There is also an observation window on the housing of Autoflug belt tensioners, through which 2 cables are visible. Autoflug belt tensioners where
only 1 cable or no cable is visible, have been triggered and must be renewed.
Autoflug belt tensioners have always been equipped with an approx. 80 mm shorter tube than the Repa belt tensioners. Repa belt tensioners also
incorporate this shorter version of tube as of 01/88.
