Ongoing product quality tests and the analysis of our supplier identified a condition that may potentially
result in fluid seepage at the clutch actuator slave cylinder, that could result in an erratic operation of
the clutch. Therefore, we decided to preventively upgrade the vehicles involved and install an improved
clutch actuator slave piston kit.
