Clutch slur/slurry?

[cslbecks]

I "reset" mine today by doing 50mph and pulling in both paddles - after about 2 secs i felt the car slightly hesitate as if it had done something - so i assume this has reset things. I then tried to drive the rest of the way home at full tilt, traction off and S6, banged up and down the gears full throttle etc. That said though, if anything it felt more sluggish than before!!?? Maybe it needs a few more runs flat out?? Im at Brands on 25th so maybe that will sort it out??

The only thing I can see in the manual about resetting is when you have changed a tire or had snow chains on.

It says drive above 20mph, select N and then hold both paddles for approx 2 seconds.

Or do you do it when it is in drive, S6?

I've spoken to a BMW teccy mate this afternoon (having looked in the SMG handbook for the information given earlier in this thread)

He's not aware of any such system adaptiom for the SMG box. I'm popping in to see him tomorrow to see if any such information exists.
I'll update you as and when.

He did say that when the system adaption is carried out in the workshop with the computer hooked up to the car that you hear all sorts of clunks and bangs as the system selects gears and measures the clutch take up point.

I'll withold judgement on the "two paddles held in at the same time adaption process" until I know otherwise categorically, but it doesn't sound encouraging . . . .

That's right. You only only need* to do it when changing tyres because it resyncs with the rolling radius of the new tyres.

If you want to 'reset SMG' then a dealer can do it (SMG teach-in, which is what Xporker is talking about above). The paddle thing will do jack-shit for the old 'slur issue'.

* saying that I only experienced a problem once in over 6 years of SMGII use where the paddle thing resolved it -when I changed tyre rolling radius dramatically. Switching between similar/same sized tyres never bothered it in my experience.

Basically, like many other things I think - once upon a time someone on a forum mentioned that the paddle thing does some kind of super SMG reset / reinitialisation / whatever you want to call it - and it became 'fact'

That's what I was trying to say SOAB, but I was trying to be a bit more diplomatic about it ! Another internet forum myth methinks

To clear this up :

"After changing a tyre or wheel and after fitting or removing snow chains, the slip monitoring feature of the SMG Drivelogic must be allowed to to adjust to the modified status.

Initialise the system again:

1. On a straight road, driving at a speed of more than 30 km.h (20mph), move the selector lever tot the neutral position N
2. Pull both shift paddles for approx. 2 seconds.

If you do not perform the initialising routine, the system will graduallly learn the modified status automatically, as you drive. You will notice this by the clutch being breifly disengaged and engaged"


So it is a reset, although not as we know it

Is there any benefit whatsoever in doing this IF you have NOT fitted snowchains or changed a wheel???

Nope

Although there's plenty who've claimed they can detect a huge improvement, but that's just Jedi mind tricks

When i did this i didnt put the car in neutral - it was in S5 and i was doing a steady 50mph, pulled both paddles in for about 5 secs and the car sort of hesitated very slightly. To be honest car felt a little more sluggish on the changes - but im hoping that was my imagination!!

You do have to be in neutral so you won't have done anything .. other than change gear up or down or not at all depending on your timing when pulling both paddles

If you're unsure the procedure is in the M3 handbook in the 'changing tyres' section
