Every 40,000 miles your DSG will require fluid and filter changes.
The most common DSG variants have their clutches submerged in gear oil that both lubricates and cools the unit down. The fluid also catches material that is shed from the clutch plates over time. These are filtered out, but just as your car’s oil filter, air filter and other filters get clogged, so too will this one.

The complexity and apparent expense of the DSG can lead some to put off routine maintenance for fears that the maintenance costs will get out of control. However, the benefits of servicing your DSG are:

• Saving money on costly gearbox repairs.
• Improving your car's performance.
• Ensuring the manufacturer's warranty remains valid for the gearbox and mechatronics.
