Our 2007 MCS is rattling now. Started on cold starts when it started getting below 50 outside. A couple weeks now, and finally getting around to reading up on it. Surprisingly we've been living under a rock the past year, and haven't heard about the issue until now. Yesterday, started the car up from cold, and it was not only making the rattle, but also idling up and down like someone had pulled off a coilpack. It seems that this "tensioner issue" can go into an extreme issue if not taken seriously, and fixed. The car is undrivable, and the idle surging is there to stay. Warming up won't fix this one... Our poor R56 is garage bound until the dealership calls us back with a quote and or solution. It will be towed into the dealership (60 miles away) and out of warranty work will be performed (51000 miles). Might Mini USA give us some good will? We don't know. Hopefully Moritz Mini of Arlington TX will be kind to us. Dallas Mini would be pushing us a new engine purchase quote, so definitely not going there. Dallas Mini is horrible.
Other item of note. Oil was checked and topped-up a week 1/2 ago. Checked oil after the surging started, and it was almost empty! A little over a week drained the engine! Added 3 quarts yesterday. Yes, I have read the "How to check the Mini stick for Dummies" book. This issue is related to loss of oil as some have suggested. Before anyone responds back with oil leaks, so far this R56 has none. Even if it does have a drip under normal engine pressure that happens while driving, it would not eat 3 quart in under two weeks. Right? No smoke out the tailpipe...
Just a hideous little rattle that can lead to big $$$ bucks $$$ down the road. And that distance could be shorter than you think. Be proactive fellow motoring buddies. Before your little Mini mobile croaks.
Timing chain tensioner. Fix it! DON'T let it go to long!
