Staring to get a little frosty and thinking I should get a cover to save my efforts in the morning, de-icing and scraping. Any recommendations?

I did mention fuel associated Greg. New sensor to be fitted. Question what make sensor is going to be fitted, or you could end up worse off. There are some pretty dodgy sensors available. 
Kind regards,

Gareth.

You did, may have been spot on. I’ll check. It’s through Audi, so you’d expect it would be good, but never assume. I’ll ask when they get it in before they put it in.

Check your fuel trims on a diagnostic scanner and see if they are off (outside of +5% and -5% tolerance) indicator number 1, then secondly check the voltage on the sensors with the same scanner as the car i running and if the voltage is not fluctuating thats a secondary give away that a sensor is faulty

As it was still under warranty I took it in and they’ve confirmed it was the sensor. And it’s covered 👍

So awaiting for them to get a new one in stock. Funnily enough, since I switched to Premium Unleaded (one fill with Shell and next with Tesco). The light hasn’t come up since. Oh well, new sensor coming.

Thanks all for your replies

Hi there is miles of difference between the two, try a tank of Shell V Power and enjoy the non surgical smile it produces, the alternative [cheaper] is use an Octane booster Hydra and Archoil do some really good versions.

Funnily enough having dropped that into conversation and went onto read more about it and apparently soo! In summary it appears, keep away from BP Ultimate, and it’s between Tesco Momentun and Shell V Power. Not heard about the boosters but will do some reading this eve.

‘Re-fuelled it and the light came on…..’ 
Simply fuel quality associated? 
Kind regards,

Gareth. 

Again, is there much noticeable  difference between unleaded and premium unleaded for day to day driving?

If you've cleared the code a d then the same code has come back then I'd be confident to say change the sensor. If it still comes on after the sensor has been changed then further diagnosis will be required 

Yep that’s what I’d been made to understand. Will take it and see what comes back from the investigation.

Hello Greg,

If the car is under someone’s warranty, then I wouldn’t be taking on any responsibility for (messing around) trying to diagnose or fix anything if it were mine. You make it easy for them to counter  claim you may have influenced the issue. 
Kind regards,

Gareth. 

Think I’m with you in this. Was double checking myself as I’d read it was a regular occurrence with the C7

Not yet, wasn’t confident to just change it without some opinion on whether that was the best place to start. It’s under Warranty too, though I’m guessing a sensor is non-mechanical. 

Afternoon, 

I've got an RS6 C7, recently bought. The engine light has come on (yellow) and the OBD shows error code P2196. It's the second time it's appeared both times after filling the car with fuel. I understand that it could be caused by an 02 sensor. I reset it to see it would come on again. Car ran 350-400 miles, I refuelled it and it's come back on again. Anyone come across this? 

At long last - my dream ride!
