What goes wrong
The CVT automatic in R50 Mini One/Cooper models is one of the most notorious gearbox failures of the 2000s. It slips, whines, judders and then fails completely, typically between 80,000-150,000 km, and a rebuild or replacement usually exceeds the value of the car. BMW faced class actions over it in the US. On a NZ budget buy, treat any CVT R50 as having a gearbox with a use-by date — manual cars are vastly safer.
What you would notice
- Whining that rises with speed
- Judder or slip pulling away
- Flaring revs
- Gearbox warning light
- Clunk into Drive
How to check it
Where to look. Transaxle gearbox, left of engine
Test drive from cold: listen for whine, feel for slip on take-off and check kickdown response.
Any hesitation, judder or warning light means walk away.
Ask for CVT fluid change records — almost none exist, which tells you the risk.
What it costs to put right
$4,000 to $8,000 at New Zealand independent workshop rates. That is for this job on its own, not for the car.
Ask the seller
- “Has the CVT ever been rebuilt or replaced?”
- “Has the fluid ever been changed?”
