| Unintentional sideways D3 |
|
Yesterday going around a large dual carriageway junction roundabout somewhere around 30mph in the wet (normally one I'd do quite a bit faster in the dry) I detected that the car felt unstable.
I lifted off and the car went considerably unstable with a pronounced sideways drift. I corrected the slide with power and a little steering into the slide - no probs.
My M3 has no problems with such stuff unless you're being silly, you feel the DSC etc sorting it all out and it's all fine.
I am assuming there was diesel on the road for the D3 to have been so bad - this never happened in my 5 years of D2 ownership.
What I am curious about is how to advise SWMBO. With all the computer wizardry in the D3 I would have hoped that it would not have allowed the drift in the first place. Or am I asking too much of the stability control to correct a drift on wet diesel with a numpty who lifts off. Would the stability control have kicked in better if I had kept the power on?

Sometimes I think the physics can beat the electronics. I've never had the DSC cut in on road only off. It does seem to me if you've got no grip then it doesn't matter what gadgets you've got, you still have no grip DS3 TDV6 HSE - Silver with Alpaca (old one) Gone

Edd, was it possible that there was diesel on the roundabout?
The D3 shouldn't break away like you mentioned, due to the DSC, but if there's no grip then it will

Oh yes, my conclusion was that there was most likely diesel on the road due to the zero grip situation and I realise that there is a certain point where physics wins over engineering. But I just found it strange that I felt nothing happening in this slide. I normlly feel DSC kicking in nicely in my M3 - and not just like old TC by cutting power when there is no grip - I feel interesting tugging sensations through the steering etc.
My question really is does the DSC in the D3 work better in 'power on' situations rather than 'power off'? 2008.5 D3 HSE, Stornoway, Ebony

Cambers really do push physics against technology. I regulary throw mine around a local roundabout which has a condsiderable adverse camber as you join it and, even in the wet, the D3 holds on very well indeed. 21 year LR veteran > D2 GS 2003 > D3 S 2006 > D3 HSE 2009 > D4 HSE 2013 > D4 HSE 2015 > D5 HSE 2018 > DS HSE R-Dynamic P300e 2021

Power on the D3's DSC really does work very well.
There is one corner going out of town where the road rises as it turns sharply left. With power on in the dry it just hops round... if slightly wet to wet / muddy the DSC kicks in very quickly and reduces throttle and applies the stop disks. Its fun  repeatable (which makes it even more fun) and impressive.
I have noticed that power off the DSC is less prone to kicking in. Especially in the snow.
