    Has anyone had this problem on the app?

    It has always been that way for me - refresh and see what happens. Sometimes the car just falls asleep and won’t respond at all. Very annoying but usually unlocking the car and relocking, all is well again.

    EV tariff increases the daily tariff !

    This !!! It really helped getting an EV in overall cost in an all electric house and the modern storage heaters also great. Car, dishwasher, washing machine, immersion heater, storage heaters. I’d be pulling about 70amps for a decent length of time. The only one I’d really avoid if you aren’t...

    Mg4 corrosion resistance.

    There is a cross member under the radiator at the front (behind the standard grill on my se sr) that is starting to look a bit ropey on a sunny day - well surface rust. It’ll need tidying up at some point I’m sure.

    Car wont lock or unlock with door handle buttons

    I had button failure on passenger door of all ones. Symptom was more that the button no longer clicked at all rather than clicking and not working. I’d lay a few £ that underneath the plastic is a micro switch, the same as a cheap mouse. It was replaced under warranty with a completely new...

    MG4 Charging power 0.0kW

    I don’t have an Indra or octopus but setting slots on the car and my charger was a no no, I just had to let the charger do its thing with no schedules set on the car. Also I had very irritating issues with my scheduled charging failing when there was power line networking kit in my house. I...

    Coding of 2nd hand modules (question for the techs )

    Most modern cars have moved to this. It is to prevent theft, make parts difficult to move on and also a nice money maker being able to only fit virgin parts. It isn’t really new - BMW based stuff from the late 90s was a pain having to match all modules together and needing the ability to...

    Questions about buying a used MG4 SE

    I have a mega first off the boat phase 1 - tinted rear windows. Software updates yes BUT they are applied with dealer tools and software - you’ll be lucky to get many anyway if things work unless you buy the tools. OPD is not on phase 1 and apparently never will be. Can’t really see it other...

    Tyre Pressure Monitoring System Failure MG4

    It requires extra equipment to do that hence costs more. The way they do it is fit a transducer in 3 wheel wells (you fire a few kHz signal maybe 100khz can’t remember into the TPMS sensor and it replies with its pressure, serial number etc on the frequency of the central locking). It can...

    Tyre Pressure Monitoring System Failure MG4

    The sensors have a battery in them (usually a large button battery potted into the sensor). When the battery gets low or dies - the sensor is toast as you can’t replace the battery. They transmit data on the same frequency as the remote central locking. The car knows where each sensor is as the...

    Surprisingly short battery balancing period (still)

    I haven’t had too much chance to do experiments (don’t have a home charger anymore long story) but my early SE SR after updating every module myself including the BMS spent an eternity balancing the battery 2+ hours then settled. Using work chargers now so can’t really see but it was interesting...

    Diagnostic VDI, VNCI, MDI with MG4

    There was a BMS update and it was one of the smaller updates then again my car was one of the very first in the UK (it has the wrong back windows). Pretty sure you will … that’s what does the lane assist and everything behind the rear view mirror unless you mean it’s been removed.

    Diagnostic VDI, VNCI, MDI with MG4

    Links are in the 1st post with guides. You’ll need a usb stick and the files off here for the infotainment update (which is part related to the HVAC). It’s not really hard to use BUT it gets itself in a knot failing to update modules so will often take multiple goes/disconnecting battery etc and...

    Diagnostic VDI, VNCI, MDI with MG4

    You can get downloading the software now - it’s rather large. Only other bits I can suggest are have a laptop with a good amount of grunt (the software is oddly bulky), update the firmware on the VCI, have a 12V battery charger on the car and if doing software updates buy a whole day; very long...

    Diagnostic VDI, VNCI, MDI with MG4

    Read through this thread thoroughly. It is all downloaded via MG which eats into your paid for time. Some kind member has archived it so you can get it all ready for when you pay. Links and guides all early on in the first posts.

    Water in boot lid

    4 attempts at 2 different dealers with the final visit being a week. Exactly the same situation. There is a service bulletin to apply sealant to a panel (didn’t fix it). There were many many clips replaced getting to things but the leak was fixed. 1st gen SE

    So count me in for the 12 volt discharged battery problem

    I believe there was a service campaign early on. The amount of updates on my 1st gen was basically every module. Also… the battery supplied is trash, there were stories of them barely lasting a year.

    Diagnostic VDI, VNCI, MDI with MG4

    Modules that fail, reprogramme individually as replacements - different tab to the one touch update. To get it to work there may be battery disconnects needed and as for the park thing. Mine had similar but updating more modules and doing that final procedure it warns you about (parking on...

    First service

    It’s all software. Not sure what versions etc you’d have but I had an early SE and updated everything as per the guides (and buying the kit on here). The heater behaves much better, lane kill much better even the mileage I get seems improved (I think I can stuff more in the battery and it tends...

    iSmart Update to 3.0

    Can’t get into mine - looks like the iOS update has happened but can’t log in. Says email, telephone not registered. Is it down by chance ?

    Diagnostic VDI, VNCI, MDI with MG4

    Make sure you are applying the correct files for the head unit on usb. Run the auto update in sips “update all” as I recall. That lists every module with firmware and calibration vs what’s latest on the servers - you want green ticks on all of them (this is a hellish process) and if any fail -...
