Exclamation E93 Problems/Concerns - post them all here!

So I've done alot of searching and have found vague topics on the E93 concerning several issues, and no clear answers...so I've decided to make a thread that will help several people out by isolating problems and concerns with out E93s...and perhaps answer some of my own questions...

1) What is with the fluttering noise in the cabin when the top is up?
ans: it has something to do with the RFTs. There is some sort of a SIB but my dealer said they didn't show any here (Houston)

2) Where is the Vacuum hose in the trunk ?? (for the exhaust mod)

3) when I put my top up, it usually slams down on the roofline and does not lock until I initiate the top-up button upon when I hear it lock down. - what's up with this?

What else....can't think of much right now....ooo: Where is the sunglasses holder?!? LOL - I know there isn't one, I just find it annoying to put it on the side compartment...

if you have anything else to add/answer, feel free. I'm sure it will help alot of E93 owners by keeping it all in one contained thread.

Also, PLEASE STAY ON TOPIC!

Thanks

The fluttering sound is a standing wave resonance that occurs at various combinations of speed and window openings. Mine seems worse at around 32 to 45mph with the drivers side window all the way down and the others closed. You can reduce this by partially closing the window. This should not be confused with the suspension hitting its resonate frequency which occurs here in California at around 65mph due to the spacing of the rain groves on the road surface and the RFT's interacting with each other in the case of my non sport package wheel and tire combo. The best way to avoid this is to drive at some other speed... 75 to 80mph works fine for me.

I'd like to know the answer to #2. I tried finding it several months ago but had zero luck. So, I did the "Golf T" mod by unplugging the hose connecting to the exhaust. Same effect but would've liked doing it through the trunk for less detection.

I haven't experienced the other two issues in my 11k miles thus far. Knock on wood...

Unhappy Security Issue

When you lock the convertible (with the top down or the windows open) doors and storage compartments are locked. If I reach into the car and press the central lock/unlock button, both compartments are unlocked (in fact the center console pops open), but the doors remain locked. So, no one can get into the car, but they can grab your Ipod, registration, etc.

I assumed this was just bad design (or maybe BMW engineers never thought about the possibility). But, I tried the same situation with my 1999 M3. Using the central unlock button, the glove box does NOT unlock. So, I conclude there is a user error – I can’t figure out how to keep things locked – OR there is a glitch in the controlling software. It would seem that when the car is locked from the outside, the central unlock button should take no action – everything should remain locked.

Please confirm your experience. Then tell me how to get something like this fixed.

I have an 08 and no real issues - wouldn't go into sport more on the step from new and they had to replace the microswitch mechanism on it, but that is it. +1 on the smart top - should work that way factory - best E93 mod there is.

SUBJECT
Wind Buffeting/Pressure Noise at Highway Speeds


MODEL
E93 (3 Series Convertible) produced up to 12/2007


SITUATION
When driving at highway speeds, typically between 55-65mph, and the Retractable Hardtop (RHT) fully closed, a pulsating pressure sensation can be felt and heard.

The intensity of the noise increases when driving over coarse surfaces.

Driving outside this speed range will fully eliminate the noise.

This noise is most commonly compared to the noise heard when one of the rear windows is opened slightly on a 4 door vehicle.

CAUSE
A resonant frequency is reached at this speed which causes the convertible top cover (forward of the trunk lid) to vibrate, altering the acoustics inside the vehicle.

CORRECTION
On a customer complaint basis, the following steps should be taken:

Match balance the rear wheel and tire assemblies.

Increase the rigidity of the convertible top cover.

Modify the way in which the rear axle carrier is mounted to the body of the vehicle (does not apply to all models).

PROCEDURE
Balancing Wheels

Match balance the rear wheel and tire assemblies using approved tire balancing equipment.

NOTE: Optimizing the tire-wheel assembly will minimize any vibrations and contribute to the overall effectiveness of the repair.

Convertible Top Cover Rigidity

Park the vehicle in a location where this work can be performed and the vehicle can be parked for at least 24 hours. After the structural foam is applied, the vehicle must not be moved during the 24 hour curing time.

Perform the following procedure for the left side of the storage lid. It will later be performed for the right side.

Follow all applicable safety precautions when performing the following repair.



Use a marker to make a mark on the tube at a distance of approximately A=6cm from the top of the cartridges.



Remove the fastening nut and sealing plug from the cartridge. Next, install the mixing nozzle (1) onto the cartridge and secure it with the fastening nut (2).



Install the included extension tube (1) over the end of the mixing tube (2). Use a permanent marker to mark a line (3) at a distance of B=10cm from the end of the extension tube.


Due to the high viscosity of the 2 part structural foam, it must be warmed in order to flow out of the cartridge properly, and into the void it is intended to fill. Place the cartridge to be used under Hot running water or in a large pail of Hot water to heat the cartridge thoroughly. This should take 15-20 minutes.

Cut a rectangular piece of covering film to 40mm x 60mm.



Open the RHT until the roof panels are in the stacked position and the convertible top cover is fully open. Install the rear module supports (Cartool number 54 0 240) to hold the storage compartment lid in the open position.



Structural foam will be installed in the area (1) shown in the illustration. The left side is shown and is a mirror image of the right side.


Mask off the inside of the luggage compartment as well as the sides of the rear quarter panels to protect them from being damaged during the repair.

Remove the cartridge assembly from the hot water and immediately install it into the applicator.

Connect the recommended pneumatic applicator to a shop air supply. A pneumatic applicator is recommended as a manual applicator can make it difficult to fully fill the necessary cavity.

Pull the trigger and apply a small amount to a piece of scrap material to see the rate at which the foam will come out of the applicator, and then immediately wipe off any excess material on the end of the flexible tube.

If necessary, adjust the regulator on the applicator so that it dispenses at a fairly slow and consistent rate.



Feed the flexible tube into the lower outer-most hole in the cover (1), up to the line drawn previously at 10cm.


Fill the cavity with approximately 60% of the cartridge. When the plungers in the cartridge have reached the line drawn previously on the outside of the cartridge in Step 4, 60% has been applied. The red indicator on the side of the applicator displays the position of the plungers.

Remove the flexible tube from the panel and wipe off any foam that is on the outside of the tube.

NOTE: If any foam spills onto the outside of the cover, clean it off immediately with a clean cloth. Do not use any solvents or cleaning products to remove it.

If the foam was flowing very slowly prior to removing the tube from the panel, it may need to be warmed again before the remainder is applied.



Insert the tube into the larger hole (1) toward the inside of the panel as shown in the illustration. The tube should be inserted until it reaches the outside edge of the hole used previously (2).



Peel the backing from the pre-cut square of covering film and install it over the previously used hole (1). The paper on the front of the film may also be removed..


Pull the trigger until the cartridge is empty.

Remove the tube from the storage compartment cover and wipe away any foam which may have spilled onto the outside of the cover.

Repeat steps 4-22 for the opposite side of the storage lid using the 2nd foam cartridge as well as a new mixing nozzle and extension tube.

Allow the foam to cure for 24 hours.

Rear Axle Carrier Mounting – (Does NOT apply to the 335i equipped with a manual transmission)

Replace the rear 2, rear-axle carrier bushings per repair instruction RA 33 33 101.

While the rear axle carrier is lowered, install a damping disk to the top of each of the 4 sub-frame bushings. Ensure that the damping disk is rotated until it's fully seated on top of the respective bushing.

After raising the rear axle carrier, install the new Stop plates to the bottom of the rear two sub-frame bushings.

SUBJECT
Roof Shell 1 Slams Down on the Cowl when Closing the RHT


MODEL
E93 (3 Series Convertible)


SITUATION
When the retractable hardtop (RHT) is closing from the open position, the front roof shell should slow down as it approaches the cowl. Intermittently, roof shell 1 may not slow down and will slam down on the cowl. When this occurs, the RHT will not latch closed. The convertible top switch must then be released and pressed again in order for roof shell 1 to latch closed.

CAUSE
The contact point for the "cowl panel reached" micro switch, located under the left side cowl plate, is not centered in the centering pin receiver. This causes the contact point to be trapped under the striker when it's pressed down. The micro switch is now stuck in the open position.

CORRECTION
Replace the micro switch with an updated part.

PROCEDURE


Verify that the contact point (1) for the "cowl panel reached" micro switch is not centered in the centering pin receiver.

This contact point (1) is located in the left side cowl plate.


Remove the cowl panel trim cover per Repair Instruction RA 51 44 150.

Remove the micro switch by removing the 2 screws holding it to the striker plate.

NOTE: Lower the micro switch slowly and grasp the stack of spring washers that will come out of the striker plate. These washers must be replaced in the same reciprocal pattern or a rattle will occur.

Place the spring washers back into the base plate and secure the new micro switch.

Reinstall the cowl cover and verify proper operation.

New 2008 335 Convertible and I have the exact same experience.

I can only say WOW ... The number of times I've left valuables in the glove or centerconsole with the top down are too many to count.

I'm contacting the service department at my dealership this week, since this is not acceptable.

One thing I considered though is, could this problem stem from the fact that I don't have the OEM alarm system? Usually you press twice to arm the alarm (at least on other cars) while I only press once to lock it. This could be some kind of weird convenience feature, allowing people still in the car access to the storage compartments.

With the alarm on, is it still possible to open the storage compartments... Anyone willing/able to test?

wait, so if you lock the car, and then open it from the inside, the alarm won't sound?? Also, no sensors in/near the windows?

That's the question... I don't have the OEM alarm so I don't know if the behavior we're seeing differs.

For the most part trouble free....

We have owned our e93 since November and for the most part has been fairly trouble free except for the following:

1) Second day of owner ship, black trunk stoppers went AWOL and fell apart, but was fixed within a week and haven't had a trouble since

2) Clutch spring squeak, WD40 seems to have fixed it

3) Rattle in the top near the rear on the passenger side, this one has been the real nasty one. Been into the dealership twice for the same problem. Both times they have said it is a spring and they have insulated it. Solution works for a couple weeks but eventually returns.

Other than those minor issues, what a great car!

Do you have that fluttering noise in the cabin around 55-65mph when the top is up? I just sent mine to the dealer and they just ordered the special tools for it. Dunno how that's going to work but they said I'm the first one at their dealership to get this performed

The chrome/silver trim around the bottom of the driver's side rear window separates from the body anytime I put the top back up (it slides up about 1/2 an inch when the window goes up). I guess I'll take it to the dealer though my bet is they'll just put some adhesive in there.

I had that problem where when the top is closed you get that open window feeling in your ears.

BMW replaced all 4 tires for me at no cost, pretty good deal. i have the option 19's and they are worth like 650 a tire.

No, luckily I haven't heard that fluttering sound, but perhaps I have been having my radio up too loud!! Also, with the nice weather we have been having I have had it down for about two weeks. But next time I have the top up on the freeway I will make sure I listen for it.
