Why your MINI engine light is on or flashing

Which MINIs does this page cover?

This page covers the engine management light on R56-generation MINIs and later, petrol and diesel. For other BMW and MINI work, see our BMW and MINI specialist page.

If you are not sure which engine your MINI has, put the registration in the enquiry form and we will check.

What are the symptoms?

Owners usually describe one of these:

• the engine light stays on
• the light keeps coming back on
• the light is flashing
• the light comes on with juddering or shaking

When you book, tell us when the light first came on, whether it is steady or flashing, and what the car was doing at the time. If the light is flashing, or the car is juddering, have it checked as soon as you can.

What causes it?

The light means the engine’s control unit has stored a fault. Many different faults in the engine, its sensors and its emission control systems can do this, so the symptom alone does not tell you which part has failed.

Two points are worth knowing before you book:

• High-pressure fuel pump failures have been recorded on the petrol engines used in R56-generation MINIs.
• MINI diesels built from 2013 to 2017 have been recalled over the EGR cooler, so check your recall status first (see below).

Beyond that, we do not guess from the symptom. The fault memory has to be read and the cause proven by testing.

How do you confirm the fault before fitting parts?

A fault code is not a repair. A code tells us which system has seen a problem, not which part to replace. Before we quote for any parts, we:

• read the fault codes stored in the engine’s control unit, using our diagnostic equipment
• read the freeze-frame data, which records the conditions at the moment each fault was stored
• record the faults before anything is cleared
• test the part or circuit the data points to, and watch live data on a road test where needed
• check whether a recall applies to your car

We then show you what we found and send a written price. No part is fitted until you give your written approval.

What does the repair involve?

It depends on what the tests prove. We repair or replace only the part that is proven faulty. If we find more than one fault, we price each one separately and you decide what goes ahead.

Once the work is done, we clear the stored faults, road test the car where appropriate and read the fault memory again to verify that the fault has not returned.

How long does it take?

It depends on what the tests find. A fault that comes and goes can take longer to reproduce than one that is present all the time.

Before any repair starts, you get a written price and a promised time for your next update. If the car needs to stay with us, ask about a courtesy car when you book.

Is there a recall for the MINI engine light?

MINI diesels built from 2013 to 2017 have been recalled because coolant leaking from the EGR cooler can form deposits that, in rare cases, can catch fire. The remedy is a revised cooler and an engine software update, free through the manufacturer’s network.

An engine warning lamp that shows a fault can also be a Major defect at the MOT, so it is worth finding the cause before your test is due.

Whether a recall applies depends on the individual car, so check your registration on gov.uk. Recall work is done by MINI’s network, not by us.
