Short answer: on the all-new MG HS Mk2 (2024–present) — petrol, Hybrid+ and plug-in hybrid — there is no dashboard button-sequence to clear the service reminder. MG’s own handbook states the maintenance display “will be reset by our company Authorised Repairer”, so it is cleared over the OBD-II port — at a dealer, or with an MG-capable service tool. Here is what the reminder means, what the job costs, and the one tyre reset you can do yourself.
What the Service Reminder Means
The HS Mk2 shows a spanner symbol and a countdown to the next scheduled service in the instrument display. It is a maintenance reminder, not a fault. Once the service is done the counter has to be reset, or it keeps showing as due — and on this generation MG did not build in an owner reset sequence.
- A spanner / “service due” symbol that stays on after a service.
- The reminder reappearing at every start because the last service was never reset.
Why There’s No Dashboard Reset
Unlike the smaller MG3, the HS Mk2 has no menu item to long-press. The service interval lives in the vehicle’s control modules and is cleared electronically over the diagnostic port. MG intends this to be done by an Authorised Repairer as part of the service; an independent garage or a home mechanic can do it too, but only with a tool that carries MG service-reset functions.
What the Job Looks Like With a Tool
On a capable tool the path is roughly Diagnosis → Service / Maintenance → Service interval reset. Menu names vary by brand of tool.
- Plug the tool into the OBD-II port (in the driver’s footwell, under the dash).
- Ignition on, engine off, unless the tool prompts otherwise.
- Select the MG service-reset function and follow the on-screen prompts.
- The countdown returns to the full interval once it completes.
The One Reset You Can Do Without a Tool
The HS Mk2’s tyre-pressure relearn needs no tool — it is a passive drive-cycle: set the pressures, park the locked car for 25 minutes, then drive for about 15 minutes above 25 mph (40 km/h) making several turns. See our MG HS tyre-pressure reset guide. That is separate from the service counter, which still needs the tool above.
Garage Cost vs Doing It Yourself
| Option | Typical cost | Notes |
|---|---|---|
| Dealer / independent garage | About a half-hour labour charge — usually done within the service itself | One-off per service. |
| DIY — MG-capable OBD service tool | A low one-off outlay | Pays for itself over a couple of services; also covers other resets. |
| DIY — multi-make diagnostic tablet | A larger one-off outlay | Worth it only if you work on several cars. |
Prices vary by region and year; treat these as a guide, not a fixed quote.
Which kind of tool does this? (When links are live we may earn from qualifying purchases.)
An MG HS service reset needs a tool with MG service functions, not a generic code reader. The classes that do it: an MG-capable app plus a compatible OBD adapter, a service-reset scanner that lists MG, or a multi-make diagnostic tablet. Before buying, confirm the tool explicitly lists MG service-interval reset for 2024-onwards cars — the new HS is recent, so coverage varies.
Check It Worked
- The spanner / service symbol is gone and stays off on the next few starts.
- The service countdown shows the full interval again.
- A re-scan shows no new related fault codes.
Frequently Asked Questions
Can I reset the MG HS Mk2 service light from the dashboard?
No. MG’s handbook says the maintenance display is reset by an Authorised Repairer — there is no owner button or menu sequence on the 2024-onwards HS. It is cleared over the OBD-II port with an MG-capable tool.
Is it the same as the older MG HS (2019–2023)?
The pre-2024 HS actually does let you reset it from the driver’s display; the all-new 2024 HS does not. See our 2019–2023 MG HS service reset guide for that car.
What does a garage charge to reset it?
Usually about a half-hour labour charge on its own, and often nothing extra when reset as part of a full service.
Does the tyre-pressure warning need a tool too?
No — the TPMS relearn is a park-and-drive cycle you can do yourself. Only the service-interval counter needs the diagnostic tool.
If a fault code is stored alongside the service light, look it up on our sister site autodtcs.com.
