2009 MINI Cooper S 2dr Hatchback (1.6L 4cyl Turbo 6M)
I bought my Mini Cooper S 2009 brand new.
It was performing great for the first year but then as it got older although it was under mileage (12,700 miles) in 14 months of ownership, the engine experienced annoying pinging sound specially while on idling. Note* the engine is warm.
I took it to the dealership and was told it's normal.
The pinging sound became louder and it sounded like a diesel engine.
I traded it in for a Mitsubishi Lancer Sportback AWD Turbo Lancer Ralliart.
BMW Mini need to realize that there is a problem with the engine.
Reading the owner forums,
there is definitely an engine concern specially with the S models.
