02E927770AN DQ250 Transmission Control Module

The 02E927770AN control module is for the DQ250 / 02E six-speed dual-clutch transmission family. Retain the AN suffix when comparing the original controller number.

Include the hardware identification and vehicle transmission code with your enquiry. The connector and physical layout should be checked together with the software and coding requirements.

Send the original module label, vehicle VIN, transmission code and required quantity. Include the workshop’s coding or programming requirements in the enquiry.

The 02E927770AN is a transmission control module for the DQ250 (02E) six-speed wet dual-clutch transmission. It is the electronic control unit that reads the transmission sensor inputs, including input and output shaft speed, selector position, oil temperature and clutch position, and then commands the electrohydraulic mechatronic unit that engages the two clutches and selects the gear pairs. On the DQ250 wet dual-clutch gearbox the control module is integrated with the hydraulic actuator block in the mechatronic assembly, so this reference identifies the electronics and control side of that unit. The full reference number, including the AN suffix, identifies the controller variant, and the module carries the shift software and adaptation data that must correspond to the transmission it is fitted to.

• Component: Transmission control module (TCU) for the DQ250 / 02E transmission
• Transmission family: DQ250 / 02E
• Transmission type: six-speed wet dual-clutch
• Reference number: 02E927770AN — the AN suffix is part of the identification
• Role in the system: reads transmission sensor data and controls clutch engagement and gear selection through the mechatronic unit

The 02E927770AN control module is specified for vehicles running the DQ250 (02E) six-speed dual-clutch transmission, a wet-clutch unit used across Volkswagen Group applications. The DQ250 was built in several hardware and software versions over its production life, and the controller reference ends in a letter code that distinguishes those variants, so the module must be matched to the transmission by part number and hardware version rather than by vehicle model alone. The AN suffix is significant: controllers that share the 02E927770 base number but carry a different final letter are not interchangeable in every application. Confirm the number on the original module, the hardware identification and the transmission code before ordering, and check the connector and physical layout against the removed unit.

• Transmission family to match: DQ250 / 02E
• Transmission type to match: six-speed wet dual-clutch
• Primary check: the complete controller number on the original module label, including the AN suffix
• Secondary checks: hardware identification, transmission code, connector pattern and physical layout against your original unit
• Workshop planning: include the vehicle VIN and any coding or programming requirement in the enquiry

The 02E927770AN transmission control module is supplied as a new component. TOSEN sources DQ250 electronics through a factory-direct supply channel and checks units against the reference number and connector arrangement described on this page before dispatch, so that the variant supplied corresponds to the controller number stated in the order. Distributors and repair workshops building a stock profile for the DQ250 family can request a sample unit so the hardware version is confirmed against the original before a larger order is placed.

What transmission does the 02E927770AN control module fit?

The 02E927770AN is a transmission control module for the DQ250 (02E) six-speed wet dual-clutch transmission, a unit used across Volkswagen Group vehicles. Confirm that the complete number on your original module matches 02E927770AN, including the AN suffix, and that your gearbox is a DQ250 before ordering a replacement control module.

Is the AN suffix important when ordering this module?

Yes. On the 02E927770 controller the final letter code distinguishes the controller variant, and modules that share the same base number but end in a different letter are not interchangeable in every application. Read the complete string printed on the original module and quote it in full, including the AN suffix, so that the replacement supplied carries the correct hardware and software identification for the transmission.

Does a replacement DQ250 control module need coding?

A replacement transmission control module for the DQ250 generally needs coding or adaptation to the vehicle after installation, because the module carries shift software and adaptation data that must match the transmission and vehicle configuration. Send TOSEN the original module label, the vehicle VIN and your workshop’s programming requirements when enquiring, so the scope of the installation work is clear before the module is dispatched.

How do I confirm the correct 02E controller before ordering?

First read the reference number on the original transmission control module and confirm the complete string, including the suffix, matches 02E927770AN for a DQ250 gearbox. Then compare the electrical connector and physical layout against your removed unit, and supply TOSEN with the module label, the transmission code and the vehicle details so the part can be verified before you commit to the order.
