Power Folding Top System Components
The power folding top system consists of the following components:
• Folding top control (FTC) module
• Body control module (BCM)
• Folding top control switch
• Serial data communication
• Folding top cover latch actuator
• Folding top cover pull down actuator
• Folding top pump motor with valve manifold
• Position switches and limit switches:
- Pin receiver switch
- Luggage barrier switch
- Folding top cover open switch
- Top open switch
- Top closed switch
- 5 bow raised switch
- 5 bow lowered switch
• Tonneau release relay
• TONNEAU PULL DOWN ACTUATOR Fuse 20 A
• TONNEAU RELEASE Fuse 10 A
• BATT 2 Fuse 40 A
• REAR FOG/ALDL TOP SW Fuse 10 A
• Folding top mechanical components:
- Folding top
- Folding top cover
- Folding top valve 1
- Folding top valve 2
- Folding top valve 3
- Hydraulic lines and cylinders
Folding Top Cover Latch Actuator
The power folding top system includes a folding top cover that is powered open and close by a hydraulic system that is controlled by the FTC module. A power unlatch motor is used to unlatch the folding top cover before the folding top control (FTC) module powers the top cover open. The folding top cover unlatching is requested by the FTC module via class 2 message, but is executed by the body control module (BCM). When requested, the BCM applies battery voltage through the folding top cover release relay control circuit to the tonneau release relay. The relay is energized and battery voltage is applied through the folding top cover release control circuit to the latch actuator. The actuator is energized and the latch releases the folding top cover.
The electronics on this are very complex ,
System Operation
Before any movement of the power folding top is allowed, the folding top control (FTC) module must be aware of the following conditions:
• Unlatch the header. The FTC module reads the pin receiver switch is Inactive.
• The windows must be normalized. Refer to Power Window Reinitialization.
• The ignition must be placed in Accessory or RUN.
• The transmission must be placed in PARK, or with manual transmission, the park brake must be applied.
• Trunk status must not be ajar.
• The luggage barrier must be in place.
• The pump motor temperature must be within the operating range.
After the last cycle of power folding top operation, allow the hydraulic system a minimum of 4 minutes to bleed down before attempting manual operation of the top.

e-z one here: first release hydraulics (as per manual) in trunk by turning the screw counter clockwise on top of hydraulic pump available by a slit in trunk carpet- then pull top all the way back (open), then pull forward all the way to windshield- pulling lever to open top usually will now be used to latch clamps to windshield- then to open the top pull lever as usual, top will detach from windshield and you then pull it all the way down towards trunk- I could do it while sitting in driver\'s seat- I did this manually for many years, after tiring of fixing, then breaking, over and over- became very easy after a while, to open and close by hand
Down - undo zipper on one side about 12" just to take a little tension out
- undo latches - top down 2" - close latches (if you do not close them you are going to rip your top) - top down all the way, if you see a little circle and it is not folding just right, stop mid way and give it a light karate chop movement to help it fold properly *put the boot on for long drives, it will protect the top *store the car with the top up, it keep the material nice and properly stretched
Up - Windows down at least 75% - Top up and when it gets about 2" from being closed stop and open latches - Close rest of way, match up the pins and give it a little pull and snap the latches
No doubt your soft top issue has long been resolved but just in case someone has a similar issue:
I started to open my A4 Soft top externally using the door key method and like an idiot I must have disengaged the key before the soft top was fully down. I was unable to activate the opening or closing of the soft top automatically using either the key or soft top switch inside. I then manually closed the soft top using the users handbook and manual tool supplied. Soft top would still Not open automatically and the soft top alarm would activate. I solved the issue by manually opening the soft top fully and then manually closing the soft top fully. This seemed to have reset whatever had gone askew.
Run the top so the decklid opens, and down inside the top stow area there is a ~3" square access door for manual operation of the pump. Make sure the valve is tight!
I have seen many many 2008s that were never tightened enough from the factory.
Sounds like the sensor has faulted or the pump has become disengaged. Usually when the light is flashing it's a sensor. You can check for a pinched line or low fluid also. There is a manual lock overide procedure to get the windows up, it's in you owners manual. Good luck...i hope this helps,
you can change to manual operation by pulling the releasse lever under the l/r seat and this deactivate the moters the roof will open and close manual but you will have to comvert the rear lid when open to secuer the resar lid when the roof is open and this to hold it down.two ruber hold downs like you would use a a beash buggy bonnet
There should be latches you have to pull first to unlock the top from the windshield. Pull down the sun visors, the handles should be under them. Then push the power top switch.
