2001 SLK230 Vario Roof Code B1270 - Roof Opens Faster Than Trunk After Cylinder Rebuild

Model: 2001 SLK230 Vario Fault Code: B1270 Posted: 2015-08-03 15:32

After sending the cylinders for rebuilding, my 2001 SLK230 Vario is now acting like it's out of time. The roof opens significantly faster than the trunk. I did not disassemble the system myself, so I'm unsure if the original installation was correct. Any insights into whether this could be related to the B1270 fault code or a mechanical misalignment after cylinder rebuild?

The issue might not just be with the trunk cylinders—my switch operates in reverse. Any suggestions on how to fix this or verify proper wiring?

It's possible that oil lines were connected incorrectly during assembly, which could lead to improper operation and trigger fault code B127或 mechanical timing issues.
