f10 m5 rolls forward

[forest172]

When parking up the m5 in reverse gear. If the ground is uphill I find if you press the brake after going backwards then when you release the brake to press the accelerator again the car can roll forward. And feathering the accelerator in reverse is all or nothing. This also applies when doing the same in first gear.

Anybody else find manuvering difficult?

Try holding down the down paddle on the left hand side, I recall on the E46 M3 if you did that it activated a bite point for a few seconds.

Do you have hill assist on the car? this usually cuts in to stop this happening. You have to give the brake a bit of push to build the pressure in the system for it to work properly.

I haven't noticed this but the parking up in reverse & then switching the car off in gear is taking some getting used to. So used to having a physical Park selection point.

Have noticed that the car doesn't creep on idle & needs a dab of throttle to get moving when manoeuvring which is also taking a bit of getting used to. Have always crept out of the garage in gear but now have to make an effort to accelerate to get out.

When parking up by just switching the engine off some slight movement can occur however you can apply the hand brake once the engine is off which stops that.
The gearbox is designed to creep slowly in traffic by a quick dab on the throttle, you only have 2 seconds to apply throttle if in gear on a gradient and lift off the brake peddle, it still a manual box not full automatic.

I thought it was a proper DCT - not an SMG as used in the E6x?

M-DCT is not an Auto.
SMG was crap.

Me too, but that would explain the lack of a proper Park & the no creep in gear as i recall that being the case with my E60 M5.

Not an issue but taking some getting used to as the A8 was a full blown Auto & the GT-R before a full blown DCT.

[HoHoHo]

Interesting.

My 335i was DCT and that crept - but also had park!

[forest172]

I think the major bug bear is that when reversing the car can move back quicker than you expect, more so when reversing up a slight gradient, then it can roll forward which is a pain. Moving forward is easier, it just doesn`t seem to like reverse gear

Also how do folks select park, just pull up the P brake when stationary and in D, or select reverse then pull up P??

[HoHoHo]

Don't you have to push the gear lever left and then up?

I need to find a solution to this, and generally low speed maneuvering with DCT.

I've not tried it yet, but the only way of maintaining any fine control I can think of is to apply the brake with your left foot while using your right foot on the accelerator. The brake pedal can then be opperated in a similar way to the clutch in a fully manual car, gradually release it and cause the clutch to slip. Obviously if you did this a lot or applied the acceleartor too much it would burn out the clutch, but it's no different to abusing a clutch with a normal manual gearbox ..... is it?

Is it that bad?

Can't say I noticed on the test drive.

[RichardM5]

Try driving a manual car whilst imagining the clutch and hand brake are an on/off switch, that's pretty much it.

[HoHoHo]

Ah, what does the general M5 fraternity think?

I was told when i collected the car to put the car into reverse (or leave in reverse depending on the manoeuvre that got you to the position you wish to park in), engage the handbrake & then switch the car off at which point the R turns to a P. I do find this an odd way of parking/selecting park but it appears to be correct.

I think that's what I've been told (and describe earlier, clearly badly) albeit I've not hot mine to try yet.

NO 335i Ever had DCT sorry.

I have never selected "Park ever" on My LCI. Just turned the engine off.

Apart from the ones which did have it, including this car which Evo tested in 2010: http://www.evo.co.uk/carreviews/evocarreviews/2510...
