| Inspecting the solenoid valves and shift elements while driving |
| The solenoid valves and shift elements can be inspected while driving in measured value block “08”, display group “004” ( → Chapter). |
| –
| Observe the safety instructions in → Chapter. |
| t
| The table indicates the activated solenoid valves -N88-, -N89- and -N92- in the individual gears. They control the position of the corresponding shift elements in the gears. |
| t
| Solenoid valve -N91- controls the modulation valve for the lockup clutch. |
| t
| Solenoid valves -N90- and -N93- are valves that influence gearshifting indirectly to offer great shifting comfort. -N90- = time delay valve, -N93- = main pressure valve (is not displayed in display group number 004). |
Note | t
| The display on vehicle system tester -V.A.G 1552- is 8-digit (e.g.: 01000011). |
| t
| Only consider positions 1, 3, 7 and 8. |
| l
| Selector lever in position “D” |
| l
| Vehicle speed higher than 10 km/h |
