The robotic seven-speed DSG7 DQ200 gearbox on the Skoda Octavia A7 once sucked the blood of owners. After 2014, engineers have perfected it, and official dealers replaced it under warranty. Today it is a quite serviceable and efficient mechanism, which is not inferior to the mechanics in terms of reliability. Provided that it is serviced in time. One of the conditions of DSG normal operation is oil change. Let’s find out how to change the oil in DSG 7 DQ200 gearbox and mechatronic control unit, what oil to use and how often to change it.
When to change the oil in DSG 7 in Skoda Octavia A7
DSG transmissions have their own specifics, but they work even faster than hydromechanical automatics. You just need to service them in time
Only original VAG G052512 A2 oil in a volume of 2 liters is suitable for replacement. For the Mechatronic block you also need only the original oil VAG G004 000 M2, one liter.

There are also alternatives. For example, the Mechatronic sometimes uses cheaper fluids:
FEBI 06161;
VAICO V600018;
PATRON ATFWS1L ORIGINAL;
SWAG 99906161.

There are several other options for replacing the original oil in the transmission:
FEBI 21829;
SWAG 10921829;
PATRON 75W90 GL5 ORIGIN.
If you can buy the original oil, it is better to do so. Original replacements are used only in extreme cases.
