Forward creep, or lack of

[Ben23]

Hi all. Prospective AH10 owner here, I just test-drove one for the first time and I am a little bit in love.

Question though. I've not driven many automatics but all those that I have, when in D, creep forward (at least on a flat road) as soon as you let off the brake. This one didn't - is that normal or could it indicate a problem? It was a 2.4l, non-hybrid. Seemed to drive perfectly well other than that.

 

Cheers

I’ve got an AH10, I’ll get back to you tomorrow after a check on the flat.
If I’m pulling away from stopped I usually have my (left) foot on the brake, select drive, accelerate away as I release brake.

Yep. All creep forward. Stuck brakes? Etc Etc Etc

Is the AH10 2.4 a CVT? CVTs don't naturally creep. It is torque converter automatics that creep on tick over. 

 

I know on the hybrid with eCVT that creep has been artificially added to make it creep when in drive. I'd imagine they did the same on the non hybrid for same reason of giving it the traditional auto driving experience.

Ah yes of course!

Well then, its not impossible I'm wrong! But, into the mix, the DSG gearbox cars we've hired on holiday the last 2 years both drove like a "normal auto", and they aren't. 

I'll be watching for @Clutha response after checking on the actual vehicle!! As that's the ultimate test report!

Or anyone else with the correct model of course!

We learn something new everyday!

 

About 15 years ago I did a supercar driving experience as a present, and a Ferrari had a gearbox that didn't creep, but was therefore very jerky on take off. So maybe it's "engineered in" for the masses?

From what I've read, all non-hybrid AH10s use a standard 4- or 5-speed (depending on engine size) non-CVT.

I appreciate it, thanks.

I've never heard of doing that routinely. Doesn't it risk wearing your brakes faster as you're effectively accelerating before the brakes have fully released?

Probably I’ve never noticed creep due to changing to neutral when stopped & idling temporarily on the level.

Drummed into us in my youth to save fuel in a fluid flywheel auto box.

In our Alfie you can hear a slight change (drop) in idling revs going from N to D

I was very surprised after getting van & researching do’s & don’ts on line re auto boxes to read advice to stay in D, I never do when idling.

It’s a bit like clutch & throttle balance on manual boxes.

TBH as soon vans in D and I’m pressing accelerator we’re off. For the split second between releasing brake and moving of I’ve never had the van roll back if the slope is mild.

I did go out practicing a lot on proper steep hill starts to get used to the ‘foot parking brake’

Spent a lot of time during HGV training doing this as instructor insisted we move off in 2nd gear 🤔

Creep? It was like an F1 car 😂

I went round the (quiet) block in ‘D’ without touching the accelerator including slight inclines, not shuddering from engine, all very smooth.

I'm retired so no rush hour driving, just clear roads where I’m going.

I  think there are settings to be looked at on yours.

(Most) Automatics are designed to be stall-proof.

Just to add that my 2005 facelift 10 creeps forward on the flat also - not fast, not quite walking speed if I were to guess. Obviously when in D and with the brake(s) off.

 

From my limited knowledge of automatics (AA Book of the Car) it could be due to a high idle speed and / or the fluid flywheel being too full or having it's fluid not fluid enough (or too much, I guess either would do the same).

 

I would say it's normal, but you might need to consider the ambient temperature as that may affect performance, both of the auto-box and the engine when on 'choke' after starting as mine revs high then anyway (though I am awaiting a replacement MAF sensor as I am getting the P0171 lean fuel on bank 1 message and a spray with cleaner hasn't made any difference).

Thanks guys. I test-drove a different one today and that crept as I expected, so I guess it was something amiss with the other one. Today's is the one I want to buy anyway

Great!

Definitely something amiss with the one you described.

I was out in ours today re checking settings, in D or R engine sits at 1000rpm and on the flat van moves at walking speed.

In neutral engine is at 600rpm
