Thanks so much for this. Super handy and helped me fix my Trafic which had the same issue. I got an Autel AP200 Scanner which identified it as the downstream nox sensor. Thanks for saving me having to take it into Renault.

So my 2016 1.6 renault trafic "check anti pollution system" light came on. I have OBD II so i cleared all the fault codes and then the light came on after a day. I checked again with OBD II and now it shows me Glowplug circuit A malfunction but NOX sensor fault is gone, light is still on. How are those 2 linked? Starts little rougher than before, no white smoke, idle fine, is not in limp mode, drives fine.

@ace1rtp 8 месяцев назад

Hey there. Great video. I think ive got a similar issue. My 2019 diesel Vivaro van (60k) sportage is showing a adblue emission fault, and will be impossible to start at 600 miles.? Ive topped up fluid and problem still showing.? Please advise.? 🙏🙏🙏 Time of year is expensive, and don't want a huge garage bill, so if i can do the sensor replacement I'll give it a go. TIA. 🙏🙏🙏

@bjrnulstrup5420 Год назад

Hello and thanks for your video My 2018 vivaro have a fault that says bad AdBlue in tank do you know what that could be ?

@tomsurrey2252 9 месяцев назад

The problem is, where did you get the adblue from?? IF you've got it from a petrol station then likely, as not, it could be out of date OR, been left on the forecourt and the sun has got to it so, ALWAYS buy it from a proper retailer... make sure the date, on the tub, is not out of date also look to see if there is any 'crystallization' around the filler cap, of the tub... if so, get a different tub!

@andywood3069 Год назад

I have had my local garage and perrys look at mine and all they have done is force regeneration, check anti pollution has just come back on but I seem not to be using any adblue still at 100 percent any ideas ( I only have an autel maxi scan)

Hi my anti pollution light came on just today. I will have to do the service in couple of months. Do you think is ok to drive until then ? Also when driving now i can hear a click noise come from driver seat looks like a tock from a clock or something like that. Any idea what could be? I have a renault traffic 2016

@cupra2Jock. Год назад

I've had my vivaro 2017 scanned and NOX sensor 1 was the issue. just spent £341 on a a genuine vaxhaull one, how do I get the light off? do I drive it for 15 miles down the mot at 60mph? or do I need to turn it off properly with main dealer? pain in the ass this. any help would be appreciated.

@diydaly Год назад

You wont need a main dealer but the code will need to be cleared using a decent diagnostic machine.. a basic eobd reader will only read the engine ecu where are a nox sensor fault is likely to also be stored in the denox ecu.. only a decent scanner will be able to read into that..

@trx8503 Год назад

Great videos. I've subscribed! I have the Renault version. Only 40k miles and egr cooler needed changed. Pretty standard apparently. Big job; had to drop subframe. Now I have this Downstream NOx problem too. Faults in the Urea dosing module but they were DF055, DF065 and DF066. Could be just corrosion in the plug terminals though??? I'll try cleaning them first. Constant probs with these 1.6 biturbo R9M engines. Would you recommend egr and adblue delete? Would save alot of grief and money!!!

@diydaly Год назад

Thanks! yeah they seem to have a lot of issues! both the EGR and cooler are mega common and like you say not easy jobs to do, the EGRs tend to be seized in too 😖. personally ive not had too many add blue issues.. We've have one customer that's had an ad blue delete done and its caused quite a few issues so in my experience I wouldn't recommend it

Hi. I am trying to leave UK on way to Spain in my 2016 vivaro. Anti pollution warning just came on. She is at dealership, no fault codes. had dpf regeneration, all ad blu is testing ok and still no codes but warning lights and 600 mile limp. Feels like I am throwing money at no solution. My mate has changed these sensors on his movano camper and is saying he could do them. Obviously a lot cheaper than dealer! But would codes clear? Should I leave her at dealers? Anyone down south you would recommend that might be able to pick up codes or help? Thanks. Sarah

@diydaly Год назад

Really odd if its got no fault codes! I have heard the movanos are having some problems with the software relating to the add blue level.. we had one that had the countdown and no fault codes stored.. it went to the dealer for a software update but haven't heard if it fixed it or not yet

@sarahkeast2943 Год назад

@@diydaly Thanks for getting back to me so quickly. The dealer has found a code now for my Vivaro, it is one of the Nox sensors. I have asked them to fix it [and rob me blind] as I want her to have the best parts and not risk more stress on my trip. The whole process has been an 'education in patience'. I will be getting a Boxer/Ducato on my return from Spain and will be looking for a specialist van mechanic to do any bits as it will be my full time home and dont want this stress again!

Hi. I've just got a fault on dash saying "check stop and start" with the engine light on and spanner. also it does come up with anti pollution system to but goes off when i drive. but the stop and start warning stay on. Could this be a battery problem? I've just had the battery tested and the guy said it should be running over 80% but it was 77%. So could this be throwing everything out? Also I dont have adblue on mine, Thanks in advance. ste
