Check

6

Check suspension strut pressure line connection (40a) on front suspension struts (40) using leakage spray for leaktightness

MODEL 212
with CODE 489 (AIRMATIC)

 Wait for approximately 10 to 15 minutes after spraying the leakage detection spray. This allows smaller leaks to be detected (bubbles form). Larger leaks are visible immediately.

In the event of leaks:



Repair affected suspension strut pressure line connection (40a).
