Thanks, I actually just fixed it.

Bought the Mercedes ZH-M oil, mainly because my local MB dealership stocked it. Tried BMW first but they didn't even have it in stock.
Filled it up and now the top goes super fast!

I contacted Top Hydraulic in Florence Or. My symptoms were that I had to assist manually the open and close sequence while holding the appropriate button. Ordered the hydraulic pump from them replaced and now the top works ***128175;% automatic. No need to manually assist the open/close sequence. The culprit was a weak pump.

In theory the line could be run along the forward edge of the storage area. Either tuck the line under the weather striping or secure the line with some double-sided tape clamps.

I'll update the original post with these ideas. Hopefully the next person can document it.

Oh, could you please delete your triple posts. Thanks!
Looks like my line 23 is shot so Iím ordering extended version. I swear I read somewhere to replace 23 and 24 together but canít find that again. Thoughts on this?

Iím really thinking of running it along the back seat like the posts above pointed out or in the forward edge of the storeage area. Iíll document with pictures which way I go. Any reason I couldnít run 23 and 24 both through one of these methods???

No need to replace both of you buy a single line from Top Hydraulics. The only reason to replaced both is if you buy the OEM lines which are sold as a pair.

Looking forward to someone trying the routing along the forward edge of the storage compartment... Although it doesn't save that much effort, most of the steps are still required.

I just replaced my line 23 with the extended version. I ordered line 24 with it but didn't replace as only 23 was leaking at the bend.

I didn't remove 23, rather plugged the ends and left where it was basically. I removed everything in the back and in the trunk in order to determine the best way to run the line (without going through the roof). Running it along the back seat would have worked (like someone else posted). Instead I opted for running it along the bottom lowest points possible in the storage area (against the wall/side of the back seat). I taped it down. I went this route because I could periodically check on it when the top goes up or down and it seemed to provide a route away from the hinge parts.

I had no idea how I was going to run that line through the roof - it looked harder than it might actually be, BUT running it through the top storage area was VERY easy. The hardest thing was playing with it to make sure it wasn't landing in an area around the hinges that would pinch it.

2 hours to disassemble everything (again I did way more than needed) and 3 hours to run the line and refill the pump with the help of my wife with an hour of reinstall and clean up. Removing the clip on the passenger side that holds line 23 was a pain! Found out moving the top back just about 1/3 of the way provided great access. Of course didn't think of this until trying for about 30 min.

As a side note, I don't see how it would be possible to do line 24 without removing/lifting the top. Hopefully I won't have to find out.

Big thanks to everyone who helped with these threads!

My Ride: 2004 BMW 330Ci
Need help. Read through the forum and I'm lost. I have 2004 bmw 330ci convertible. Here are my issues and problems. First off thank you the the members and great write ups. I was able to reinforce laches so my roof now locks and closes at the windshield. But I have 10 more problems.
When I press open button roof goes up maybe two inches and stops. Rear part of windshield is trying to move but it quits and red light start blinking. Then I manually help raise the back windshield and convertible storage lid starts lifting but it won't go all the way up. I took four nuts holding cover to hitches and hitches with out cover go up no problem. ( there is slight delay between right hitch going up). Then the roof goes down to the compartment and hitches are going down.

To raise roof it's same thing like opening only in reverse. Roof at the windshield goes up maybe an inch and error (So I manually lift it). Storage department cover tries to go up but it want all the way up. With out plastic cover hitches are going up all the way. Then rear windshield goes down but it self and rest of the roof is closing and latching in place.
Also I'm attaching errors. First picture with code 11 happened today. Second one yesterday and the third on yes you guess it 2 days ago.
Any help would help. Thanks guys and gals.

pump vs valve block

After reading so very much to read!! Symptoms of top moving slowly to requiring intervention. Mine has done both and now requires manual intervention The valve block symptom says when going bad the top moves slowly. When the hydraulic pump is going bad the top normally stops half way and requires assistance. That valve cost almost the same as the pump. Is there any way of knowing for sure which is the real problem?

Start with the pump, it is far more likely to be the problem. Even if it's not, since these cars are >12yo your pump is probably due soon anyways.

The Pentosin CHF-11S can be bought at a Napa store for about $21. Even though it says power steering fluid, it s the one that is mentioned on here. Also, the guys at napa said its the same fluid for the hydraulic pump. So, anyway, was wondering if there is a special way of draining the fluid and replacing it. I dont want to go crazy and disassemble the whole pump.

Taylor192... this is one great post and replies. Thanks for your help. Big gap between last post and this one, but will try anyway.
Mine is a 2004 330CI vert. Roof starts ok as it disengages at front. Stops a few inches from the windshield, but pump keeps humming with increasing loudness until it stops, red light blinking. At this point I can complete the storing of roof manually, but to latch the back cover, I press button for a few more seconds until light stops blinking. I sense pump has not enough force. No leaks detected anywhere, fluid level ok.
So, question is... is it the pump? Does sending it to Top Hydraulics for rebuilding internals likely fix problem?
Could it be electric... a cable... the pump relay?
Your help would be greatly appreciated.
Thanks in advance.

Checked hydraulic fluid level and it is over the normal mark, but I have never topped off. Canít see any leaks anywhere.
Help is appreciated.
