Is the HV isolation fault occurs, it's likely water got into the HV circuit, it could have been days before. Did a technician with the appropriate software reset the faults? The system fault (which is the major one) often includes HV isolation. Autohold fail, Hill Hold unavailable and a result...

All those faults are caused by HV isolation, I had it twice in 3 years, put a 1kW fan heater under the motor for a couple of hours (you may need to remove the undertray) and then call your breakdown organisation/ local diagnostic equipped mechanic, to reset the safety faults (HV isolation) were...

Yes, you can. After a few drives it "learns" the new range from the increased capacity.

I think most problems on MGEVs are manufacturers' faults, apart from the ones which are design faults!! I think the key issue in these stories is some kind of physical impact to the battery, in all MGEVs it's very low down, I've grounded on a few occaisions, usually when turning/ pulling on a...

That's an expensive one!! I bought one 2m ago for £1k Try this one https://www.ebay.co.uk/itm/365637510540 Yes, I know that's just a 52.5 But you can get 61.1 for less than that. I have a working battery box with connector you can have for £250

The connectors are pretty waterproof as well!

Hi there, I have had a similar problem with my MG5 but not driving through water, when driven on the motorway in rain when there's a lot of spray there was enough moisture got into the "sealed" motor unit to also make it HV disconnect. As I'm a highly experienced electronics engineer and...

Hi Arfur, I can sell you a LR battery for £1500! just need a mechanic with a pallet truck to fit it. I can get 230miles from a MG5 SR in summer, I think 280 is achievable with the 61.1kWh battery

Hi, what "modifications" are required to fit a Chevrolet CRUZE towbar to an MG5, because they are 1. Heavy duty, allowing 1200kg towing load, and 2. cheaper and widely available. Thanks!

It weighs 30kg? What's the trailer loading limit? (towed weight, nose weight) Having removed the front bumper (a few times!) and replaced the front crash beam, I can say thats easy once the bumper's off, front on an MG5 is 4x 18mm hex bolts each side. If you're talking about fitting a towbar...

I would say if you're not going great distances, it's not going to effect the handling of a 1.7t+ car that much, it doesn't exceed the hitch loading by much. you could put then on a roof carrier, then a short ladder will come in useful!

Hi Lloyd, It actually fits quite well with some research that I'm doing, about a Etrailer, e.g. a powered one. you will notice a marked decrease in range, due to extra rolling resistance and drag. I'd be interested to know how much (in %, and effect on normally acheive miles/kWh) that you...

Hi pears, If a FWD car will tow it, then an EV will. They have the advantage of being heavy, and very low centre of Gravity which increase grip/ traction on a slope/ tilt. I guess you have a towbar for it already? I'm actually working on a new project ATM, developing an EV powered trailer, which...

I achieved 210.6 miles with 9% remaining yesterday, driving from Torquay via the Mendip hills and Wells to London. 4.8miles/kWh. In a standard range MG5 quite heavily loaded. Tyres at 2.6 bar front 2.2 rear. I haven't fitted my A rated front tires yet but they will probably improve efficiency to...

On a cold morning, put a fan heater in front of the drivers' seat, for 20min, you won't need to use the heater for 30min at least! (and wear a coat)

A lorry can't brake faster than I can! so if you have slower reactions, just follow a bit further back! BTW, you don't have to be too close to the lorry, if it's high, it leaves a long slipstream behind it. Have the MG in Volts-Amps-RPM screen (pity it doesn't have mph in the spare quarter!) and...

My best efficiency on a SR MG5 was 5.3miles/kWh, over 111.4miles. Driving around 50mph behind lorries! Here's a picture for those who won't believe it. Mostly on M1. At that rate my range would be 301miles! (on a SR)

Tighten the valve, using a valve tool. they are on some metal dust caps. if it doesn't stop going down, you probably have a puncture (nail or screw, still in the tyre...)

Previous post editted. I posted it in another thread 🧵

That is atrocious efficiency, I did 4.2 on a trip from SW London to Basingstoke today and I was doing 60-70 mph. In an MG5. On the way back, it was more like 80-90! And that was about 3.3. you should really try to slipstream more lorries! 😉
