Today, DSC failed me!

I'm not taking mine out in these conditions anymore, had far too many scares over December, even under the lightest of acceleration and in Eco Pro mode with minimal throttle response it just feels far too dangerous. Starting to regret not getting a 4WD now, I had no idea just how awful RWD is in anything but dry roads.

:confused: Really? Sounds like there's something badly wrong with the car: any modern RWD car on decent tyres really shouldn't be scary in anything other than ice/snow. I've been driving my RWD cars all over the place and haven't had any problems, even when I've been purposely being stupid.
 
A few stories have emerged about Cruise Control flinging various cars off the road during hydroplaning - don't suppose you had/were using CC?

Errrrr what?
 
How much tread on the tyres? Doesnt matter what they are if they can't shift water.

Good it survived though, those Z4s make for good lawnmowers it appears :p

Off to drive through big puddles, with no DSC ;)

The rears are about 6-7000 miles of, I guess 4-5mm at least, the copper on the scene checked them and wasn't remotely concerned so I'm confident in the roadworthiness of the car.

The breakaway was instant not like a small dive followed by a tank slapping driving fail, it whipped me straight off the road, having notched up another mega stint in another s2k I'm reasonably keen to point out I've experienced most things on the road. I've also done nearly 20k in the z4 already :-)
 
Hmm very interesting incident.

I am tempted to say that the road was probably overtly slippery...due to a spill or something and you lost the back end.

Hitting standing water is enough to send the front end darting to one side, followed by a slight overcorrection and perhaps not being 100% alert (no one can be fully alert all of the time), leading to the car ending up in the weeds.

The road surface probably wasn't massively slippery and he wouldn't have lost the back end unless he was nailing the throttle or hammering the brakes (or turning sharply!) - neither of which are likely on the motorway whilst travelling a steady speed.

Standing water is dodgy stuff and can be a lot deeper than you expect.

Glad to see you're ok, and the car is relatively ok too! Have a beer or two tonight - you deserve it!

Anything but the lightest throttle response in wet roads and the DSC will kick in and go crazy. Overtaking in this weather is a big no. I went past someone at the beginning of the month and it just slid all over the place as I was going past. I know it's a powerful car but I was being gentle with the throttle.

Also I've noticed on the motorways the far right hand lane can be completely waterlogged in the current conditions, which means bombing through it at 70-80mph is indeed an accident waiting to happen.

Like, seriously, grow a pair.

Possible, but DSC will switch off CC if it detects anything approaching slip.

You have a modern M135i with 320bhp and lots of electronic aids, not a 550bhp Ferrari F40 - stop being over dramatic.

You either don't know how to drive or your car is seriously seriously broken. I just had a good stint on some back roads and the car didn't feel anything less than planted - if a little bit squirmy under braking.

Honestly with 420 horses going to the back wheels I can count on one hand the number of times DSC has failed to correct slipping on my car and I have had to correct it myself.

Perhaps add some fuel to your car to add rear axle weight, check your tyre pressures, alignment, tyres etc.

I guess having a turbo doesn't help when it comes to weather like this. I remember the Golf GTi would love the cold air, generating even more power when you needed it least!

You want to get it booked in ASAP, either that or getting your throttle controller changed from a digital one to an analogue one.

Nailing it in 2nd gear leads to copious amounts traction control, nailing 3rd is pretty much fine unless it becomes very wet just as you hit peak power or hit a bump.
 
Well I'm taking the sensible stance that in this weather unless you really need to be out on the roads, you shouldn't be. It doesn't matter how good a driver you are or what you are driving, you are not invincible and the conditions are horrendous in the South East. Will Gill is a much better driver with a lot more experience than me but in the current weather accidents like these can happen to anyone.
 
I find with 350 HP and 700 Nm, like Gaygle, unless I'm in 1st or 2nd it's not usually an issue.

'Conditions are horrendous' - are you for real? :D I'm in the South East and it's.. a bit windy and rainy. That's it.

You must be a right raver..
 
Did 14 (yes fourteen) miles on the M5 yesterday and couldn't wait to get off it. It was awful, absolutely rotten driving conditions and useless moronic idiots doing well over 70 along it in their 520ds.

Do love how much grass and mud you scooped up though. :D
 
...I had no idea just how awful RWD is in anything but dry roads.

Melodramatic to say the least. :p

My RWD E39 feels nicely planted in all but ice and snow and I'm definitely no driving God. I just take it easy and drive according to the conditions. Common sense stuff really.

Sods law I end up in a hedge tonight.

I was just about to go out and make a journey to absolutely nowhere for no purpose whatsoever but now I've read this advice, I will wait until I need to go somewhere first.

I've been out every day for the last couple of weeks and I haven't even died a tiny bit. And about half the time I've been in a RWD car with ditchfinders and NO DSC!!!!111!!11! :p

In all seriousness though, I'd get your car checked out as what you're experiencing really doesn't sound right.
