Supercharger Belt Squeel on new MCS?
#101
Hello all,
Add me to the list of people who had this problem. It started at about 3000 miles and continued all of the way to 12,500 and my first service (it was on and off, mostly on). Luckily they were able to replicate the sound and changed my fan belt. No noise since (about 50 miles on a very hot day).
Fingers crossed.

I can't believe they told you it was normal.
Good luck - Bodinski

o i totally agree with u ......trust me.....after workin for bmw/mini for the ast 5 yrs ive seen alot of things that are dumb designs and still are to this day. In all honesty.....i think thats the worst excuse id have to tell my cust with this type of problem on a brand new car....." Well sorry sir....after buying your 25k car the belt noise is normal and you have to deal with it "

If the noise my car was making is normal, I don't want a normal car. Instead of normal I described the noise as as annoying, irritating, obnoxious, and most of all embarrassing.
I can't believe that someone could look at someone else and tell them that it is normal and still have a straight face.

You n me both......i cant tell my cust that with a straight face myself. They have changed the belt and tensioner and the problem is still there. I can only think ita a bad pulley maybe and it hasnt been found yet or something stupid.....You never know..... A bad batch of belts will do this.

On my Mini, they changed the tensioner, vibratio dampener, the belt,and a crankshaft pulley with chipping paint. I understand that the crankshaft pulley problem happened on the early models approx. 2 years ago. Don't know if it is related to the problem. Mine has been squeel free for 4 days. Not many miles though. Lets cross our fingers.

Tomorrow I am dropping off my MINI at the dealer to get a new supercharger after a 4 weeks wait. It is going to take at least 2 days at the shop but they tell me that is going to cure the squeeling for good. I am at 800+ miles and the sound still the same, no signs of leveling down like in some earlier posts. I will let you know how it turns out and what other info I can get from my dealer. What intrigues me is that everyone here has the same problem and a lot of possible (no) solutions.

Here is Mini's bulletin on this matter.
SUBJECT: DRIVE BELT NOISE
MODEL: All R50,R52,R53 built from April 2005 to present with W10-W11 engine.
SITUATION: Customer complains the engine exhibits a hig-pitched squeal from the engine accessory drive belt. The noise can occur at all engine speeds,mostly accurring in the 2500-RPM range.
CAUSE: Root cause is under investigation
PROCEDURE: One of the following could be the cause of the complaint. Please follow the procedures outlined below in order.
1. Alternator Alignment
a. Loosen the 3 moutning bolts that attach the alternator to the mount two revolutions, do not remove the drive belt during this process. Leaving the drive belt in place causes a natural alignment of the alternator.
b. Retighten the bolts and torque to spec.
Drive belt removal MINI Cooper S vehicles equipped with W11 engine and F21 6speed automoatic trans ONLY
2. RUST OF FLAKING PAINT ON THE PULLEY
a. Inspect all pulleys for rust or flaking paint in the belt contact surface. Removal of the drive belt will be necessary.
b. Using a 3M Scotch Bright pad or similar pad, clean the pulley until the rust or flaking paint is removed.
c. Before reintalling the drive belt, inspect the belt for damage, foreign material in contact surface and length of the belt. Compare the belt length to a new belt from parts dept., replace as nececassry or reinstall old belt.
3. DRIVE BELT IS HOPPING OR THE BELT TENSIONER IS BINDING
a. Inspect belt tensioner using a special tool to release tension. Remocal of the drive belt may be neceassry.
b. If the tensioner feels soft or appears to be binding and will not re-apply proper tension to the drive belt, replace as necessary.
c. Before reinstalling drive belt, inspect the belt for damage` as stated above.
4. SUPERCHARGER DIFFICULT TO TURN (W11 ENGINE ONLY)
a. In some circumstances this could be caused by a difficult turn or binding Supercharger....DO NOT REPLACE THE SUPERCHARGER. Submit a PUMA case to the Help desk.

It's at the dealer, left it last night and got a loaner on the mean time, they told me it would take 2 days so I guess tomorrow is D day. I'll sure let you know what happens as it is really strange that a car that has been so long in production comes up with this problem. BTW where is the beer icon? Ooops wrong site.

I believe that the Mini Service Bulletin that 1FSTMINI provided is missing a couple of steps...
1) When customer brings car in complaining of squealing noise, look at said customer and say that it is a normal noise that will eventually go away. Make certain to keep a straight face through this discussion.
2) Get in car and drive around. Make certain that customer is in passenger seat. Turn radio volume up until noise is no longer noticable above the noise of the radio. Look over at customer, nod, and state, "I do not hear the noise you are describing!". Please keep a straight face during this conversation.
3)Inform customer that this is a way to bring more people's attention to the Mini that you are driving. Please keep a straight face when conveying this information.
4) if none of the above work, go to the alternatives noted below...

Well, I have to be thankful that I did not experienced that, my dealer from the offset on the first visit adjusted and lubed the belt, on second visit they told me about the superchager but that I had to wait for around 3-4 weeks. That I did, and now the car is in the shop, no news yet.
Shame that some dealers treat people poorly and I do not understand but at the end is a profit for the dealer, they charge the work to MINI so in most cases they are more than willing to repair "anything" under warranty.
About the PUMA, I tought I would get a nice pair of sneakers for my trouble, hehehe, not

1FSTMINI, you were right, I got back my car today, so far no squeeling or something, what the service order described is:
Replaced Alternator Belt
and
Retorque Alternator Bolt
So I hope that's that, but still think it took to long for my dealer to order an alternator belt (4 weeks!!). Well, I guess they were hoping it was going to cure by itself or something.

3,000 on mine since they applied the JCW belt and still squeal free. I talked to my dealership the other day for an update. My dealership had three cars at the same time with the same issue that were all fixed by applying the JCW belt. He wasn't sure but he thinks that MINI changed their parts supplier for the belt tensioner and that this *may* be some of the issue.
