Re: Need to adjust the timing for convertible top 1999...
It is (normally) not adjustable. If a mechanic told you the car is out of time, check with another mechanic.
If you have a damaged reluctor wheel, the crank position sensor can get mis-readings and cause the car to fire out of time. I recently saw a Lexus that had its reluctor wheel damaged during a timing belt replacement. I have heard of similar mis-haps on BMWs. A related problem is damaged shielding on the crank position sensor lead. Such damage alows electrical interference to get in to the ignition trigger signal from the sensor, and can cause mis-fires.
If you put in an aftermarket performance "Chip" in your ignition computer, it will change the timing program. Such chips are illegal in most states and may be detected in an emissions inspection. Is that what happened to you?

i had the same problem with my 1998 bmw 323i and right under the back drivers seat there is an emergency convertible top lever with a orange tip on it. i removed my back seat to make it easier. when you pull that lever, you will hear a bang sound. that is the sound of the motors disengaging.(there are 3 top motors in the trunk by the left side panel when you remove it) you will then have full access of movement to either put the top up or down. But before you do any of this, i Really suggest you watch this youtube video. if this link doesnt work, you can go to youtube.com and type in bmw convertible top motor stuck and click on the first link BMW DIY #3 E36 Top Repair. I suggest watching the whole video first before attempting or if you want, you can have a mechanic do it! hope this helps
Check fuses first.
Assuming that the fuses are good, use a test light to determine if there is power at the motor.
If there is, repair/replace to motor. If there is not, check for power before and after the switch. If there is power before the switch, but not after, replace the switch. If there is power after the switch, check the wires and connections between the switch and motor.
If there is no power before the switch, check supply wires.
You have to put hydraulic fluid (power steering fluid will work too) in the convertible top motor. The motor is in the trunk, on the left hand side, under a panel. Pull the panel off and that is the electric motor for the top. You'll see a reservoir where you put in the fluid. Put in the fluid and you'll be good to go.
You are probably low on fluid.
Behind the rear seat is the motor/pump/reservoir.
With the top down, fill the reservoir with ATF.
Cycle the system a few times.
Repeat till the reservoir will accept no mor fluid.
Chedk the lines and cylinders for leaks. The fluid must be going someplace.
You can change it to a manual top by removing the bolt at the top of the cylinders and lowering the both shafts down into the cylinders.
The convertible top motor and release lever are in the luggage compartment. From the Bentley manual, the following general procedure is suggested in order to close the top in an emergency situation. Main motor. To release the top linkage from the motor, lift the left corner of the rear seat to access emergency release handle. It is then possible to push the top manually to a near closed position. In case of the semi-automatic top, simply attach and lock the front latches. Front latches. Once the fully automatic convertible top has been released from the motor and manually pushed to near-closure, emergency latching of the top is possible by using the S-shaped hex key provided in the emergency tool kit(attached to the trunk lid underside). First, remove the the plastic cover over the latch motor in the front bow of the convertible top. Next, use the hex key from the tool box to crank the front latches shut.
