What these short clips cannot convey is how loud the knocking/tapping is, its really alarming!

Listening to those two clips several times back to back (with headphones on this time) I can definately hear the difference in the volume, for sure.

Based on the timing of the noise (consistancy - increasing with RPM), and the volume (increasing when cold) I still can't help but think it's a relationship between the DFI and the "on demand" design of the engine cooling system.

Whether or not it's detrimental or not is to be deturmined. I'm VERY interested in hearing how this all plays out as I have some vested interest in this myself (I pick up my car next week! So...).

I wonder if it is something to do with starting and stopping the engine without letting it warm up. I know that this can be bad for the catalytic converter and maybe the management system gets confused.

Has anyone any evidence that this diesel noise is something to worry about?

My MCS sounds pretty awful when cold or at low speeds in a high gear but I tested a MCS demonstrator at the dealers and it did the same. I think the sound is the"Peugeot" contribution to the engine and the performance comes from BMW!! LOL.

I videoed my Cooper S today and sounded awful just like the other videos and just wondered what you all thought

Mine has also made this diesel noise 3 times now. Luckily the mechanic at my dealer heard it too when I took it in to complain about the strange noise on pulling away at between 1000 and 1500 rpm and at low rev gear changes. They have asked me to take it in on the 2nd of April with the intention of changing the timing belt tensioner. Maybe this will cure both problems. Thankfully though they have heard this noise and know that it is not right!

DaveyC · Mar 25th, 2007, 11:32 PM

Dealer says new Timing Chain Tensioner has resolved my diesel sound. Will let you all know when I pick it up when they solve the gearbox noise.

GarryThomas · Mar 25th, 2007, 11:36 PM

I've just heard some of the clips some sound awful, others not so bad.
I'm supprised that BMW haven't mentioned that a performance engine
is supposed to run loose when cold, and when it's at normal temperature should run a lot more smoothly.
Are the exhaust manifolds the same temperature at each pipe? as the engine warms up if one is colder than the other it just may have a Intermittent faulty plug, and cuts in a few hundred yards up the road.
But to many people seam to have the same problem.

if the gearbox noise is a grinding/grating noise on changing down to 2nd from 3rd or 4th, it is a new dual-mass flywheel and clutch that is required as that is what has fixed mine (for the moment..

) Just for your info.

Thanks for the info CraigD but the problem seems to be on starting from cold for the 1st minute or 2 and then settles down to 'normal' engine running noise.

m1m0 · Mar 27th, 2007, 08:44 AM

So what is the deal with this noise then? Are we all just supposed to put up with it? I don't care what anyone says... no brand new car should make noises like this!

It seems that the only person who might have had it diagnosed and fixed is DaveyC, but perhaps that was a different problem producing similar symptoms?

My car is going in on thursday - with 9 other issues - and it'd be good to get this one sorted and give the service dept as much info as possible. Throughout this thread I've seen mention to the following items being replaced:

Timing Chain Tensioner
Cam Chain Tensioner
Timing Belt Tensioner
Chain Tensioner Piston

- presumably these are all referring to the same thing?

Thanks!

DaveyC · Mar 27th, 2007, 08:57 AM

Been to the dealers today to listen to the engine after the replacement of the timing chain tensioner - sound has gone.

What is left is the tapping noise that is part of the direct injection system used, and a slight rumble on the cam gear that goes if you remove the brake serer vacuum pipe.

They are checking the gearbox noise in 1st/2nd - they have been told to check the exhaust front pipe heat shields

I emailed this video of my car to Bmw mini customer services over 3 days ago now and havent bothered replying

any one got any other address i can send the link to???

SIMIN · Mar 29th, 2007, 01:14 PM

Got exactly the same noise, it a late dec build, done 2.5k miles and makes the same noise. Been to my dealer and i am now waiting for a new ALTERNATOR and drive belt!!!! they told me it would be ok to drive, but am not so sure........ Does the noise also occur when slowing to almost stop in 2nd, then putting your foot down as if pulling away, always at around 1200rpm ...it's very odd..... and everyone thinks is drive a diesel too!!!

kinchjet · Mar 29th, 2007, 08:50 PM

We collected our MCS yesterday and all seemed Ok at the dealer, but when we arrived home(30 miles) I heard a noisy tapping sound from engine.sounded like a diesel!
Called out Mini Care and was advised that this is due to the injector solenoids actuating (some can be worse than others)

He said as the noise goes on overrun ( injectors shut down) this was definatley the fault, I,m not so sure and will go back to dealer on saturday to listen to other engines.

Has anyone else been old this is cause of noisy engines?

Wipeout · Apr 3rd, 2007, 07:19 PM

My car now has 2500 miles and with every mile then engine gets worse. It sounds awful.

I wish I had never bought this car.

CC07ERS · Apr 3rd, 2007, 07:26 PM

Iam leaving mine with them as the noise is now bothering me big time !!!!!!!!!!!!!!!!!!!!!!!!!!! 2000 post

my car made the diesel noise this morning, will monitor it then it'll be off to the dealers, maybe we should all get together and do a group complaint to MINI and get some sort of recall going.....just a thought

My MCS is 2 weeks old (450 miles)... at weekend on Saturday, cold started car to briefly move into garage as was going away in our other car for overnight stay. Then, on Sunday took car out garage for a spin... experienced the "diesel" noise on startup/low revs/first few miles. That's the only time I've experienced this, so yes there is maybe something in the "start/stop without letting warm"?

m1m0 · Apr 10th, 2007, 09:03 AM

Hmm.. I thought that too until we left the car out of the garage one night after a long-ish drive. Next morning we had the dreaded noise, just as bad as ever... so unfortunately it doesn't seem to be to do with starting/stopping without letting the engine warm (in our case at least).

m1m0 · Apr 10th, 2007, 09:05 AM

Oh and forgot to mention, the technicians at the dealership were apparently able to reproduce the noise last time the car went in for some work to be done. They agreed that it's loud and nasty, but are convinced its normal... make of that what you will.
