Hello all,

Just a quick one. Ive got 2 knocking noises coming from the rear of my mini cooper when i either go up onto my driveway/curb/any type of gradient etc.... or i can also replicate the noise very well when i do a small slalom. The car is only a month old so im sure its nothing like wheel bearings/cv joints etc....wel, at least i hope its nothing like that anyways. And before anyone says it no its not the seat belts hitting the rear pillars!

Me too. Had my Mini a month now.
I only get one knock (every now and then) and thats when I apply the brakes. It sounds like it is coming from the back. BMW reckon its a loose bit that would hold a spare wheel.
I've also got a noisy clutch. When I take my foot off the clutch pedal, right on biting point, it makes a slight noise. BMW will probably have an excuse for that one as well.

Could be those two rubber balls hanging off the end of the strings that pull the boot cover up when the hatch is open? They just hang down when your hatch is closed so swing freely in an empty boot. They are long enough to hit the sides and the hatch.

the most probably cause is this, or check that the MINI service guy didn't get locked in the boot

Ah i didnt think of those, i will have a fiddle with them tonight to see if they are the problem!

Greenie i have the exact symptoms you have aswell as my 2 knocks from the rear......i also have a slight tempormental knock when i apply the brakes + very noisy transmission and clutch. Im going to take mine inot my local dealership tomorrow just to get it checked over.

[CC07ERS]

is there somebody locked in the boot

[Greenie1]

I've just checked the boot.....
Out popped Lord Lucan, 2 Japanese prisoners of war and Shergar the horse.



A visit to the Dealer, it is then!

i have a knocking from the rear of my mini it seems to be coming from the plastic backing of the boot hatch... i think it jiggles about a bit and is very annoying....

it could another up and coming mini characteristics

[Jonny H]

Right, took my parcel shelf out yesterday and had a little drive. The rattle and 2 knocks werent showing up so the 2 rubber ball thingies were the culprit! Cheers everyone!

May not be the same noise, but the rattling I had in that area turned out to be thr rear hatch ("Boot") lid latch.

I wrapped a bit of Duct Tape around the middle part of the staple-shaped part on the boot lid & the problem has been gone for almost a year now.

It's worth a try - it's cheap & easy!

Can't Hoit!

I have a knocking sound when going over bumps. Its like a load "smack". Im hoping its the little balls on the parcel shelf and not something more sinister.

[Richard Crofts]

Knocking shock?

Balls on string for the boot cover

The rear boot latch itself (mine on both my car knocked and it was fixed by a strip of velvet tape round the latch bar)

Hope it gets sorted

I had the same thing on my 05 cooper and it ended up being the lower control arm on the rear driver side. The bushing was not installed right at the factory and it cracked. The noise I heard and you maybe hearing is metal on metal. The noise will get worse. All covered under warranty, they replace the whole control arm because it's just easier. I recorded the sound let me know if you want me to post it.

Yes please, mine is just about to lose its warranty so I need to act quick.

sorry my cell phone won't let me download it onto my computer. If you open up the hatch and push up and down on the car you will here a cowbell type of noise. That's the noise

Another possibility is the trailing arm bushing. Another thread from 2003 had this occur from backing into a curb and displacing the bushing in its holder (the console in one source). I have the same problem of a displaced bushing but have a question about the replacement procedure. The repair manual calls for removing the trailing arm to get at the bushing. Looking at the bushing mount from under the car, it looks possible to remove just the bushing holder at the top. Several members have replaced the bushing but did not describe the process they used. Can it be done without removing the trailing arm?

[Greenie1]

Car is booked in tomorrow. I will let you know what they say. The Sales guy heard the noise when I took him out.
