What would be interesting would be to hear what parameters are changed by the software updates. Are they simply to adapt the car electronics to a new design/manufacturer/operating parameters of the new NOx sensors or something peripheral like the temperature as signaled by that exhaust temperature sensor or the time delay to NOx sensor switch on [and thus presumably Adblue fluid addition] to protect them from moisture ?? In other words is increased reliability due to a new more robust sensor design or relaxing their operating window to reduce the chance of damage. Or maybe a bit of both??![]()
Yes i would be genually interested m8 as i run a small diagnostics business myself .
I expect the software to adjust the operating parameters so it doesn't show a warning light. That is what they usually do!
I should point out that the bluetec heater is part of the Adblue reservoir system but entirely separate unit to the two discrete NOx sensors the subject of the OP
Changing all these parts really helps the environment doesn't it. This obsession with driving down what comes out of a cars exhaust pipe seems to help those who chase this mad agenda forget that NOx sensors Dpf's , catalytic converters and even the polyethylene container the AdBlue comes in have to be manufactured using the earths resources then packed and shipped all over the world. Making them and shipping them once in the lifetime of the car they are meant to be bolted onto once is bad enough, but having to repeat the whole eco unfriendly process possibly 3 times in the cars lifetime makes a mockery of the whole scam.
Did someone in the peanut gallery mention the batteries from electric cars ??That's another story.
I had an oxygen sensor replaced in the summer due to similar symptoms and it feels loads better but I do wonder if its 100% - I dont drive the car enough as its the Mrs' so I'm not sure. It still does the very occasional low speed bad change, and the MPG seems down. I wonder if it needed the software updating. It did throw an EML about 5 weeks ago but then nothing since. I'm wondering if the garage did the software update too?I can show you the document from MB in Germany about the software updates for NOX sensor replacement if you like?
I’m so glad that none of my cars have this light to come on , hence I don’t get these pesky faults .Just had the EML light come on the MLBooked in with indy for Monday to have fault codes read. I really hope it's not these sensors. It's a 2012 350, which I think is the same engine as yours OP, ours is around the 67k mileage mark.
Be interesting to see what response you get from your dealership.
The ‘proper’ 350 , as fitted to the W108 , W116 and R107 was a V8No it's not - you are missing 2 cylinders.![]()
These latest NOx Sensors require a software update when installed, perhaps they didn't do this ?Well, just joined this forum due to the nox issues. Had my engine warning light come on, was going on for a service with MB in Poole. Both sensors faulty, MB replaced FOC, thankfully! This was done on Friday. Warning light has just come on again this afternoon! So back to MB.
Btw it's a 64 plate e class e220 bluetec.
