Ok never had a 4x4 car before.
PS4 standards all round newish.
Had understeer going a little fast into a damp greasy corner.
On a normal front wheel drive or rear wheel drive car I can deal with this but on a Quattro, what's the best course of action.
Keep going, let the electronics sort it out or come off the accelerator.
S Tronic box
I know, slow down, but this was a mistake.
Thanks

Thanks so far. It's a proper constant 4 wheel drive A7 3.0 TDI 300+
It was only the front that went., which suprised me.
I'll take the early morning roundabout advice. There are some huge one's on the way to work.
I'm thinking also the temperature has just dropped so my Michelins have stopped working!
I really wasn't sure how to react?

Thanks Reg
That was super informative.
All taken on board.
Great Video by the way.
The car does corner brilliantly on Standard PS4's, but I appreciate its no sports car!
2+ Tons.
Very different on a greasy road, rather than just a wet road!

Some good information on here, thanks.
My problem started when 'I found myself in the middle of it all's
I'd already made the error.
It is a stiff car, and I did let off and it did fix itself.
However last night I went back to the roundabout and behaved very badly.
I learned this.
When the understeer happens, floor the Gas.
It immediately found grip, and control came straight back. I managed to steer it around with out any fuss, just a bit too fast for normal traffic !
After half a dozen goes I think I'm in charge of it now.

Flooring the gas is not a standard reaction though and in a real emergency will you remember, because it's not natural smile

I guess with an active 4x4 system, flooring it spins the front wheels up and the car reacts by cutting the power to front and transferring it to the back. Hence doing the same as coming of the gas, but in your case, you'll end up going faster!!

A very good in fact massive point.
When the st Hits the Fan, its remembering to do what's NOT natural!
Ha Ha Fingers crossed.
I guess Winter will be a good Teacher!

During spring 2018 (beast from the east) I met a q7 in a lane.
The q7 wasn't able to slow down..the look of horror on her face when she realised 2.2 tons plus summer tyres (adding 4wd doesn't change anything)=difficult to slow down on snow.
Thankfully I was in a fwd car with winter tyres and was able to stop, select reverse and back up to a place wide enough for her to pass as the q7 kept on it's titanic course.
No, I am not exaggerating.
It sounds like you are from here!
How much time did you have to do all of these manoeuvres whilst this 2.2 Ton car was bearing down on you?
Imagine if you have had 4WD and not FWD with Winter Tyres?
You could have 'Looped the Loop' and not have needed to stop for the 'Fairer Sex' !
Just interested like!
