Strange goings on.. (over-revving change in behaviour)

[Pigger1972]

Got my mg3 hybrid in November did the running in bit no excessive revving of engine etc until 900 miles...then just lately I have noticed it's not kicking down and excessively revving when going to overtake..smoother in town too..was wondering if it's had an "over the air update"?? If that's a thing??...anyone else noticed if theirs seems a bit smoother on acceleration??

I don't think there are OTA updates for the MG3

True. But if MG suddenly had thousands of cars to update recall style, that might push them to try at least that one update over the air. What could possibly go wrong?

Presumably, the cars and servers are all ready, just that MG are presumably afraid of a mass bricking, and what that would look like in the tabloids.

But my feeling is that an update would never happen without the owner giving permission. What if someone was ending night shift, and at 3am found that the car had started an update! Please wait... 10%... 12%...

Do any Tesla owners know how Tesla do it? Maybe there is a setting on how and when to perform updates?

I wonder if the 900 miles is significant. If it was 936 miles, then that's 1500km (firmware presumably works internally in km), and that might trigger some different behaviour now that the engine is presumed to be "run in". Or maybe it works on engine run time, which might work out to 900mi for one driver, and 742mi for another.

Can't see anything anywhere that confirms or dismisses it..very secretive about everything to do with the car I'm finding..

That’s strange, mine ran perfectly at first then the over-revving started almost as soon as it was run in. Mine is particularly bad on an incline, up to 5k and vibrating - sounds like a 20 year old diesel! It’s been in four times and they keep saying it’s normal, and are now refusing to look again. I’m so fed up with it that I asked for a trade in fee and they offered 9k less than I paid 6 months ago. I keep hoping for a recall…

I'm not sure that the architecture itself supports OTA updates, if there is even the hardware necessary between the modem that does the app and the whole internal control units. Or the basic SW architecture permitting it; AFAIK, the MG3 (or ZS Hybrid) are not setup for any OTA updates.

Might sort it on first service?? But if you have said they have already had it in then who knows..mine is deffo different now than it used to be..hope you get yours sorted..

I recently bought mg3 hybrid trophy we expeeience high revs when engine transfers over from EV to HEV mode the revs can get high up to 3000 i am sure but car not going faster then after 5sec it stops, it is the electric motor according to Arnold Clarke linwood and according to MG it is a factor of the new 25 models but not the year24 models!!! We had a 24 model for a short time and this issue certainly not there..I cannot accept this is normal, when it shakes to bits get a warranty claim in, told by agent ok to keep driving!

3000 rpm is not high over revving. Mine can go up to 5000 rpm.
Mine has also changed after about 1500kms, I noticed it doing things differently on my normal daily commute to work and back.

 

[KB Hawk]

1500km is about the run in mileage of 900miles, plus i believe the last update on 25 models included this change and MG notified the agents..no mention of this in the sales blurb though!!. As i said 24 model smooth and quiet. Time will tell if all ok!!

I have the 24 model. It had no over revving issue until the engine emissions fault. The dealer did a software update to resolve this and since the over revving has started

Welcome to the over-revving software club!!

 

[KB Hawk]

Apparently the 25 update brings this issue into play like you our 24 model was fine, we now have regular overevving without gaining speed on our new 25 model and according to dealership Maintenance boss MG say that it is normal now, our mpg has gown down from 62/64 mpg to 56.7!!.We reported this within 2days of purchase so if it revs itself to bits it will be a big headache for them!!

How cold is outside and how warm is your cabin heater?

Because the electric motor can't generate enough heat, the gasoline engine stays on continuously, which increases fuel consumption.
