Transmission Fluid Level, Checking: Notes

Special tools and workshop equipment required 

• TOOLS FOR TRANSMISSION FLUID CHANGE 

Procedure 

Test Conditions

• Transmission not in emergency operation mode.
• Move the vehicle onto a four-column workshop hoist or over a work pit so it is completely level.
• Selector lever in "P".
• The parking brake button is pulled to activate the electro-mechanical parking brake.
• Suction hoses from an exhaust extracting system are connected.
• Engine running at idle.
• The A/C system and the heater are off.

Transmission Fluid Temperature, Reading 

• The transmission fluid level changes with the transmission fluid temperature: too low of a transmission fluid temperature leads to overfilling, and too high of a transmission fluid temperature leads to underfilling.
• An incorrect transmission fluid filling impairs the transmission function.
• The transmission fluid temperature must not be higher than 30 °C (86 F) when starting the procedure. Let the transmission cool down if necessary.
• Test temperature: 35 to 45 °C. (95 to 113 F)

-- Connect the Vehicle Diagnostic Tester -arrow- and identify the vehicle in Guided Functions  .

-- Select DSG Transmission  .

-- Select Check Fluid Level  .

• Specified value at beginning of test: not higher than 30 °C (86 F), otherwise let the transmission cool down.
