Well this is my mini cooper S this morning at 4:30am (yes, some of us have to get up that early for work!), so excuse the darkness, i'm sat in the car holding my camera toward the bonnet, slowly pressing the accelerator to no more than 2k revs. (see movie link) Now, it doesnt do it everyday but i have had my camera in my glove box to try and capture this abnormal noise so i can show my dealer, something clearly is not right! Anyone else have this problem, this is one of MANY that i have and im starting to tire of the ever growing list of problems my new car has. Not happy...off to the dealer
Car has done 2500 miles, ITS NOT A DIESEL!! its a November build 2006 R56 MCS. I have just got back from the dealer, i expressed my concern to there Mini (expert) Technician as to wether i was damaging the engine driving it like this, obviously he could not determine what or why it was making this noise as the engine was now warm. There is a definate rattle from the top of the engine if you hold the revs at 1200 revs just over tickover, when warm, but not like when cold, as in the video. Other problems are as in some other threads on here, when i release the clutch in first- second gear i get that vibrating/rattle noise, like the exhaust is loose or something. It spent 7 days in the workshop last month for dash rattles and a knocking from the drivers side suspension, which they replaced some parts to rectify but its still no different. Also the left windscreen wiper has the most annoying squeek, its not the wiper blades either, if you take the wiper arms off the windscreen and turn the wipers on it still makes the squeeking noise, drives me nuts when its raining! Last week i was driving home on some unlit roads and the Xenons decided to move up and down of there own accord, eventually sticking in the down position pointing about 3 inches up the road, basically it was like driving with my sidelights on, i drove the remainder of the way home with my xenons on full beam and not one car flashed me, thats how low they were pointing! So...its booked in next Wednesday for numerous problems to be looked at, they asked me to take it Tuesday night so they could start the car cold on Wednesday morning to see if it makes this rattle for them.
I love my Mini's and this is my third one, but i am seriously considering selling the car once its fixed. I never thought i would feel this way, but this car has left such a sour taste, im losing faith
That sounds horrific. To my ear, it sounds like big end bearing noise and something within the combustion chambers - even possible that the higher pitched ticking is one of the pistons hitting one of the valves - either that, or there is a broken piston ring flapping around in there.
I would hazard a guess that the clever 'oil pump only runs when it needs to' mechanism isn't working, and your engine isn't getting its oil supply. If this is the case, then running it like this would be destroying the engine. When oil supply comes back, the noises would quieten down, but the bearing surfaces would be badly worn by then .......
Does this noise stop suddenly when it does stop, or does it just fade out gradually?
Take it to your dealership, with this video, and leave it there until they have fixed it or replaced the engine ...........
Well i put the video on a cd and took it to my dealer today, the mechanic watched it and didnt show any alarm at all, just acknowledged that something wasnt right. My drive to work in the morning is not far, only a 5 minute or so journey across town, but the noise remains all the way to work (with me wincing all the way). If i drive it over a longer distance the noise eventually disappears as if oil is finally getting to the parts. I'm no mechanic, but i know that something is seriously wrong with this engine. And thanks for the responses to this guys, i really appreciate the input.
It might be unrelated but my Cooper did something kinda similar once or twice when it was cold,3 degrees temp outside.
Engine was revving up and down and rattlely,switched it off,waited few seconds,then started it and it was perfect???
Then the other day when it was warm,came back to car,started it and it started revving up and down again only this time the yellow 'engine' symbol light came on!
Switched it off,started it again and again it was perfect.
Took it to the dealer who checked the fault memory and told me that 'The exhaust camshaft sensor' (Valvetronic,timing etc)was faulty and my car should be back to me by Thursday.
*****All sorted now,Car perfect.*****
It's a MINI Clubman adventure!

I experienced a noise similar to this from my MCS this morning and once over the weekend. Neither were particularly cold mornings and the noise seemed to disappear after 20 seconds or so on both occasions. The car has only covered 1150 miles so I'll be keeping a listen out for any further tractor-like noises
Good luck CB, hope the dealer gets it sorted for you
Hi.My MCS did the same on Saturday morning when I was setting off to work.So I thought I would call in to my local dealer as it is on my way! As the car got warmer it stopped making the noise! I phoned the dealer up to see if someone could listen to it aswell as the gearbox problem. I took the car last night so they could start it from cold this morning.The gearbox is a fault that bmw are reviewing (for how long who knows!!!) The dealer said they could not hear the noise from the engine! So I went to pick the car up tonight, got In, started it up and guess what? the noise was there!! I immediately went back to the service department and got a technician out. He is going to speak to somebody at bmw tomoz! I think it sounds like the timing chain as it is coming from that side of the engine!!!
Well im sorry to hear your car has the same problem Chip, as i said before mine goes in next week, but if yours gets diagnosed before mine i would really appreciate it if you could post back so i at least have some idea as to what it could be. Thanks again
