Default Any B owners with CVT - can you help?

I have just purchased a B180 CDI 2008 (facelift) with the CVT gearbox.

I understand it is a 7 speed transmission but when entering manual mode I can only choose 1 to 5 - there is no 6 or 7

At 60mph it is doing just under 2000 rpm which feels about right so not sure whether this is correct.

Can any other B owners let me know if they can choose all 7 gears in manual mode or just 5 like mine

Thanks

CVT driven vehicles dont have individual gears, it is a continious drive system. There may be a manual selection which will imitate gear speeds.
Your mph to revs sounds about right.
You should read up on cvt 'gearboxes' as they can be quirky.

Yes, I realise that they are 'virtual' gears rather than specific gear sets - however some B owners are reporting that when they select the manual mode, the display allows them to select any of the 7 virtual gears.

Instead, mine only allows 5 to be selected and yet the car seems to drive OK

I was trying to find another owner of a 2008 B with the CVT to see if it was programmed that way or whether I might be developing a fault of some kind.

It should go 1-6 in manual mode and then when you tip it to 7 it should display D.

That's weird - mine goes 1-5 and even if you push it to + again it stays at 5

If you push it to + and hold it there then it goes back to D

Are you checking yours on a B or another model?

Thanks!

I dont own a B class, but i have driven probably 2000 over the years! The A class CVT is exactly the same too!

I would suggest though it is user error....

If you arent going fast enough for it to select 6th, then the ECU wont allow it, so a double tap of the tip tronic is sending it back to normal D mode. Hence it seems to go from 5 to D.

For example, if you were driving a manual car at 30 mph, you wouldn't try and select 6th, the car would jerk and hunt as the speed and torque is too low. Same principle applies. The ECU knows your speed and engine revs are too low for your desired selection, so it wont allow you to shift there. The same way as it wont let you downshift beyond a rev range that it will bounce off the limiter.

Try selecting 6th at 60mph and see what happens.

That makes sense - I'll check again but I believe I tried it at around 60mph - but I will try again later - thanks.

Naraic - seriously!! - 1-5 are manual gears and D is automatic mode - doh! But I assume it was said jokingly

wifes 169 does show 7 gears but if I remember correctly it didn't show until I was up around 70 (ish), going up through the gears 1-7 as Steve suggested if it's not going quick enough it just drops back to D

6 & 7 I believe are more overdrive gears than anything

Trying to be helpful. You'll fit in well here. I don't know anything about your mickey mouse gearbox.

In my car D means I have 7 gears...when I nudge to the left it drops to 6th , then 5th and so on. What happens when you move to - (as opposed to +)?

But hey, you know best. I presume you have a user hand book...read it. You may find you are missing 6th.
