Mini Roadster check engine light and fuel consumption

My 2012 Mini Roadster throws a check engine light and guzzles fuel like crazy! Suspect inlet VANOS mechanics are faulty. Could be a defective camshaft solenoid valve or power issue. Anyone experienced this?

I had a similar issue with my BMW. Check engine light on, definitely noticed a drop in power, especially at lower RPMs. Fuel consumption was worse too. It could be VANOS failure. Does the engine sound a bit rough at idle? Have you checked the camshaft solenoid valves?

Rough idle sometimes, yes. How did you pinpoint the camshaft solenoid valves? Any specific tests I can do before taking it to a mechanic? Not sure where to start.

Well, honestly, it's tough to be 100% certain without proper diagnostics, but the symptoms sound very familiar. Given the potential defect you mentioned, taking it to a workshop equipped with the right tools to diagnose the VANOS is probably the best bet. A proper BMW VANOS diagnosis isn't always straightforward.

Took my Mini Roadster to the shop. They confirmed it was the inlet camshaft solenoid valve, just like you suspected. Repair cost was around 250€. Runs like new now! Thanks a million for your help!
