Replacing Hydraulic Fluid
I had a leak in the hydraulic roof latch. Now I need to add fluid to the reservoir in the trunk. I opened the lower allen key and the fluit won't go into the hole. I tried using a syringe and it did not work. Anyone know how to do it?

Not sure if this year works for your car.
No need to buy the MB tool. A normal syringe works to SLOWLY squirt fluid in using this method.

I was looking for an alternative than buying the specialized part. Actually, our dealership never even heard of it!

This did the job for me. It is a little slow, but did not make a mess.
