convertible adjustment

#1
My 94 BMW 325ic convertible has trouble getting the top folded down.
I open the latch, push up the front a little, next I press the button, the window folds up, the lid opens, rear window drops down, and then it stops. It won't pull it the rest of the way down. I push up on the front a little again and it starts moving again. Is this a matter of adjusting those tie rod ends that control the lift? If so, do I adjust both and which direction?
Thanks

I can't help you, but would like to know if anyone knows of a manual or documentation on the E36 convertible tops. I have found very little information.

My 94 325iC with a new top (2 years) does the same thing. I can't figure it out. Let me know if ya find out what to do :)

My 95 does the same thing. I didn't know it was a common problem. When I bought the car, the top wouldn't go down at all. Found out someone at the dealership (non BMW) had pulled the emergency disconnect that is under the rear seat. Somehow I managed to get the motors re-engaged apparantly in sync. I thought the fact that I had to help it go down was due to not being precise enough with the timing. Maybe that's not it. And then again, maybe it is.

Not sure if this will work for you but good info to save for a convert. I have a 97 with the full power top. Hope this helps though....

Ressetting the Convertible Top
This is the procedure to reset the E36 convertible top in case you have used the emergency release handle that's located under the rear seat. This works on my '97 328iC, which has the fully-automatic top. It may also work on other E36 models and years (caveat emptor). The owner's manual says to take the car to a dealer for service, but why do that when the procedure is so easy?
The owner's manual describes the method for closing the top manually, presumably in case you have a dead battery with the top down and it starts to rain. The top mechanism is driven by two electric motors that are located in the trunk -- one for the lid of the storage bin and one for the top itself. Closing the top manually requires (1) releasing the two motors from their transmission drives (using the afore-mentioned lever, which through a cable release mechanism causes the motors to pop away from their drives), pulling the top out of its storage bin, and then using an Allen wrench (from the tool kit in the trunk) to fully close and lock the top to the windshield. The allen wrench gets inserted into a socket that's hidden behind a plastic cover at the leading edge of the top, and then you turn it many many times to simulate the action of the electric motor. Note - there are interlocks between the storage bin lid and the trunk that prevent you from opening both at the same time.
Once the two motors have been disengaged, the top can only be operated manually -- the LED in the control switch blinks, and the owners manual says you have to take the car to the dealer to reset the correct operation of the top. The reason is that the two electric motors have to be re-engaged with their drive mechanisms and also re-synchronized with each other (you wouldn't want the top to crash into the lid of the storage bin).
Never fear, there is a fairly easy way to reset all of this yourself. The following is courtesy of Brett Anderson, who came to my rescue on this topic. I was having a new subwoofer and amplifier installed in the car, and the installer had the rear seat out when he decided to pull on the release handle to see what would happen (it has a red tag on it that just seems to scream "pull me" -- who could resist?).
First, manually open the top, placing it back into its storage bin, and then close the lid of the bin as far as it will go. You may need to push down on the lid so that it closes far enough to allow you to open the trunk (there's a safety interlock that prevents the trunk from being opened if the lid is open at the same time). Working inside the trunk, remove the carpet liner from the left side (driver's side) of the trunk. There are two plastic clips that hold the liner in place -- you can pry them out with a screwdriver. Behind the liner are the two motors that work the top mechanism -- one drives the top and the other is for the lid. Each motor is mounted on a spring-loaded pivot mechanism. The gears on the motors normally engage the gears for their respective transmission mechanisms, but when the release lever is pulled the motors pop away and disengage. So you have to push the motors back into their original positions so that the gears re-engage. When you do this the spring-loaded catch mechanism will firmly latch in place. Be sure that the motor is firmly seated into the drive, and not just partially engaged.
Once both motors are re-engaged, get into the car, and with the ignition key in the off position press and hold the top control switch in the up (for closing) position. Continuing to hold this switch, turn the key to the "accessory" position (without starting the car) and hold it there. After about twelve seconds the lid will be sucked down into the locked position, and then after a few more seconds the top will start its normal closing procedure. The motors are now re-synched, and should be all set. Work the system a few times to ensure that both motors are properly engaged and all is well

Thanks

I replaced the left hinge on the hard top and could not reset the motors until I followed the above instructions. It works better than before! The dealer wanted my car for 4-5 hours to take care of the problem thanks again love the web site
