Typical Issues and What to Watch For
Lower Control Arm Bushings
Their lifespan depends on driving style and where the car is stored. The S models are harder on bushings and usually need replacement between 50K and 100K miles.
- Non-S models get up to 100K miles on the original bushings.
- We suggest inspecting all suspension bushings at every opportunity.
- Clunking under low-speed braking and leaking fluid from the bushings are typical signs of failure.
Oil Leaks
- Most MINIs develop oil leaks at the valve cover and the crankshaft position sensor.
- Leaks at the oil pan gasket are not uncommon.
- The crankshaft position sensor O-rings tend to deteriorate and leak at about 75k miles.
Engine Mounts
Excessive or newly developed engine vibration is a good sign that one or both mounts are failing or have failed.
The engine mounts should be inspected between 60K and 70K mile mark. We typically experience failure at about 75K miles.
Power Steering Cooling Fan
MINI Coopers have a small fan mounted under the car that cools the electric power steering pump. Unfortunately, this is prone to failure and, because of placement, sometimes road damage.
When this fan isn’t working, the power steering pump will overheat and intermittently stop working. After a short time without cooling from the fan, the power steering pump will fail.
The cost of this repair can be avoided with consistent inspections.
Radiators
Small radiator leaks in MINI Coopers can occur as they age. The most common symptom that the driver notices is the radiator fan remaining on for an extended period after shutting off the car.
Keep an eye on your coolant level. If it starts dropping, get your car to a qualified MINI service center.
CVT Transmissions
Automatic transmissions in 2001-2004 non-S MINI Coopers are a source of confusion and problems. They have a ZF CVT (continuously variable transmission) that has a relatively short lifespan.
Over the years, we have found that these transmissions are often misdiagnosed as needing replacement. On lower mileage R50s, resetting the software and changing the fluid can bring them back to life.
