2004 330ci Top Stops Half way Up

Greetings from Georgia ! (not usa

I have become a proud owner of BMW 330ci Convertible recently. All was fun and games until i started having a problem with the roof (

In the Video you can see what happens exactly.

I went over almost all threads regarding related issues, but can't seem to find the fix.

One more fact worth of mentioning is that Here in Tbilisi, Georgia there is literally no mechanic that specializes in Convertibles.

So unless i fix this myself, I am doomed to be opening and closing roof manually (


Should you have any suggestions or questions - please Ask !

You really need to know what the codes are from the CVM.

I use PA Soft 1.4. It includes a USB to OBDII Cable that allows you to read and change stored options as well as reading the error codes that are causing your top to not function.

I have PA Soft installed on an older Gateway Windows XP laptop but others have had success installing it on Windows 7 (I did not). I've even read some getting it to function in Windows 10.

Thx All2kool .

I will order that Cable.


Any other suggestions as how to work Blind without the codes ?


I did check the Level of the Fluid - it's ok.

I did inspect the Cable of the roof - outer black housing looks intact - so didn't rip it open - Can the cables be damaged even if outer housing is not ? Also what i did read on forums - if it's ripped cable - roof only opens a BIT and stops.

I didn't check the flapper motor - as i understood from different topics - if this malfunctions - your Lid doesn't shut / Open - right ?



What i do now if i want to have the tent open (and i really want to) - i initiate the opening sequence with the open button, after the Back Lid is UP i let button OFF, turn off the car - this way hydraulics seem to let it go also - So the roof is Movable by hands - i tuck it down the Boot, put Lid on - start the car (turn the key) - Push on the Closing Button and the lid closes - no problem.


Same goes backwards for the closing the roof.


So my problem is in the Middle of this process. I am open for any wild suggentions until i get the Cable to read codes from CVM.

It is very common for a failure to occur because of a bad wire in the bend point of the harness above the drivers side. My top failed to fully close one day and when I opened the harness, I found a GREEN wire to be severed. I soldered in a section of new wire and it's been fine ever since. See this video:



In this video, the user removes the retaining clip and is unable to reuse it - I found that it could slide down the harness with little effort. Do use a soldering iron to carefully open the harness - scissors will create a hack job mess.

Just curious, what is the best gauge wire to use when doing this repair?

Same size will work best. I had a piece of very flexible wire lying around that I used. I soldered in a section that was longer than what was needed - allowing for a bit of flexibility.

Bad News All2kool - i checked the wires in the Place you have shown in Video - and they all seem to look ok.


Will the Hydraulic liquid CHANGE do anything ? It is Leveled , But maybe because it is OLD - doesn't work well ?

At this point, you really need to know what the CVM Codes are. Temperature will be a factor too - if the hydro fluid is too hot, the top will not operate.

Thx All2kool. I will order V1.4 Diagnostic Scan Interface Scanner Programmer from Ebay.

That will take around a month to be delivered To Georgia. Will Replace the Fluid meanwhile.

PA Soft lets you read the CVM Codes so you'll know what is wrong. There are many sensors and components that make up the whole system. Once you know what is wrong, you'll know how to correct the problem. You can find part numbers when needed at Realoem.com.
