Throttle/Automatic Transmission Reset

Hi Guys,

I've been experiencing a few throttle and gearbox response issues with my zed of late. I have a feeling the previous owner may not have driven it with quite as much vigour as I like to :driving:

I have heard about Throttle and Transmission reset procedures for a few BMW's including the E85 and I was just wondering if anybody has done this or have any experience of doing this on the E89? :thumbsup:
 
There are write ups everywhere (ignition on, don’t start, full throttle for 30 secs, ignition off, release pedal, wait 2 mins and restart) but I’ve tried it and it’s a placebo imo, it’s never made any notable difference.

How do I know? Because I now have MHD and other tools that allow a proper reset at a module level. That does make a vast difference.
 
Thanks, I've read the write up's and was considering trying it out, but given your feedback sounds like it may not be worth with time. Just googled that MHD tool you mention and it looks great! (shame I don't have an N54/N55)

Do you know if such a thing/tool which allows for module reset exists for N20 engine (2.8i)? :thumbsup:
 
I think the only tool that can do a proper transmission adaptation reset is INPA or ISTA.

There is an option in MHD for it but I'm not sure what it does exactly. I know it certainly doesn't reset the clutch wear adaptations in the DCT box as this requires a very detailed drive cycle and procedure to re-adapt.

Yes MHD is throttle reset only. DCT adaptation is as you say, a bit more involved.
