Nox Sensor - A6 Allroad

Followers

April 13, 20224 yr

Hi all,

I have had the yellow engine warning symbol coming on intermittently over the last couple of weeks.

I have scanned the car and the fault code I get is:

P229E00 Nox Sensor Bank 1/Sensor 2 Intermittent/Static

Is replacing a Nox sensor something that is within the realms of a DIY mechanic or would I be better going to my local independent Audi specialist?

What sort of money is in one of these sensors?

Thanks

I've found this YouTube video which might help:

Looking online I think the part is going to be around £200.

Hi phone Carparts in motion and get them to match the sensor to your Reg/VIN

Are S5's notorious for not being serviced?

ZeroX · Saturday at 10:46 AM4 days

Hi, following on from my previous thread, I have seen another car that I was interested in: https://www.evanshalshaw.com/search/details/used/audi/a5/automatic-petrol-white-coupe/06ce9494-f94d-f111-8fdd-000d3a874790/ When I enquired with the dealer, they said there is only one stamp in the book from February of this year, and no history at all in the Audi database. So there is only evidence of 1 service in almost 10 years. I am starting to get a bit !Removed! off with this actually, and it's real

Bose radio antenna mouse damage!

Robert Coop · yesterday at 08:53 AM1 day

Good to join the Forum. A mouse got into my wife's beloved light blue 2004 A4 TDI Sport Auto Convertible (she has had it from new) and has chewed through the aerial cable under the back seat. and damaged it in two other sections. What connectors are recommended to re-join it and are they easily sourced - the garage made out I might need to go back to the loom - surely not? The radio is the original Bose Symphony. Thanks, Robert

Alternator failure related to mild hybrid system?

I've been seeing more and more posts across FB and multiple forums about people having the alternator failure related to the 48v mild hybrid system and wanted to see if anyone has had this issue and how their experience has been. I know in USA they have announced a TSB with an extended warranty for 7 years but I am trying to get more info from Audi UK but not getting anywhere. Has anyone had this issue and if so has Audi fixed it (if out of warranty)? It seems to be tha

Kian · May 27May 27

Hello everyone, Wondering if anyone can help me. A few weeks ago my EPC light came on and immediately went into limp mode and started jumping when driving at 5mph. After a few hours I came back to the car and it was fine so I drove it to my storage unit. I came back the next day and when starting it the EPC light and EML light were illuminated and the idle was quite rough. I came back to it about a week ago and all the doors were locked, the key isn't unlocking it and the barrel of the central

Hello all, I’m a 21 year old man who has a a4 b9 and I’m currently paying around 400 pound for the car, I absolutely adore the car but the monthly payments are absolutely overwhelming me, selling it would be a last resort. So I ask, does anyone have any advice I could use to lower my insurance on it, any ideas will be much appreciated.

Can't find an interior blower for my 1994 Quattro 100 2.8E

TomMelluish · May 8, 20251 yr

Hi everyone, I've got a lovely old Audi 100 Quattro 2.8E from 1994. Sadly the bearings have gone in the interior blower, leading to horrible noises any time I try to use the climate control. I tried to source a replacement part, but the one that was sent has a different mounting to what's in my car. I can see one number on the old blower, but web searches don't seem to find anything for it: 3135102138 I ordered one of these from autodoc.co.uk: 2669I0008 RIDEX Interior Blower
