General Information

WARNING: This page is about a different car, the 2015 Audi Q5, 2014 Audi Q5, and 2013 Audi Q5. However, it is still accessible from the selected car via links, so may be relevant.

Transmission

The 8 speed automatic transmission 0BW hybrid has 8 hydraulically controlled forward gears.
The 8 speed automatic 0BW hybrid AWD has NO torque converter. An Electro-Drive Drive Motor -V141- is installed instead.
Acceleration in 1st gear is controlled with the B clutch in the transmission. This is also known as "drive clutch B".
The decoupler in Electro-Drive Drive Motor -V141- separates the internal combustion engine from the Electro-Drive Drive Motor -V141-. The decoupler is also described as "decoupler F" or just "clutch F".

Mechatronic

The Mechatronic combines the following components as a complete synchronized unit:

Transmission Control Module -J217- hydraulic control
The sensors and actuators

The Mechatronic unit is installed in the transmission in the area of the ATF pan.

Transmission Control Module -J217-

The control module is part of the Mechatronic unit in the transmission.

Determining the driving situation and driving resistance dependent shift point occurs automatically.

Advantages:

Usage-based shifting
Maximum engine output is always available
Individual adaptation of shift points in all driving situations
Gear shift points are infinitely variable

On Board Diagnostics (OBD)

Use "Guided Fault Finding " to determine the exact cause of damage before servicing the automatic transmission.

Use the Vehicle Diagnostic Tester to perform "Guided Fault Finding "

Shift Point Changes on Inclines and Declines

When driving on inclines or declines, gears are automatically selected using additional shift characteristic maps. The selection is based on accelerator pedal position and vehicle speed.

The gear change map for extreme uphill stretches is matched to engine output
The gear change map for extreme downhill stretches is matched to the braking effect of the engine.
By selecting a gear directly using tiptronic, the driver can use the engine braking effect with a specific gear engaged, for example when driving downhill with a trailer.
