Then run the car on the rollers you get about 3 runs i think it was.

I shall try and find it again the exact way of doing it

Dont forget you also must , have one trouser leg rolled up , stand dead straight with you arms out like a tree , and hum the theme tune to the A team , and then hey presto it should work fine

I wouldn't worry about silly rolling roads - just go on how it goes in real-life. You'll know if it's got a problem or not. And if it's fine then all a RR is going to tell you is that by their estimation it produces what you thought it would anyway.

The procedure (I didn't invest more than 30 mins, unlike JT that did and he cannot share on a forum...) is :

1) car off
2) turn key to position 2 (everything on but engine off)
3) press DSC button for 2-6 seconds
4) press sport mode
5) start the car
6) rev car to limiter (it will stop at 6.5k, still)
7) turn off car
repeat 1) to 5). The car will now be able to rev all the way to 8k


Alternatively, with the BMW GT1 :

DMS-> Test plan -> Service Functions -> 12. Dyno/Rolling Road function.

I will be able to confirm the above with a video soon that I will dyno the CSL in Sportec http://www.sportec.ch which is 10 mins from my home

GT1 is the easiest way! few clicks and no wondering if you got it right or not.
