Does anyone have issues with their traction control?
In normal / normal mode but manual I assume all systems should have maximum effect - a few times in the wet I get the back end out on acceleration - this morning I pulled out to overtake a lorry in 3rd gear, accelerated the turbos spooled up and the tyres gave up their grip very easily resulting in me overtaking with opposite lock applied! Its easy to control but my fear is it colud happen on a B road as I accelerate and cause the back end to slide into an on coming car. I enjoy this level of freedom with the car if I had it in sport or track modes but when you need the reassurance of all systems then its not so good - especially if the wife was driving it....

Is this normal or should the TC be more effective in normal mode?

Does not seem right. Have it checked but I lost the front at 30 mph with no TC and concluded the tyres were cold. So do you know what tyre temps you had in the rain?

I do not trust the PZ's in the wet and cold.

I only ever a small slide in sport under hard acceleration but never enough to get it sideways.So in normal it souldnt happen,but 600hp on a bit of oil and water it might never be quick enough.,Could be just a one off?? with the road conditions

Temp was about 5 degrees c and wet so not the best of conditions but I would have thought the systems would have just limited the power? It was in active aero mode so not sure if that has any effect?

I can repeat the wheels spinning at any time by flooring the pedal in 2nd gear in the wet - the back end spins up quite easily regardless of the sttings on the car. I have felt the TC cut in in the past in the dry if pushing too hard on a 2nd gear corner but maybe thats more to do with the stability control?

I've just passed the 620 mile mark and want to open it up but its wet and slippy!!:(

This reminds me of an exercise that Aston Martin do to demonstrate their stability management speed of reaction.

Two demos at Millbrook.

On a flooded surface, standing start. Floor the V12 throttle and make turn out of a T junction. SM on no problem.SM off , wow your out off shape and the inertial force is very big.

With inside wheels on wet grass and outside wheels on Tarmac/concrete at 70 mph hit the brakes as hard as possible. No drama. Then from standstill floor the throttle. Some shimmies but in control . Very impressive.

Wonder how the MP12 would perform.

Have a look at the tyres. When I first got mine, all was good. But this week in the wet and settings in N & N, Auto..the car seems to step out a little to easy...But I know my tyres are GONE...

For me, the best position in the rain is handling-sport and drive train-normal,
If I am honest I put handling always on sport, helps with bottoming out and doesn't make me sea-sick like the N position. And for the traction control I suggest to be really gentle on the gas pedal- throttle- and don't try to rely on too much electronics. I have to say that almost all the car manufacturers and journos alike try to make you think that a car is undriveable without all the driver aids on. I beg to differ, I have been in all sorts of trouble on racetracks because of strangely abbreviated s*** . For everyday use it's allright, and highly recommendable, but don't try any strange antics and think the electronics are going to save you. If you want to learn to drive, and want to get to know your car go to a safe track and turn all the abbreviationd off, and try it.

When I say spin easily I'm not trying to push the car hard - I was overtaking a lorry that was doing 45mph - I pulled out in 3rd not 2nd and put my foot down. There's so much torque around 3000 rpm that the traction went and I was on opposite lock.

I have tried to repeat on the way home and it seems like the TC is there after the wheels have spun for a while. In a straight line accelerating from low speeds in 2nd the wheels spin then the TC light comes on and they are reigned in. This is what I would have expected in the track mode to allow some fun but the safety net is always there. In normal I would have expected the TC light to come on before the wheels spun. At the track day at dunsfold it was wet and I don't remember the same thing happening.

In an M5 its almost impossible to go fast in normal mode as the TC light is constantly flashing and cutting the power - zero wheel spin no matter how hard you try

I know, it isn't like I don't understand what your talking about, I have experienced the same thing several times. I personally think it has something to do with the response of the car to a sudden burst on the throttle, no matter how fast you are driving, but mainly when driving slowly or slowish. The car picks it up as a kick in the backside and subsequently kicks the backside out, no matter what position of the switches is. So I began to treat the throttle with kiddie gloves and since it didn't happen again. Me to I have BMW and it's true, DSC is much easier to rely on, but still, hang in there, learn to know the car and ultimately you will learn to love it. And thid is coming from someone who had to peel one from a wall.

You CAN get wheelspin in Normal handling mode, even in the dry. TC is working as intended, it is just less crude/intrusive than some other cars. Therefore, in the wet or otherwise very slippery conditions, you have to take that into consideration. Also keep in mind that when Powertrain is in Sport and especially Track, throttle response is sharper so you are going to spin up the motor faster for a given throttle pedal pressure.

Thanks for the replies - as long as its normal then thats great - it makes the car feel faster and more fun not the sanitised supercar some would have you believe. I generally prefer the TC to work in this way as the intrusive nature of some gets on your nerves.
I now know to be ready for it and so will enjoy it more.....

Yep, it's one of the most enjoyable aspects of driving the car. But, just have to remember that ESC was calibrated by Chris Goodwin, not the legal department!
