Title: UO20D CODE
Post by: raywilb on 03 January 2023, 22:21:22
 the dreaded UO20D code appeared again today so deleted it again & once deleted alls OK for quite a while . my query is knowing its a communication code does BanK 1 refer to the sensor ??     wishing all oof members all the best for 2023  :y

It's a straight four pot. Having Bank 2 pop up would be something of a surprise  ;)

   ok ,  not as knowledgeable as you fellas but i will have a go at most things . i will take it & get the nox sensor checked out

I think thats a DPF pressure sensor generic code, needs reading with a tool more customised to the Manufacturer to get the sub code and more detail

Just had a little chat with a PT contact here.

Apparently Shitroen use the very poor Conti NOx sensor setup which has a sensor and mini ECU located close together, he says the ECU is very pronce to water ingress and is likely the issue. Apparently they come as a matched pair (ECU and Sensor).

Being a NOx sensor it should easy enough to get at and change, the cost however might be a few hundred quid for the part

  I did once mention about it first happened after driving through water , no garage near me want the job so next Tuesday i am taking it to Wakefield to a guy thats really good with the computer analysing.

Who will tell you that the NOx sensor has had a fit...

  Its almost a 50mile each way trip to where I am going on Tuesday , but i know I will get sorted. at the moment no codes present. tho been in that situ twice before.

Is he replacing the sensor then?

  if faulty it will be changed. the warnings have never appeared  whilst mobile & because of that i am not sure , I would have thought if the nox is kaput the warning would appear every time i started the car,

No, every time the crappy designed Conti NOx ECU gets a soaking.

Needs changing, or your trip will be a wasted one  :y

They are a combined part and ship as a set, the ECU is apparently calibrated to the sensor:

Yeah, what could possibly go wrong with that setup ;D

So a device designed to save the planet actually causes more harm due to such a daft design. Quality.

From what I am told, if you crack the top off the ECU once they are a few years old, there is loads of water damage as they are not well sealed (in fact looking at the casing retaining method, its not surprising!). So when they get wet they have a wobble, eventually the wobble turns into a permanent fault

Yeah ,lets strap a small ecu to the floor of the car 6 inches off the ground, what could possibly go wrong ::)
