Hi

I've recently bought a 2016 Audi S8 4.0T which is Stock. I'm entirely new to VAG/Audi.

I have a MIL on the dash for Rear Sport Differential Fault. Upon reading the codes it looks like it may be electrical failure in one of the diff oil pressure sensors (Black and Brown plugs). I'm keen to know which it is / Part number. I've run some logs and one (IDE02035-ENG98502) is registering 0.5Bar Pressure engine off and IDE02036-ENG98502 is 0.0 Bar - both have 5V. I've sprayed contact cleaner into the plugs (more in hope than anticipation)... I cant get a response from the module to run pressure tests etc in Basic Settings. I gather that I shouldn't replace more than one at a time and that they need coding to the car...

Any advice on diagnosis and repair would be appreciated:

I have found only one other example of someone approaching this:


and this excellent guide:
D4 rear diff sensors.pdf

But just want to know the correct part number and how to do the readaption process..

I may be better to just bite the bullet and go to Audi Stealership.

I did think it was the Oil Temp sensor, but when I looked at the measured values the temps were measuring - albeit 1 degree apart.

The pressure wasn't measuring on one.

I'll get the measured values this afternoon - thanks for your help!

Yep, although the formatting is a little off compared to mine. Also update your VCDS :)
In any case, you have a temp correlation DTC between two sensors that read the exact same temp at ambient. I'd try and catch one "in the act" before you start replacing and re-adaptating them at random, because getting in there isn't easy, nor is the re-adaptation trivial from what I've read.
*My* next step would be to clear the DTC, then log both temps and pressures:
Code:
IDE02033 
IDE02034  
IDE02035-ENG98502  
IDE02036-ENG98502
and maybe as a reference:
Code:
ENG109371-ENG98502
ENG109372-ENG98502
during a drive where things get nice and warm, and hopefully the DTC triggers and you can correlate the freeze frame time to a specific location in your logfile once the drive is over.
Best case you'll have a sensor that goes full negative and that will point you with certainty to that sensor OR ITS WIRING :)

Thanks.

When I first logged there was a 4 degree discrepancy between the temp sensors. But it tidied itself up again when I saved.

I'm unable to clear the DTC, it immediately pops up again after clearing. Any ideas?

For the measuring values map, you should be doing Applications->Controller Channel Map .
Before it "tidied itself up", which temp sensor was further from ENG109372-ENG98502 Temperature QCU-Data 9 °C ?
If the DTC won't clear, then you can't use the freeze frame time to pinpoint the issue in the log of your test drive, but that does not make it unusable; you just have to look carefully or plot the data.

Since you mentionned it tidied itself, you may also to start the log and just shake things under the car. The dual sender coolant temp sensors on some Mk4 were notorious for failing as you wiggled them.

I'll give this a try..

Took it to Audi Oxford this morning as part of a recall. They ran their diagnostics and recommend changing the Control Unit (J492) and both sensors (G437 and G640) at a cost of £1.1k.. The tech did admit that this is the guidance and they don't just replace individual sensors!

Rather try a DIY and save circa £1k

Looking at my log it seems one of the Temp sensors is uniform in rising temp where as the other is spiking up/down at certain points:

Is it fair to say that sensor1 is my problem?

Audi wanted to replace both sensors and the control unit.. Guess this didn't include any wiring...

That's the classic assumption that many people make - if there's a fault then replace something without checking the wiring first, which can be an expensive mistake.

Fair point, but if the sensor is consistently reading 5V and continuously reading a temp - rather than N/A or Zero then surely the wiring would be sound. I've done a visual inspection of the wiring as have Audi investigated as part of their diagnosis.

Currently the MIL has gone away and allowed me to clear the codes. I'll wait for these to return before doing anything further.

OK, this is a good time to now go to the wiring and wiggle it around, or even pull on it a bit or check where it is fastened ..... if you get a fault then it is potentially the connection or the wiring. Also, when you unplug the connectors, use some dielectric grease on them! You could easily have a bad connection, and..... never say never when it comes to wiring (be sure to look for perforations also). Sounds like it is a "moving target", keep a open diagnostic approach.

Regarding your voltage check, sure its ok..... at that moment!

The dealer is revealing to you that it uses a "parts cannon approach" ie, change everything! That isn't diagnosing the problem. I would take what they say with a grain of salt! Unfortunately, if there isn't much or any profit in it.... they don't do it.
Be patient and think creatively!

BTW, I seem to recall Jeff from RT helping a "user" regarding testing a circuit/wiring : DVOM vs. test light with (incandescent bulb type) If you have a partially severed / broken wire the DVOM will read "normal" values ; while if it is tested with a test light and thus carry a load (bulb), it may not illuminate or be unusually dim. ???
