Cabrio top problems

Tried to close the top last week after pulling off the hard top. It closed fine but when we opened it the clamshell would not open. Rear latch was stuck. Opened the lid manually and lubricated the cables and gears/racks with WD-40. Found that the hyd res was bone dry and added Mercedes hyd fluid, which was all we could find in a pinch. Everything seemed fine for a minute - the top closed the rest of the way and the clamshell closed and latched. When we tried to open the top the clamshell opened and the top moved about half way. The it started clicking and barely moving with each click. After about 20 seconds all movements and sound stopped. Where do we start? This all started because the dealer got an ECM fault p0448 and wanted $7,000 to fix it...

Did you check the res again? Sounds like you may have a blown piston seal.

You need to find out where the hydr. leak is. If the leak is substantial enough, and has once again become too low to allow the cylinders to operate normally, then you must address this issue first.

It is unlikely that the Evap code diagnosis performed by the dealer has anything to do with your loss of hydr. fluid. You should be able to find the leak yourself, it will just involve some looking for the wet component.

Take some pictures of what you find and post back. I am sure members will be able to walk you through testing/removal/
