you suggest?

[berndueberschaer]

Strange video; does not show the procedure to change, but a sighseeing below an Opel Insignia...with confusing me more as making clear how to change the sensor.... a pity, waste of time...

[MrLipynho]

Hi
I have exactly the same error codes on the video, how can I confirm if I need the 1st sensor (as per video) or the 2nd sensor?
Are the error codes for the 2nd sensor different?

Thanks in advance

[losyn]

Hi. maybe you know how to solve the problem P204b?

[jrdj]

I have an error code P11CC could it be my sensor 1?

[thomaspowell]

My code is p2209 is thus the same problem
