P229F, P20EE - how to replace NOx sensor 2 VW Sharan 2.0tdi (Seat, Skoda, Audi)

[@sjorsdw]

I also read often that cleaning the adblue injector can resolve the P20EE error. Im having this done.. fingers crossed that will do the job. If error returns, its probably replacing the nox sensor for me. I imagine a second hand one on ebay could be much cheaper.

[@wawayltd]

Yeah, cleaning is worth doing as it's so easy. NOx sensor price is ridiculous.

[@christhackrsy]

Just done this on Alhambra had to do scr efficiency test with vcds to clear lights , takes 15 mins to run test, you have to press brake and throttle for all that time!

I have the similar vehicle like yours. My problem is I have a p2237 o2 sensor bank 1 sensor 1. Now I have changed the Nox sensor before the Cat converter but the same code keeps coming back. Do these cars have Nox sensor and O2 sensor separately?

[@wawayltd]

I'm not 100% sure, some manuals show more sensors for some cars than others. If you would be looking for Bank 1 Swnsor 1, it would be the one that sits on a top of DPF. Is that the one you have changed?

[@radwanmiah8150]

@@wawayltd I have just realised there are 2 sensors at the top before the Cat. 1st is O2 sensor and just below that is the nox sensor. So I'm guessing there must be 2 sensors after the Cat also.

Hi @WheelsAndMotors, I had the same error come up on my Audi, I cleared the code and went for a 30min drive and the codes did not reappear. Could it be just a one off fault code (just VW things) or would you expect it to come back straight away after clearing the original codes? Thank you

Do you reckon the first error is related to the second? Do you have any videos on replacing that sensor? Thanks in advance!

Sensor 1 is easy - it just sits on a top of DPF and it's cheaperthan sensor 2. Not sure if these errors are related. I have a video about AdBlue heater.

[@wawayltd]

I know very little about Mercedes. Bank 1 means - cylinder head, like V-shape engines have 2. If it's E220, I believe it is a 4-cylinder engine, so there's only one "Bank". Normally engines have 2 sensors - Sensor 1 would be somewhere after turbo, Sensor 2 I would try to find after catalytic converter - have a look along exhaust pipe.

Nice instruction video. Just got a notification about this video before going to dealership to fix the same errors and replace NOx sender. Do you use a torque wrench to install new sensor? I believe it is supposed to be installed with 50 Nm torque.

[@wawayltd]

It's pretty much impossible to get torque wrench in there. Had to go with the feel. 😏

[@peterdze]

@@wawayltd Same thing in LV and pretty expensive with limited range. Probably worth it to buy a couple of these with different ranges if you service a dozen cars in a day: VW manuals are full of torque numbers for almost every manipulation including screws holding trims or navigation module.

[@wawayltd]

@@peterdze No no, I meant it's difficult (impossible) to use torque wrench on that sensor due to limited space. I don't have problem getting them for myself, I have 3 - 1/2 3/8 and 1/4. All together ranges from 5Nm to over 200

[@peterdze]

@@wawayltd I see what you mean. Indeed, took a picture of the sensor and it looked cramped to reach with a torque wrench. Opted to go to a dealership for a peace of mind, but after watching your video it doesn't seems to be so complicated (as usual when watching someone more experienced doing the things 😉). I only bought electronic torque screwdriver to do simpler things like removing navigation module to clean laser lens and reassembling the whole thing afterwards, at least failing there would not stop the car 🙂.

[@filipslisko703]

Hi ,I have the same fault on my 2012 SH, reported it to VW ca 25000 km ago,and now were on 2nd service after that I have reported ,were I stated that adblue is not used by car (did it several times but vw says it is normal that car does not consume it ????),and they pointed out that i need to replace sensor.I was not the owner when update was done and I have some doubts that after software update everything on the engine regarding emissions was deactivated(is it possible to do it at all ?) All of the original installation is on the car(egr,dpf,adblue tank,nozzle,lambda,nox1,nox2...),so I am not sure what to think. It is not possible to force regeneration and the km , time etc is always the same since the last regeneration. Adblue tank shows 65 but it is full. Can you please advice

[@wawayltd]

Regarding AdBlue - my car started consuming significantly more of that stuff after diesel scandal re-map. I can't say that I like it. I hate that this Adblue system is so temperamental. Anything it doesn't like - it starts mileage countdown! Ridiculous! It doesn't even affect cars performance or safety! What if I travel (as I do) between England and Latvia and this shit happens inbetween, and I have 600 miles left and we're not going anywhere?? Just because of stupid tank of urine (chemically AdBlue is very similar to urine)! As much as I love and adore my Sharan, same much I hate this AdBlue system. So if my car would stop consuming AdBlue, personally I wouldn't worry about it. Regarding DPF regeneration. DPF sits before AdBlue injector, so AdBlue shouldn't affect regeneration. Obviously, if DPF is working properly, it needs to regenerate time after time, otherwise it can clog up and cause all sorts of trouble. When it regenerates in my car, I only notice it by increased idle revs and stinky smell. When you drive you may not even notice it. If there's a problem with DPF - car would notify you. I have seen cars with cut out DPF when only inside is taken out, but on the outside it looks normal with all sensors to pass MOT. My car has all ecology components that you mentioned working, and I'll do my best to keep it that way. Regarding Nox sensor. Sensor 2 is ridiculously expensive, on Internet it can be found much cheaper... But in your case, I don't know what to advise - I don't know whether that is faulty sensor, or bad NOx readings because of not working AdBlue.. Don't know, if you can get sensor somewhere for cheap to replace it and see if it helps.. Sorry my friend - I gave you load of text with not too much help..

[@filipslisko703]

@@wawayltd well,thanks anyhow. I have ordered NOx sensor 249 euro, and I have also bought VCDS from Ross-tech. I will play a bit I guess. Like you said I love the car ,I hate the emission scandal(tried to sell the car,2000 views not a single call,all because E189) and f.....g adblue. The car will not deny start if the oil lamp is on,but will because adblue is on. If I find something out I will notify you.

Yeah, see what can do, before you spend any money. That sensor is ridiculously expensive. My code reader was directly pointing on it. I'm not as clever as I pretend to be in my videos. Try forums or Facebook groups like this one: facebook.com/groups/1463201880401563/?ref=share

I went for genuine sensor because I use my Sharan as a taxi, I didn't want to risk, because I depend on my taxi work so much and can't lose days off work. If that would be just my private car, I would consider third party looking at their warranty and returns policy.

On my Sharan 7N 2015 I checked with OBDeleven and I get the same codes. After I stop the car the ventilators from radiator are still working for another 5 min aprox. Could be this sensor the problem? Trouble codes: P229F00 - NOx Sensor Circuit Range/Performance Bank 1 Sensor 2 Intermittent P20EE00 - SCR NOx Catalyst Efficiency Below Threshold Bank 1 Catalyst 1 Intermittent Thx!

[@wawayltd]

The reason why ventilators kept working - most likely you stopped the car during DPF regeneration. And because it gets hot, if it stopped before process is finished it keeps ventilators going to cool vulnerable places down. It's normal. All vw with DPF do that. As for your error codes. I had the same - I solved it as I showed in the video. However, I can't guarantee anything - just shared my experience.

I have an issue on my 2013 Sharan 2.0 TDi where I am getting the countdown on the Ad Blue but the Ad Blue tank is full?? could this be connected to a Nox sensor fault? Thanks

[@wawayltd]

The easiest thing to do first - put ignition on for at least 30 seconds without starting the engine, that should let ecu to "understand" that the tank is full. If that doesn't help, then it's quite common issue that I hate a lot. And I don't have a straight answer what to do. Manual says that if AdBlue sign comes with an image of a spanner, there's an issue with AdBlue system and it needs to be fixed. Scan it to see what errors does it give you. Last time I had this problem, error pointed at this sensor, I replaced sensor, but countdown still was on. So I found someone with VCDS and he reset it for me.. Now I got VCDS myself, but I didn't have to use it for that purpose yet, because I never have AdBlue tank empty. As much as I'm in love with this car, that much I hate this AdBlue system! I've got a link how to reset it, but as I said, I didn't try it myself yet. Here's the link: malonetuning.com/how-reset-adblue-2011-vag-ecus
