I personally don't have much experience with this on our bmw's, however any connection could leak, only way to check is follow each line and look for oil build up at the connections.

To me the top while in movement seems a little slow and seems under powered, but that is normal.

Good Luck

Well, mine no longer opens if I don't help it along. It just keeps making the attemp but comes back down. I wonder if new gas shocks would help it any

Refer to my thread http://forum.e46fanatics.com/showthr...988&highlight=
I posted several PDF files which present information per your question.

Go to a pharmacy and buy a large syringe. I found topping up with a syringe very effective.

Read page 6.

and online repair manual LINK
E46 PAGE 6 DOES NOT SHOW YOU HOW TO FILL IT DIRECTSYOU TO A REPAIR MANUAL. iS IT POSSIBLE TO BE ON THE LOW MARK EVEN THOUGH YOU HAVE NO LEAKS? iS THERE A WAY TO MEASURE THE PRESSURE GENERATED BY THE PUMP TO SEE IF IT MEETS THE MINIMUM? mY TOP GOES UP AND DOWN COMPLETELY AS LONG AS I HELP IT ON THE START OF LOWERING AND RAISING THEN IT WILL COMPLETE THE CYCLE COMPLETELY BUT IT SEEMS SLOW. iTS LIKE THE LOWERING OR RAISING MOTOR DO NOT DEVELOP ENOUGH FORCE TO DE THE JOB.

gbaker, there is no info on how to fill the hydraulic reservoir on your link its all about a leak you have on the cylinder. Where is the info you posted on how to fill the hydraulic system??? Pics would be helpful.
Thanks!

DKUC,
WERE YOU TOLD BY A MECHANIC THAT THIS SLOW OPERATION IS NORMAL. I HAVE YOUR SAME PROBLEM EXCEPT I HAVE TO HELP THE LOWERING OR RAISING AT THE START. IT SEEMS I DON'T HAVE ENOUGH POWER ON THE MOTOR OR HYDRAULIC PRESSURE BECAUSE WNEN IT WAS WORKING IT NOT ONLY DID IT ALONE BUT MUCH FASTER. iTS SOMEWHERE AROUND 20 SECONDS LOWERING OR RAISING FOR A COMPLETE CYCLE.

If the operation is slow it's because the fluid is low.
If the fluid is low you have a leak somewhere.

You can fill the pump yet you're going to have to keep filling it unless you find and fix the leak.

Search for a DIY to change the pump, it also explains how to fill the pump. It's very easy once you have access to the pump. There is just one hex screw to remove to add or drain fluid. It looks like an oil drain plug.

Thumbs Up Refilling the hydro unit, fluid, pump rebuild, finding the leak

smellvetica,

indeed, the reason for the top moving slowly is usually a low fluid level. As taylor192 correctly states, you need to find the source of the leak if the fluid level is low. The fluid doesn't evaporate...

Here is the fluid management DIY that gbakerkingston posted a while ago:
http://forum.e46fanatics.com/attachm...1&d=1317591109.

Acceptable fluids outside of the overpriced BMW fluid are:
FeBi 02615 (same as BMW fluid, but much cheaper, for example at http://www.rmeuropean.com/Part-Numbe..._D18BD03A.aspx)
Mercedes fluid A0009899103 (same as FeBi and BMW fluid, also sometimes referenced as p/n 000989910310)
Pentosin CHF-11S (available in some parts stores)
Aral Vitamol ZH-M (in Europe)

There is also a good DIY on pump removal on the web. I cannot find it right now - hope somebody can place a link here.

If it were the bow tension cylinders that are leaking, then you would have already found the fluid dripping onto the tonneau cover. You could also have a main lift cylinder or a tonneau cover lift cylinder leaking, or one of the lines going to the cylinders. The lines we find to be damaged most frequently, are #23 going from the valve block near the left main lift cylinder to the right main lift cylinder (taylor192 wrote an awesome DIY for its replacement http://www.tophydraulicsinc.com/e46line23guide.pdf) and line 34 going to the left bow tension cylinder. The good news is, all of these parts can be replaced in DIY, and cylinder upgrades from Top Hydraulics are much cheaper and better than new parts from the dealer.

Top Hydraulics now manufactures all the small lines going to the cylinders, and we can even replace lines that are crimped onto the cylinders.

Lastly, the pump can burn out if it operates on low fluid for too long. Top Hydraulics also rebuilds convertible top hydraulic pumps (http://www.tophydraulicsinc.com/en/b...ulic-pump.html), but you want to avoid that expense...

Read the sticky about hydraulics. There is not a step by step guide specifically for the pump, yet all the info is there including detailed photos.

That and search, it's been covered many times.

NP.

Not to be rude, yet if you cannot figure it out from the pics in this post you should have a shop do it. I cover how to get access to the pump, free the pump, disconnect some hydraulic lines and the electrical connector. The only thing I didn't cover was how to drain and fill the pump since its just one plug that has to be removed.
