VW DSG I DQ500 I Mechatronik ausbauen

Summary

This video documents the removal of the mechatronics unit from a 2016 VW Tiguan with a DQ500 DSG transmission. The owner reported intermittent transmission slipping, and a diagnostic scan showed a sporadic “Clutch Position Sensor 2 – Electrical Fault.” The presenter removes the unit so a specialist company can repair it.

Key Points and Procedure

• Access to the mechatronics unit is behind a transmission cover. The presenter found access on the Tiguan relatively straightforward—easier than similar work he had done on a Skoda Octavia.
• The process involves draining the transmission oil, moving wiring and brackets aside, disconnecting the ground cable and electrical connector, removing the cover, and undoing the mechatronics mounting screws.
• A plastic tube above the drain plug sets the transmission’s fluid level during filling from below. It uses an 8 mm Allen key and should be tightened gently by hand; overtightening could break it.
• The retaining clip around the connector and the cover should be replaced after removal.
• The unit contains sensor pickups, a circuit board, and solenoid valves. It is left to drain before being packed and sent for repair.
• The presenter emphasizes the importance of clean working practices when handling an automatic transmission control unit.

Observations and Concerns

• Ease of access: Better than expected on this Tiguan, though working space and camera positioning were awkward.
• Oil condition: The drained oil looked unusually dark to the presenter, despite the car showing about 95,000 km. He is considering a transmission flush after the mechatronics repair.
• Next step: The video covers removal only; reinstalling the unit is planned for a follow-up.

Verdict

This is a practical removal demonstration rather than a product review. The mechatronics unit is being sent to a specialist for repair; the video gives no repair outcome, product ratings, or numerical scores.

Speaker

• One presenter explains the fault, removal process, and his observations. He also asks viewers for feedback on the improved microphone sound.
