    K&N panel filter (engine)

    Hi, what do you think about K&N air filters or Pipercross foam filters? Would you consider trying one if you found a compatible option for the MG3 Hybrid? Because I might have found the right sized filter.

    New ECU software

    Hi, The MG dealer here in Slovakia offered me the option to update the vehicle software (ECU) on my MG3 Hybrid+ Exclusive, and I’m not sure whether to go for it. It’s completely voluntary. I bought the car in September 2024. I’m a bit concerned that the update might change the car’s hybrid...

    iPhone with Carplay mic issue

    Had my MG3 10 days now and it's great. I'm trying to get to grips with Carplay (which I've never had before, except on a couple of rental cars when I didn't try making phone calls with it) and my iPhone 11. It connects ok (with a cable) and I can make and receive phone calls. But whilst I can...

    Anti collision

    Hi all, How do I know if the anti collision is working correctly ? I try driving up to the rear of the cars infront, without actually hitting them and if I don't slam on the brakes I would go into them, but the car doesn't do anything. How does it actually work ?

    Set of temporary yellow warning lights??

    Yesterday I pressed the main power button while forgetting to press the brake pedal. The button's led turned orange instead of green, and then I remembered I have to also press the brake pedal, so I did it again. Then something strange happened: The steering wheel moved a little with a quiet...

    Radio won’t play when connected to CarPlay

    Does anyone else have this problem? I can listen to the radio no problem when my Apple CarPlay is not connected. But as soon as it connects the radio just won’t play. Sometimes it looks like it is playing but there’s no sound and other times it just does nothing when you press play. Anyone know...

    Software version Mg3 Hybrid+

    Hey lads, just wanted to compare software versions on the MG3 Hybrid+. Some of my car’s parts are stamped April 2025, and I took delivery in August 2025, but my infotainment system shows software version: October 2024. I’m curious what versions other owners have by default from factory...

    Screen not returning to Apple CarPlay after reverse/360° camera

    Quick Q for any iPhone users here! I've seen a strange behavior/difference on how the infotainment system works depending on OS: Android Auto --> The car will automatically return to the Android Auto view after the reverse or the 360° camera is turned off Apple CarPlay --> The car will show...

    HEV/EV energy flow

    Hello. Over the last couple of days, I've noticed that when the energy flow is shown coming from the battery in the back to power the car, its staying in HEV mode and not switching to EV. Is this normal? I've been doing city driving, so no more than 30mph. Haven't noticed it doing this before. I...

    Old friend returns!!!

    A year later after umpteen visits to my dealer resulting eventually in a replacement EGR valve. The 'Engine emissions fault' light is back on!!! I suppose i should be grateful as this time for a few seconds i had a red warning light (an unintelligible symbol), which i think I'm right in saying...

    Intermittent radio

    Has anyone experienced problems, with the radio, on an mg3 hybrid+? I can drive my car listening to the radio, park up, repower but not get any radio. It’s totally random.

    Tyre Pressure

    I am beginning to hate this car because I find the manual impossible to follow and think it's too clever for its own good - manual switches are so much more intuitive than touch screen. Rant over. My problem is that 2 yellow signs were illuminated and I had no idea what they meant. I eventually...
  15. Bikes pulling out from side roads..... Collision warning.

    I had a new experience yesterday. I was driving along a main road when a pushbike pulled out reasonably quickly from a side road and eased into the traffic flow in front of me. Although he didn't pull directly in front of me, the car detected him coming in from the side (about 10m in front) and...

    Would I regret getting an SE?

    I have driven an MG3 Hybrid Trophy a few times as we have one near us on the Zipcar carshare and I absolutely love it. I would like one for myself, but I don't really fancy signing up to finance, especially with the 6.9APR. I have found an SE model on a lease with AA for £142 a month with a...

    70MAI Dash Cam A810

    Hi, today I installed a UP03 wiring kit on my MG3 hybrid. It's not the original. I thought I was buying it, but when it arrived, I realized it wasn't. It's for a 70mai A810 camera. I plugged the ACC+ into fuse 21 and the ACC into 29. The camera works 24 hours a day, but it gets really hot...

    Steering wheel position

    I park my mg3 hybrid+ in my garage, but due to space limitation, and making it easier to get out of the car, I have to put a degree of wheel lock on just before final position. However, when I get back in to the car I get a message “return steering wheel to neutral position”. Surely if I leave...

    Just back from a Euro Trip in the MG3 Hybrid+

    Well, I have had my MG3 since March 1st and up to last Friday I had done 600 miles, yes I know not a lot, but having four cars, it means they all get lower annual mileages. Anyway, our neighbour was going on a cruise from Southampton so we offered to take her down there, from near Lincoln, we...
