I bought my '05 used last May and finally got up the nerve to check the oil level (I've been getting a yellow blinking light on the wiper stalk (requesting more windshield fluid). I had a bit of a problem getting the hood (bonnet as you UK people say) open. Finally got the manual out and figured out the hood release by the pax door. Left hand driver over here of course. Then, it took me several minutes to find the little latch that releases the hood up.
Filled the washer tank and then decided to check the oil. I thought the cap was more than a little weird. Got off and found out I was about 1/4 inch below the "add" line. So I topped it off and then screwed the oil cap back on. Perhaps I tighter it TOO much as it "clicked". I stopped right there. Hope the next time I remove the cap it just unscrews normally. If not, I'm not going to mess around with it as I certainly don't want to screw it up. So I'll probably blast down to the local Mini dealer and let them sort it out.
Might even drive a new '13 model while I'm there.
Good excuse to go see them I think.
