MG hybrid and electric car service and repairs
MG has become one of the most widespread affordable electric car brands. We work on the whole range: the ZS EV, MG4, MG5, the HS plug-in hybrid and the MG3 Hybrid+.
Why take your MG to a specialist
Electrified MG cars aren’t repaired like a petrol car. Without the right equipment and high-voltage experience, the diagnosis stays half done.
- 01
The 12 V battery, a common complaint
ZS EV and MG4 owners often report flat 12 V batteries, sometimes because of a load that doesn’t switch off, sometimes a faulty battery. We check both the battery and what is draining it.
- 02
Diagnostics across the whole electrified system
We read the codes from every control unit involved and measure the battery, inverter and charging. We separate a weak module from a flat 12 V battery, a connector or a software fault.
- 03
We repair what is faulty, not the whole assembly
Before any quote for a new MG battery, we test its condition. Where it makes sense, we repair only the confirmed component.
We test first, then suggest
What we do on MG hybrids and EVs
We handle the systems we see most often on electrified cars, from the high-voltage battery to charging, brakes and maintenance.
Many MG owners come to us after the range dropped, after a dashboard message or after a quote for a new battery. We test first and tell you what we confirmed.
- High-voltage battery diagnostics
- Testing every module and the battery’s condition
- The charging system, where relevant
- The 12 V battery and the DC-DC converter
- Regenerative and friction braking
- Battery and inverter cooling
- Maintenance: filters, fluids, tyres
- Software, where we have access for the make
MG models we see often
Every model has its weak points. Here is what we know about the most common ones:
Electric
MG ZS EV și MG4
We test the battery and charging and check why the 12 V battery goes flat.
Electric
MG5
An electric estate often used for long distances. We test the battery and tell you how much real range it has left.
Hybrid
HS PHEV și MG3 Hybrid+
We check the battery, charging on the plug-in and the transitions between the electric motor and the petrol engine.
When to bring your MG in
It makes sense when range drops, charging fails, a warning message appears or another garage lacks the equipment for the electrified side.
Warning light or reduced power
The system is protecting itself. We check the battery, inverter and signals before any expensive part.
Less and less electric range
Battery wear, a weak module or a cooling problem reduces range. The test shows the cause.
Charging from the socket fails
The cause can be the cable, the port, the on-board charger or the station. We separate them by testing, not by replacing parts in turn.
The 12 V battery keeps going flat
Electrified cars charge the 12 V battery from the main battery, through the DC-DC converter. If it keeps going flat, we check the converter, not just the battery.
Frequently asked questions about MG hybrids and EVs
Do you work on MG hybrids and electric cars?+
Yes, on the common electrified MG models. When you book, we confirm from the VIN what we can do on your car.
Can you check the battery’s condition?+
Yes. We test the battery before any replacement quote and tell you what we found and what options you have.
Is it cheaper than a dealer?+
Often, yes, because we repair only what is faulty rather than replacing whole assemblies. If the car is still under the manufacturer’s warranty or has an open recall, we tell you to go to a dealer first, where the fix is free.
How long does it take?+
It varies from case to case: it depends on the model, the fault and the parts. We give you an estimate after talking through the symptoms or after the diagnosis.
