Assuming the W116 is like the W123, there is no electric "stop" for the motor when the window reaches full up or full down. This causes the motor to keep twisting then the window can no longer move. This twisting transfers to the regulator and over time bends it...and then people keep using the window in this state without fixing it and wear off the teeth or actually crack the regulator.
Additionally, the regulators go without lubrication and people keep using them despite their slow operation. This leads to wear on the teeth and bending as well.
This is why every original regulator on every W123 I've touched is bent. It's just inherent, it seems.
None of this applies to the manual regulator. Therefore they last longer...
