Hey what up guys!? Names Andrew, and i drive a 09 mini cooper s. Automatic with just and k&n intake. Check the pics!




So for the past 3 years i've been have some problems with my mini, 1st i took it in for a slight stutter while driving, turns out there was a problem with the fuel lines.
next it was overheating, took it in, they said there wasn't a problem.
everything was alright for a while then started making a rattle when it started up on a cold day. Took it in a couple months for a basic maintenance, turns out there was slack in the timing chain and water pump was leaking. Dealer fix the problems then a couple days later the car just starts knocking hard!! I don't know what to do. It seems like there is never ending problems. Has anyone had problems like this?

 

Engine knock like a low oil condition?
Or engine knock like poor / insufficient rated octane fuel?

Yep, those aren't uncommon: the water pump, timing chain tensioner / slack...

The timing chain and tensioner issue are due to owner negligence; sounds like you ran the engine oil crankcase too low.

im sorry, it sounded more like an un-timed engine.
Everything is still under warranty. the car only has around 24,xxx miles. 91 octane was ALWAYS used, since day one. Basic maintenance was always performed on time. I don't know what's going on with this car, i love it but it keeps giving me hell.

 

Then go back and ask for clarification from the dealer.
Since you're under warranty, and the dealer had their hands on it last, have them walk you through.

Do you have a video to post of your running engine?
We could easily tell you if it's normal or not.
