Mine car has the dreaded "Convertible Top not Locked" warning going on every time I go above/below 5mph again. Anyway to stop it? Also, with the top closed/locked, how do you get to your sensors to check them. My non-BMW mechanic shop replaced a sensor and it worked for 6 months. Now it's back again.

You can try "resetting" the car (so to speak) by manually putting the top down and back up to get the sensor thinking the top is actually up.

^ Many of us that had the issue were able to get the top to go back up (or down as applicable) after manually doing the task. Try putting it up manually and then see if it will allow you to do it automatically.

Mein Auto: 650i
Add me to the list! I purchased an 07 650i last week and it started the "convertable top not locked" and locked out my windows on the way home from the dealership. I had to make a trip the next morning, so just said I would take it home and try to figure it out. As I was driving down the road later that night the flashing red light mysteriously stopped and I was able to get my windows up. I figured out to use the hand crank and by locking it with that sometimes makes the light quit flashing....then I put the windows down, and then the top will operate. This evening.......did it again but no dice on my fix! So aggrevating. My first BMW......prob my last.

Looking to buy a 6er vert here in Phoenix. Does the error that you guys get only happen when it's hot, or does it happen when the temp changes?

I think it happens all over. No real way to say for sure if it's actually the heat. I have the problem and I'm in NY and it just started to happen recently when the weather has been perfect, 70's.

I guess the question I should be asking, based on all the research I've done here
on bf is: should I even take the risk of buying a vert? I notice more complaints with the vert than praise, so this is a very hot issue at my point. Wifey wants a vert, I want wifey to be happy. Vert wants to act funny.

Bonus question to the vert owners with the problem: if given the
choice, would you go with the coupe instead?

^ Let me put it to you this way...I am the king of the Convertible Top Not Locked error - 10 visits to the dealership over 1.25 years and got the roof replaced in my 645Ci. I just traded that car in for another 6er convertible.

I admire your enthusiasm for the 6. I want it pretty bad myself. It appears to me the 04 to 06 6er verts are the main culprits. Anyone with the same problem on 07s and up?

More questions on 2005 645Ci Convertible "Convertible Top Not Locked" errors. I performed the mod that makes slots to rotate slightly the sensor in the top that creates this error per a BMW service bulletin. The error message did not go away plus I have one more issue. I manually rolled the rear window down, It will not go back up. I'm not sure if this is because the "Top not Locked" message/software preventing the Elect switch from work? or some other reason.

Question 1: So any tricks to get the window to roll up manually or with powered switch?

Question 2: Any way to reset the error message so I can see if the mod to the sensor mount worked?

I guess I could pull it back off and widen the slots a bit more.

In hind sight, this is such a fantastic car, except for my convertible top problems so I'd definite blow off this LEMON top on the 2004 to 2007 versions.
It seems to happen less on the new ones but that might be just cuz they are still under warranty and owners aren't gripping on this website yet???

Just in case someone wants to try to manually check your sensor(s). Here what I did on my 2005 645Ci:

Pull screwdriver and manual crank allen wrench from Tool kit in the trunk above the battery.
Use screwdrive to pop small top panel between rear head rests.
Insert Allen crank tool, rotate clockwise to bring the rear window down (this was pretty hard to turn).
Put down remaining windows.
Insert Allen crank tool in convertible top small hole above the rear view mirror. Crank as shown in icon near this slot to release the front window locks.
Be sure to completely release/turn the crank until it becomes hard/stops (As after the top is released, there are still mechanisms that are in the side supports that need to be fully retracted.
All this is in your owner's manual so refer to it. This is just to help out as I ran into a couple of issues.
Get help to lift rear top up 90 degrees. (You do not have to pop the trunk latches/release for the boot cover if you are just working on the one sensor shown in this link).
http://www.m5board.com/vbulletin/e63...ml#post1891632
You do have to pull the 2 trunk releases/latches if you want to completely put/stow the top down for driving.
See picture in the above service bulletin for what the sensor/mount looks like.
Use torX screwdriver to remove the 3 bolts that secure the mount to the mechanism.
Be careful to remove the sensor connectors.
Once removed, unscrew the 2 bolts that hold the sensor to the mount.
Use a file or drill to elongate the 2 slots as shown on the above link service bulletin.
Replace mount/sensor and mate connector..
Then manually close the top per same process in reverse as shown in owners manual.
If you have problems closing the top to windshield, be sure you have fully operated the crank in the open direction before closing.
It helps to have 2 people so 1 can hold the top closed while the other cranks the latchs closed.

Good luck if anyone tries this. Let me know if your sensor mount mod works for you.

Spot - you can manually crank that window up (it's an absolute pain, but you can). Page 43 in the manual.

Well, just got mine back and they performed the the realignment of the "Rotational Hall Sensor" so we will see if this hold up. Plan to use the heck out of it this weekend to see what happens.

My top is now working. I had did the rotational sensor mount mod to elongate 2 of the 3 mounting holes but my "conv top not locked" message was still there. I read on this or another 645Ci convertible forum topic that you could use your key from outside your car to open close the top. This worked, I used the allen crank to slightly open the top and then used the key to complete the operation and my top went down and the "Convertible Top Not Locked" message and dreaded 5mph chime are all gone.

Now since I am not under warranty. Do I leave me car in the garage with the top open and only bring it out on nice cloudless days or do I use it and see how long this fix lasts. What a piece of crappola this top is for such a nice car.

Again, I recommend to all person considering the 2004 to 2007 (at Least) BMW 645 TO BUY the coupe. Stay away from this LEMON top.

Thanks for everyones help getting my car fixed (at least temporarily).

Use it the way it should be used. Top up or top down as you see fit. Now that you know what the issues are and at least seems to fix the problem, use the heck out of it and see if it works all the time. If it gets stuck again, at least you know the steps to rectify the problem. I have to agree, BMW could have done a much better job on the convertible mechanism.

The mechanism seems to be fine. The sensors and sensor alignment are a piece of junk that making millions for BMW. I'd like to see a rack up of how many replacement sensor parts they have sold and what the total labor charges are to remove and replace them. Any lawyers out there that can research this? If we had these numbers this would probably lead to a Class Action Suit.

But you are right, I should try to use it some now after I've gotten thru the tough part of learning how to troubleshoot and fix it myself.

This is my 3rd BMW and 2nd BMW convertible. 86' 325e coupe and a 96 325ci conv and it had a manual close that sucked and they changed it to auto the next year. (think it was a 96).

Second trip to dealer for the problem appears to have fixed the problems.
Some notes from that second visit that might help others:
1) It matters which sensor they replace with, guessing some older parts just continue the problem.
2) The shop supervisor had to be involved and talk to BMW tech line and fiddle the adjustments to get it all just so.
3) Perhaps most important the motor that actually closes/locks the top at the windshield fried while they were doing the adjustments and had to be replaced. My gut tells me this might be part of the problem
Everything has worked just fine since then (fingers crossed) and dealer was very generous in charging me really just for parts on this second round, I'd guess they picked up 4-8 hours of tech labor.

Damn, today the top not locked error popped up a couple of times. Once on my wife and once on me. I would think that this will increase in frequency now.

I wish it would give me the full error with the red warning over the 20 mph. That way I could take it in and they would have something. I have 2 weeks left on my full warranty and then it is CPO. I would rather get this done now!

Mein Auto: C5, 740, 525, E36M3-gone
Hello all.

A couple of weeks ago I asked whether or not the 6'er scratched your power itch. After numerous, borderline rabid AFFIRMATIVE responses I started to nose around a little. Drove a couple of cars, got the bug, started scheming a very premature move out of C5 vert into a 6 series vert. Then, my wife got back home from a trip to Africa and I returned the 740 to her and started driving the C5 again and realized that "this doesn't suck" so I relaxed. Then wife and I spent a 3 day in La Jolla in the Vette, during which I put top up and down manually numerous times at about 12.758 seconds per event (yes there actually is a tie in to this thread) and I really fell in love with Vette again. Then I saw a white 650 vert with black top and saddle interior and almost hit the ground when the blood rushed out of my head...
As far as my wife is concerned, she came to the realization long ago that I am a lost cause, so her comment was "The 6 is not any less conspicuous or flashy than the Vette, but at least it is a BMW so you can finally get that mullet cut off"

So I revisted forum today to feed the re-developing habit, came across this thread and my sphincter started tightening just thinking about dealing with this issue. It seems that the consensus is that post 2007 the problem occurs less, but I am not currently in a time of life where I want to spend that kind of money.

So for the Big Reveal and wrap up... It seems I have counted about 10 - 12 active sufferers of the Top Unlocked Alarm problem, how many early year vert owners have not had the problem?

I've owned my 05 for about 15 months and have not had any issues with the top. Currently have 63K miles on it and it is under CPO warranty until August 2011. My only complaint is the darn front break squeal. I-drive says pads aren't due to be changed but can't stand the noise so break change is coming.

I am happy to hear that you have been "convertible top malady free."

Your best course with brakes is to replace with OEM parts. I-drive is accurate regarding pad wear and replacement. There is a "closed" electrical circuit on the wear sensors. When pads wear down the plastic end of the wiring also begins to wear. When the bulb wears through and the wiring is also worn through, the circuit is opened and you get the service brakes message.

Brake squeeking is typically due to something happening on the back of the pad. OEM pads have a nice rubber backing that that eliminates the metal to metal squeeking that can occur from aftermarket pads that do not have the rubber backing. If your brake noise is not squeeking but grinding, it may be due to the PO replacing pads with aftermarket metallic pads and the noise would be coming from the pad itself.

Several BMW's ago, I had a 735iL and the first time I changed brakes I went aftermarket. I took the pads off within a month and installed OEM. After 15 years of always having at least one BMW in the family I have never used anything except OEM and I have never had any problems with brake operation or noise. I have found that I typically need to replace the rotor on the second pad change.

Thanks for your response and I hope you get your brake noise resolved. Those types of noises are very annoying.

jazzcat, thanks for the input. My independent shop said the brakes had been changed previously and they used BMW pads. I suspect the noise is coming from the wear sensor rubbing on the disk. I will definately use BMW parts; from reading other posts your description of using after market pads seems to be correct.
