E60 M5 'driving style detune' reset?

[simonpa]

Been reading Eddie's fantastic buying guide sticky again and had a question regarding the 'detune' the car performs to suit the owner's driving style.

Can this be reset, by disconnecting the battery, for example?

I have an occasional hesitation, that could be down to this, or possible fuel/pump pressure, when pushing on.

TIA - Simon

Many thanks for that comprehensive answer, JC - I have a lot to learn!

I've only had the car a couple of weeks and will go through the service history again to check when plugs, etc. were last done.
The throttle actuator was changed some time back, so a check the TB connections are secure is sound.

Cleaning and refixing MAFs, checking the plugs and changing filters are a good idea. I'll do that too.

Is resetting the DME adaptations afterwards something that can be done simply, or will it need to be done by a specialist?

Thanks again,

Simon

Just to make sure - are you talking about the gearbox or the car in general? If it's the gearbox being sluggish in D mode then the solution is easy - drive in S5 mode all the time!

I'm talking about the engine output specifically.

I've noticed how the gearbox changes in D can change significantly, depending on how you drive - use kickdown a bit and it will hold changes longer for a while, even if in D1 or 2.
