MG 3

The supermini, and the longest-running modern MG — the first generation ran essentially unchanged for over a decade on a naturally aspirated engine and a manual gearbox, which makes it one of the simplest cars in this catalogue to diagnose. The 2024 car shares only the name: it is a full hybrid on a new platform, so nothing learned about the old one transfers.

Information, not instruction

CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.

Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:

  • The car — make, model, year and engine. The same fault behaves differently on each.
  • What you measured, not only what you replaced.
  • What actually fixed it — or that nothing did, which is worth knowing too.
