| Inspect | ||
1 | Fill compressed-air circuit of air suspension completely | ||
2 | Check solenoid valve of front axle electronic level adjustment (Y11), solenoid valve block of rear axle level adjustment(Y12) and their connections for leaks | Use commercially available leak detecting spray or soap suds. Check components and connections for bubbles. In the event of leaks, seal or replace the appropriate component. | |
3 | Check all pressure lines and their connections to the front air spring bellows (1), rear air spring bellows (2), the air chambers (3) the reservoirs (4) for leaks | Use commercially available leak detecting spray or soap suds. Check components and connections for bubbles. In the event of leaks, seal or replace the appropriate component. | |
4 | Check front air spring bellows (1), rear air spring bellows (2), reservoir (4) and air chambers (3) for leaks | Use commercially available leak detecting spray or soap suds. Check components for bubbles In the event of leaks, seal or replace the appropriate component. | |
5 | Check pressure limiting valve (5) for leaks | Use commercially available leak detecting spray or soap suds. Check pressure limiting valve (5) for bubbles. In the event of leaks, replace pressure limiting valve (5). |
