Checking the oil level in an automatic transmission
- 1 - screw plug,
- 2 - bypass (drain) pipe in the oil pan,
- 3 - cork (plug),
- 4 - safety cap
The transmission oil level in an automatic transmission depends on the temperature of the transmission oil. Since diagnostic equipment is required for accurate temperature measurement, it is recommended that this work be carried out by a VW workshop. Normally, the oil level in an automatic transmission stays constant unless there are visual leaks. In this case, there is no need to check the oil level.

Safety goggles must be worn when checking the level and changing the oil. A new screw plug seal and a new screw cap must also be installed.
Checking the oil level
When checking the level, the transmission oil temperature should be slightly below +35°C. This temperature is reached shortly after starting the engine. To determine the temperature, it is necessary to connect the VW diagnostic equipment to the connector. Otherwise, the temperature can only be determined approximately.
1. Place the vehicle on a lift in a horizontal position.
2. Remove the lower engine mudguard.
3. Set the automatic transmission selector lever to position "P" and apply the handbrake.
4. Start the engine while testing at idle speed.
5. At an automatic transmission temperature of +35 to +40°C, unscrew the screw plug (1) in the gearbox oil pan. The oil level is normal if there is a slight leakage of oil (conditionally due to the rise in the oil level when heated). Otherwise, add oil to the gearbox. Screw the plug back in until the temperature reaches +45°C and tighten it with a torque of 15 Nm.
6. Install the lower engine mudguard.
Change of oil
1. Place the vehicle on a lift in a horizontal position.
2. Remove the lower engine mudguard.
3. Install an appropriate container under the automatic transmission oil pan.
4. Unscrew the screw plug (1) checking the oil level, and then using a hex wrench and drain (bypass) pipe (2) from the oil pan (see fig. Checking the oil level in an automatic transmission). Wait until all the oil has drained from the gearbox.
Warning: Do not start or tow a vehicle without oil in an automatic transmission.
5. Screw in the drain (bypass) pipe (2) until it hits the oil pan.
6. Use a screwdriver to remove the safety cap located on the oil filler pipe, in this case it will be destroyed. Unscrew the plug.
7. First, pour 3.0 liters of fresh oil into the gearbox through the oil filler pipe.
8. Set the selector lever to position "P", start the engine and let it idle.
9. With the engine idling, apply the brake and move the selector lever to all positions (P, N, R, 3,2,1) with a delay in each position for 2-3 seconds.
10. Check the oil level in the gearbox and, if necessary, correct it.
11. At the required oil level, install the plug and close it with a safety cap.
12. Install the lower engine mudguard.

Checking the oil level in an automatic transmission
- 1 - bolt;
- 2 - threaded plug;
- 3 - oil;
- 4 - oil cap
The automatic 5-speed gearbox 01V does not provide for an oil change, and only the oil level is checked during maintenance.
Normally, the oil level in an automatic transmission stays constant unless there are visual leaks. In this case, there is no need to check the oil level.
Safety goggles must be worn when checking the oil level. A new screw plug seal must also be installed. To top up the oil, you must use a curved grease gun.
When checking the level, the transmission oil temperature should be slightly below +40°C. This temperature is reached shortly after starting the engine. To determine the temperature, it is necessary to connect the VW diagnostic equipment to the connector. Otherwise, the temperature can only be determined approximately.
Order of execution
1. Place the vehicle on a lift in a horizontal position.
2. Remove the lower engine mudguard.
3. Set the automatic transmission selector lever to position "P" and apply the handbrake.
4. Start the engine while testing at idle speed.
5. At an automatic transmission temperature of +35 to +40°C, unscrew the screw plug (2) in the gearbox oil pan (see fig. Checking the oil level in an automatic transmission). The oil level is normal if there is a slight leakage of oil (conditionally due to the rise in the oil level when heated).
Otherwise, add oil to the screw plug hole.
6. Pour in fresh oil with an oil can until it starts to come out of the screw plug hole (2).
Warning: Do not push the grease gun up as the oil seal (4) can jump off. Insert the tip of the oil filler into the side hole of the oil seal. Bolt (1) do not unscrew.
7. Screw in the stopper (2) into place until the temperature reaches +45°С and tighten it with a torque of 80 Nm.
Checking the condition of the oil
When checking the oil level in an automatic transmission, also check the condition of the oil. To make it easier to check the condition of the oil, compare the color, smell and viscosity of the oil with new oil.
If the gearbox oil is dark or almost black with a burnt smell, the gearbox friction linings are worn out.
If the oil in the gearbox is milky, it means that water has got into it. This can happen when the car is constantly used for short trips. If the color of the oil does not change after a long drive, the oil needs to be changed.
If the oil is dark brown and sticky, it may be because the transmission is overheated or the oil level in the transmission is too high. If an oil change fails, the vehicle must be taken to a VW specialist workshop.
If, when checking the oil level or changing the oil in the automatic transmission, there are dirt particles or metal chips in the oil, it is necessary to have the automatic transmission diagnosed or repaired at a specialized VW service station.
