Mini Cooper Tyre Pressure

What is the recommended tyre pressure of a Mini Cooper?

To find the correct tyre pressure for your Mini Cooper, then you should consult the owner’s manual and there should be a sticker on the doorjamb of the driver’s door indicating what the correct tyre pressures for your model are. Usually, the front tyres are 2.3 BAR or 34 PSI, with the rear tyres being 2.1 bar or 31 PSI.

What should I do when I see a tyre pressure warning?

Should the tyre pressure warning light become illuminated, it looks like a tyre that running flat, then you'll need to slow down and check what the problem is. It may be a serious puncture in which case you'll need to change the wheel immediately or call for assistance. For slow punctures, then you'll need to have the tyre repaired as soon as possible.

How to check a Mini Cooper tyre pressure?

If you need to check the tyre pressure for a Mini Cooper, then the accurate readings are best taken using a small hand-held gauge that you put on the tyre valve. You could also use the pressure gauge on a foot pump and on a garage forecourt, but these may not be as accurate.

How do I reset a Mini Cooper tyre pressure light?

Once you have inflated all of the Mini Cooper's tyres to the correct pressure, then you can switch off the tyre pressure light. This is easy to do, and you will need to:

  • Start the engine.
  • Use the button on the indicator stalk to scroll through to Set/Info on the display.
  • Press and hold the button until SET appears.
  • Scroll to the ‘Tyre Monitor’ symbol appears, and press reset.
  • Keep pressing the button until resetting appears.

The Mini Cooper tyre pressure warning light should now switch off. If the warning light does not switch off, then you need to have a professional diagnose what the problem might be.

Mini Cooper Warning Lights

Why do warning lights appear when I start the car?

Various lights will illuminate for the Mini Cooper when you start the car and they should go out after a few seconds. If they don't, then there may be an issue with the system being monitored. Try switching the engine off and restarting and should the lights still not go out, then you'll need professional assistance. Be aware that the dashboard warning lights follow a traffic light colour system so they use green to indicate everything is fine, yellow when there might be a problem and read when there is a serious issue.

What do the warning lights on a Mini Cooper mean?

Of the warning lights specific to the Mini Cooper that you'll need to be aware of are:

Brake: The brake system warning light appears to indicate an issue with the brakes.

DPF: The diesel particulate filter (DPF) warning light may also appear to warn that the filter has become blocked.

AdBlue warning light: For diesel Mini Coopers there's a type of exhaust fluid called AdBlue that is needed. When the level is low, the light will flash yellow but when it flashes red, then you cannot start the car until the AdBlue has been topped up.

What does the check engine light mean?

The Mini Cooper has a check engine warning light that will illuminate when there's a problem with the engine. Often, you may find that when you press the accelerator, the engine stutters or there's a sudden lack of power. There's no reason to panic since the light may be a warning of an electrical sensor that no longer works, but it may indicate a serious mechanical problem. You can drive with the engine light on, but you really should have the car inspected as soon as possible to prevent serious damage to the engine.

What does the battery warning light mean?

Should the Mini Cooper’s battery warning light appear on the dashboard while you are driving, then this indicates that the battery is not being charged. This could be down to a faulty alternator or battery, damaged cabling or even a bad electrical connection. You can continue driving but once the battery has been drained, then you will not be able to restart the car. You'll need to take your vehicle to a garage to have the problem diagnosed and rectified before you run out of battery power.

Mini Cooper Common Faults

While the Mini Cooper is a popular car with a good reputation for reliability, there are some common faults including:

The electric power steering pumps: These pumps were the subject of a recall because they are prone to failure.

Oil leaks: The sump gasket and front crankshaft seal are prone to leaking.

High oil consumption: You will need to check oil levels weekly.

Water leaks: Some models are susceptible to a water leak which causes electrical damage.

Gearbox: If the transmission begins to whine, you'll have gearbox problems.

Older mini Cooper models, usually second-generation, also have issues with a loose timing chain, the transmission and water pump. Some models also suffered with clutch failure and variable valve timing. If you own a second-generation Mini Cooper and have timing chain issues, the best place to find a specialist in your area is on our timing chain specialist page.

What are the symptoms of a failing power steering pump?

One of the big problems for older Mini Coopers is the potential failure of the power steering pump, particularly for those models built between 2001 and 2007. Owners will hear a noise coming from the steering pump before it completely fails. You will then lose all power assisted steering and the steering itself becomes heavy. You will need to take your car to a garage to have this fixed.

What are potential problems with an automatic Mini Cooper?

For those Mini Cooper owners that have an automatic first generation CVT model, there could be potential issues. Some owners in America took Mini to court to deal with the CVT and they had theirs under warranty for up to 150,000 miles or eight years, as a result. Another potential problem for an automatic is that the shifting can become harsh and the valve body will need to be replaced. It's important to maintain the automatic models as Mini specifies - for example, changing the fluid regularly will help the transmission lifespan.

How to solve Bluetooth issues on a Mini Cooper?

Among the issues for the Mini Cooper are Bluetooth problems. If this is a paring issue then this is a straightforward connection to resolve:

  • On the dashboard screen, go to the telephone
  • Add new phone
  • Check your phone has Bluetooth enabled
  • Scroll through the screen to find your Mini

The phone will connect and ask for a paring code (which you can create) and you then input this code. Once connected, the Mini will ask what features you would like to enjoy.

However, some Mini Cooper owners may find that the car may disconnect and will struggle to connect once more. Simply go into the telephone menu, scroll down to Bluetooth and disable it and then re-enable it to connect the phone to the car once more. You may need to check whether your phone is compatible for connecting.

What kind of potential clutch problems may arise on a Mini Cooper?

One of the issues for the clutch in a Mini Cooper is that you may find it starts juddering quite strongly. This indicates that the gearbox control is not properly controlling the gears, leading to the car to stutter. You may also find:

  • Issues with the clutch hydraulics
  • Engine revs faster 
  • Grinding noise when clutch pedal depressed
  • Vibration felt when changing gear.

In these instances, you will need a professional to inspect and fix your Mini Cooper.

If your Mini Cooper suffers any of these problems, find a clutch specialist in your area to conduct a safety check and potential repair.


Other Common Mini Cooper Questions

What Type Of Oil Does A Mini Cooper Take?

The recommended engine oil for a Mini Cooper is a synthetic 5W-30 oil - this is what Mini use, but they also approve 0W-30 and 0W-40. The oil will need changing every year or 12,000 miles along with the oil filter.

How Do I Find A Mini Cooper’s Engine Code?

If you need to know the engine code for your Mini Cooper, then the information is in the owner’s manual. First and second-generation Minis have ‘R’ series model numbers, while third-generation models have ‘F’ series. This means the Mini starts with R50 and the engine code will be W10 for the Cooper. Most early versions have the W10 engine code and W11 or N18 or N47 for the diesel versions. Later versions are B37, B38, B47 and B48.
