My countryman S All 4 has around 10000kms mileage. it is still new car.
But there is annoying rattle sound from engine area, I suspect it is coming from passager side.

At around 2-4 gears, if I push the gas pedal slowly (to reduce the sound from engine), I can hear the ticking/rattle sound. If I release the gas pedal, the sound will go away. Sometimes it will still ticking from around 1-2 seconds.

I took the car to dealer first time. The person test drive it in highway, hardly notice the ticking. He think the car isn't warm up and maybe sound from water pump and injector. (But I have drive more than 10 mins to dealer shop).

Second time, I still complaint about this to dealer. they test the car by themselves. At the afternoon, they said they compared the same model, it is normal for MINI or BMW. The sound is from injector.

Finally, I got paper report from them. It is written as "Suspect injector"......
So they are not 100% sure where does the sound come from in my opinion....

Did anyone has the same issue?
I google the problem, hardly to find some results. There is a old thread (year 2005) from min2.com shows they fix the ticking sound when replacing the "harmonic damper". I mentioned to service advisor, he thought the thread is too old and MINI should have fixed this.
I also heard someone changed the tension or supercharge belt. But my car is new, shouldn't have such issue??

 

My Countryman has 5000 miles...ticks and clatters like crazy until it warms up. Its normal.

The 2005 MINI engine you read about online is a completely different engine than in your car.

 

Thanks Flav.
Yes, I lived in Canada and it is very cold in winter. It ticks like crazy at beginning. But I don't see it goes away after 20 mins. I drive local+highway for about 20 minutes. The ticking sound still there when drive at low speed.

The ticking is not always there. It shows up when I push the gas pedal. It goes away when I release the gas pedal... Is that still normal?
That's why I notice there is ticking. It keeps silent when release the gas pedal, and ticking noise when push the pedal. It is obvious difference.

It hard to hear the sound when drive in highway, because some outside noise and engine maybe more louder.
