A180 CVT Gearbox

[kwakdonut]

Evening all,

have done this to my C270 and it's great!

What is it you ask?

Resetting the gearbox.

Does anyone know if this can also be done to a 57reg A180 Auto??

Have tried the same key in/foot down/foot up/key off/2 minute wait procedure that works in my 203 but never really noticed a difference.

Anyone help?

Cheers
Tony

Any ideas anyone?

It doesn't work on any car.

The reset?

Seems to work on some but not others - definitely worked on my 270 though. Feels like you've fitted a new gearbox!!

It resets the accelerator pedal memory, not the gearbox.

I believe it resets the throttle position sensor which works with the gearbox and 'learns' your style of driving - that's what I've learned so far anyway!

Surely by its very nature a CVT based system shouldn't have to 'learn' your style of driving?

Am not sure - this is what I'm trying to find out!!

Can you elaborate on the proceedure - I might give that a try on my ML270 to see if it will liven things up a little.

When you say key in - do you turn it on at all and how far?

 

[kwakdonut]

Procedure as follows -

Key in, turn to Position 1 (first 'click'!)
Press accelerator to the floor and hold for a count of five
Release
Turn key back to off position but do not remove
Wait a minimum of two minutes then drive as normal.

I believe that it resets the throttle position sensor and/or the gearbox logic so that it 're-learns' your driving style.

Definitely worked in my 270 - certainly wasn't just placebo effect!! Felt livelier and more responsive - quite sluggish before.

Good luck!
