MG4 Undertray dip/bulge

[Rip Van]

Just had my MG4 SE delivered today!

Had a look underneath the car and I'm guessing this is the dreaded undertray bulge?

That's a shocker, PDI?

It looks like the centre bolt has come out of its hole.

Good point. Some owners have reported loose bolts, so it might be that rather than warping.

Both, I'd wager.

Mines due to be replaced on 3rd Oct .
I'll report once it's been done

They somehow missed this during PDI. Apparently the dealer who supplied it is not aware of any potential undertray issues with MG4s! They've suggested I take it to my local dealer as the dealer who it was supplied from is all the way up in Birmingham, the joys of salary sacrifice leasing!

Good point. Some owners have reported loose bolts, so it might be that rather than warping.

Yes I suspect that too, hopefully local dealer can sort it out.

I wasn't aware of this issue until today, but after checking, I discovered that mine has little bulge and is cracked near the bolt

What sticks out is soft fabric. I pushed it back into place

I've got a 2 year service (with hopefully no updates* & a dripping undertray) tomorrow @ Paul Rigby (the local MG dealership to MG parts warehouse 'home' in Birmingham/Reddich), I'll report back as to whether I get a fix? or not, and more importantly whether my LKA stays off at all times.

* my LKA blissfully defaults to OFF on pressing the brake pedal when I select drive to move off.

You'll have to let us know how the Redditch dealer is, it's near my family so it's a possibility for me to use

Will give the feedback

I am booked in for the 13th of November to get mine done. I have also asked them to look at the LKA turning itself back on. I am not entirely sure what the trigger is.

 

[NLMGSAN]

Did you check the light switching on and off, triggering LKA? There is a video about this.

It doesn't seem to be the lights and in fact today I was thinking it had stopped and then as I was half a mile from home it changed again. I think it may be the day/night mode as I was driving under the canopy of trees so I have switched it to dark mode to see if that is better. I'll go do some more reading in the thread(s) on this.

Hmmm .. actually, this is what I meant. Check the youtube clip mg4 lka bug & hotfix: Clip

Yeah but if you look carefully, the LKA icon on the driver screen is amber:
I think the bug simply shows the switch as ‘on’ but the LKA itself is still disabled.

I think the amber light means "ready"
If it's white it's off .As per the acc

 

[NLMGSAN]

Not on mine. If I toggle lka to off, it is amber. If I leave lka on on but do not use LDA or ELK (mine is a Trophy), it also is Amber.
It turns white if the system is temporary unavailable(standby).

Check page 44 of the manual

 

[WonkoTheSaneUK]

On a Trophy, LKA is

• Amber when off
• White when on (but you're doing less than 40mph)
• Green when active (and about to try and kill you)

 

[haloweenhamster]

What about grey? Mine seems to flick between white & grey

Gandalf, is undecisive?

You mean the lane markers? Never saw that symbol in grey.
