Mein Auto: 323ci
Convertible Hydraulic Leak

2000 BMW 323ci

My convertible top stopped working a few month's back. With summer approaching I decided it's about time to see if I can fix it myself. When I begin to retract the top, the widows roll down, the top unlatches and I can hear the pump operating. But the top does not retract. I removed the trunk liner and noticed there was very little fluid left in the hydraulic pump and found a small puddle of hydraulic fluid running down the left side of the trunk from behind a small metal plate attached by three bolts.

I removed the bolts and the metal piece to find a 6" long cylinder that appears to be leaking the hydraulic fluid. I took my car to the dealership and asked for them to replace the part. They came back and said it would cost $3,200 to repair as all my hydraulic lines were leaking. I was shocked! I'm not convinced they even looked at the problem and instead quoted me to replace the whole damn thing. I tore apart the entire trunk and found no other leaking hydraulic lines.

So my question is.... is it difficult to replace this small cylinder? Is this a DIY project? I think it's worth a shot to see if I can get a few more uses out of my convertible top if I can replace the part for a few hundred bucks (or less). Can anyone provide recommendation on how this can be done? I couldn't tell from looking at the part how to remove it.

Thanks in advance!

Check here and see if you can identify the part in question.

A pic or two from your car might help....

I'd find a wrecker and buy the entire top from a 2005/6. It takes about an hour to swap tops. Top Hydraulics will refurbish all cylinders and replace your lines for a lot cheaper than BMW! I doubt it is your pump, as the system is only pressurize when the pump is operating, so if it is leaking in the system, the pump is creating pressure.

Convertible top work is time consuming and finicky

$300 more to ship - it is a perfect solution. Make certain that they disconnect at the connectors in the storage area and include mounting brackets and hydraulic control block.
