35i or 35is?

[Obs-Com]

Regardless of what mode you put the DCT box in the car will change down if you put your foot to the floor unless the gear down would result in it over revving.

Depending on where in the rev range you are it could result in a double gear down change.

It's only the newer DCT box that allows you full manual control

Foot flat to the floor in DTC manual does NOT drop my 35iS to the lowest possible gear. I have to press the down paddle in with my foot beyond the kick down point for that.

Nor mine. Must be come with the VO spec!!

Sorry but I think you are wrong on the Z4.

Next time you are in it put it into Drive and then push the lever to the left. Set off and change into 3rd at about 30 mph and then put your foot down hard to the floor and she will kick down into 2nd or possibly 1st or try 4th and do the same thing.

If half way round a long bend and you intend on powering out of the corner you need to feather the throttle in the 35is or it may down change upsetting the rear end.

Ok. Mines only a few months old, i assumed all did this.

I regularly accelerate down the slip road in 7th gear from about 40mph, foot pinned. At the correct point I tap the left paddle which immediately dumps me into the lowest possible gear. So don't tell me I'm wrong because this is how I drive my car.

Mine is 9 months old.

sport plus
stick to the left
manual mode?

 

[techathy]

I'm using comfort & DTC manual mode.

 

[Zed Five]

I should probably shut up, but if mine in manual and stick left it does what i want, its basically manual. It i dont change up itll rev like mad, likewise i can change down 1,2,3 gears if i wish. I cant say its ever left lacking.

 

[techathy]

I agree. It has to be with the gear lever over to the left & in manual mode. If I'm in over-ride mode (stick in the normal D position) and click through into kick down then it drops to the lowest possible gear.

Yeah that proper manual mode. If you use 'manual' via the paddles without shifting the selector to the left then it will basically behave like an auto and revert back to auto mode and have kick down. If you want a bit more power like a kick down when in proper manual mode you've got to shift it down. The only auto thing it will do in manual is rev up to the read line and then change up. It will not allow you to over rev the engine or keep it at the line whilst in motion. Likewise it will shift it down if the revs drop too low. So you can use it like a manual but still protect the engine.

 

[Z4M-2006]

Same as mine...

I have never had the car kick down when in manual..Its basically manual shift...

Although i will try and provoke it to do that now its been mentioned..


Then again,im probably using the correct gear for what im doing...

What is DTC please?

After driving the 35is in every possible mode on Monday and locking the vehicle into manual (pushing the lever over to the left and then changing up a gear or two) if I put my foot to the floor and beyond the "normal" kick down point the box changed down either once or twice.

Now unles they have changed the box on the 65 model year vehicles you cannot lock it into a gear.

I suggest you have a go and report back please but this is my experience on a lengthy drive.

The sales person also said the new box (not available on the Z4) did have the option I was after but not the Z4.

Unless we are talking about different things can someone technical help out?

So it changes up at the rev limiter? So why do you think it won't change down if you kick down using the accelerator? I guess if you gradually put the accelerator down it would not but if you floor it suddenly it will change down - try it I will wager £5 with you.

DCT manual sorry (I find it extremely difficult to see transposed letters or numbers). Mine is a MY15 car and certainly does not kick down straight away in any mode with the leaver pushed to the left & the gear indicator showing M. I have to press the left paddle then it drops to the lowest possible gear. I've driven my car for 5700 miles & can tell you it does not kick down in DCT manual until I tap the left paddle. Also I can tell you that in comfort mode the last 20% of the throttle motion to kick down does absolutely nothing & in sport it's the last 40%.

 

[Z4M-2006]

Perhaps its a failsafe for engine damage limitation ??

i have never experienced it.....

In what gear at what speed and at what rpm are you flooring the throttle ?

No worries, thought I was missing something but yes it's easy to transpose letters especially when predictive text kicks in lol.

So to the kickdown or not issue. I will wager a £5 that if you follow what I have said earlier i.e. set off and put the lever in manual mode in comfort or sport or sport plus by pushing the lever to the left. Change up a gear or 2 via the lever but keeping the revs low, then put both hands on the wheel not touching the paddles and put your foot to the floor as if trying to get the car to downshift the same as you would to use the kickdown as if in auto mode, and she will kick down.

Please try it and let me know or I am going round the twist having spend over half an hour specifically trying to get the car not to do this.

So....

What speed,what gear and what revs are your flooring the throttle to get the car to do this ?

 

[Japseroony]

As previously said, 3rd or 4th when in manual drive mode at a low Rev level say about 2000 to 2500 revs.

Try it in a higher gear and it will possibly change down to a lower gear such as 3rd or 2nd from 5th etc.

Your revs are too low for the gear you're in, it's just stopping you from stalling.

Will try that...

It's something I have never come across..

If it does I dare say it's some kind of torque limit failsafe thing...
High gear, low revs and flooring the throttle isn't really too good for the driveline, especially with the buckets of torque..
