MG4 64 with a problem (reverse creep)

[David Wennerbom]

Hi I'm from Australia, Sydney NSW. Really up near Newcastle. 70 or so kms north of Sydney. I have a problem that seems to have stumped MG dealers around here. I traded my ZS EV for MG4 64 after owning it for 3yrs. Both vehicles I can't fault except for minor things. Range wasn't good in the ZS, 267km. MG4 530km. We peddle around a bit.
When I'm driving down hill towards a stop sign on a T intersection. Apply the brakes and stop. I release the foot brake and the car will reverse back up the hill I've just come down. If I'm going up a hill or on a flat and stop the car wants to travel forward.
Forward isn't a problem because I can leave the space, but backwards and the vehicle behind me gets too close I could back into him. Just that it is annoying. Auto-hold should engage but doesn't. I could click the handbrake, which I do but shouldn't have to. Anyone with suggestions, I would appreciate useful information. I'm David Wennerbom and do quite a few roadtrips if anyone is interested in hearing about them. I also help an organisation out here doing EV Drive Day Weekends. I've had my MG4 now for about a year and a half and am about to leave on a tour down the Great Ocean Road on the south western coast of Victoria and returning home via the outback of NSW. Test the MG4 out on a bit of rough country, long runs between towns and cities. Grab a couple of rides on old paddle riverboats on our longest rivers.

Hi David,
I activate the auto-hold by pressing the brake with an extra push.
You can tell when you've given it enough extra push by looking at the main screen. Below the speed, in between the "READY" sign and the Battery SoC reading you'll see an 'A' in white when you've come to a stop. Give the brake an extra push and it will turn green and you'll be stopped without having to keep your foot on the brake.
I used to use the OPD mode to get a similar effect, but you need to manually enable OPD every time you set off.
The brake push method works more conveniently for me.

After you put your car into Ready Mode check that Autohold has been set by looking at the Car/Safety page. On that page you can power down the car, then when you press the brake to put it into Ready Mode you should see the autohold button move across to the right and turn blue.

Is this the same problem discussed here:

Thread 'OPD, car rolls backwards when stopping on downhill slopes (merged thread)' OPD, car rolls backwards when stopping on downhill slopes (merged thread)
There is a good video of it at post 20.

After a recent software update in the UK (SC077 ?) people have commented that OPD behaviour changed at the same time. The car may come to stop more smoothly over the last few metres and the strength of regen under OPD has been reduced.

Both of these may be to do with addressing the reversing problem. This is just supposition though as I'm sure MG would never admit publicly that the problem even exists.

I'm not sure this has anything to do with what the OP is saying, but just an observation i've had on my car. If the brakes are pressed twice (i.e. brake to a stop then lift foot off brake partly and then press down again) it seems to cancel the autohold. For some reason I seem to come to a stop let go of the pedal pressure then press down again, not sure why i do this, but this behaviour wasn't how my previous Ioniq worked.

Maybe this Jerry Pan tutorial video will help to determine if things are working as they should be

Thankyou Jamesrr and to the others for coming to my rescue. I also notice you are from Australia. I didn't have to go to GB for answers, anyway thanks for responding David Wennerbom

No, but they're good for out of hours support
