Hey guys

Recently picked up a 2010 Z4 sdrive35i.

I had purchased the car with the top being non functional. The seller said bmw told him it needed a new top and they couldn't figure out what was going on after a leak....after the leak was fixed.

Good news is the pump is fully functional....Long story short i purchased full left and right mechanisms with hydraulics cylinders and everything.

This is what happens:

Step 1: Windows roll down
Step 2: Back shell folds on front shell
Step 3: Trunk opens
Step 4: Front shell unlocks

Step 5 (Faulty step): Front shell comes off the windscreen crooked every time and almost always the left comes off the first then the right side.

Now to correct this I have done the following:
-Replaced passenger side hydraulic in the trunk
-Left side arm that was bent on visual inspection

This has not fixed my problem and the roof still comes off crooked as before. I plan to do the driver side hydraulic next.

Side note: I can stop pressing the button at step 4 and manually lift the top and fold it down with it catching anywhere so that tell me it has to be the hydraulics some where....am I right?

Any suggestions on what to attack next?

Also how do you read roof codes? I have Carly pro but it does no seem to show me any codes. Should I be using some thing else ?

I'm fairly new to bmw...always been a Audi guy
