02E927770AJ DQ250 Transmission Control Module

This DQ250 control-module product is identified by 02E927770AJ. It is a transmission electronics component for the 02E dual-clutch family.

For a controller replacement, compare the complete label and hardware layout with the removed unit. Include any accompanying valve-body requirements separately in the enquiry so the supply scope is clear.

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

The 02E927770AJ is a transmission control module for the DQ250 (02E) six-speed wet dual-clutch transmission, supplied as the electronics component of the mechatronic assembly. It reads the transmission sensor inputs, including input and output shaft speed, selector position, oil temperature and clutch position, and then commands the electrohydraulic unit that engages the two wet clutches and selects the gear pairs. In this listing the controller is treated as part of a mechatronic replacement scope, so the order can cover the electronic controller together with the hydraulic actuator block where the repair requires the complete assembly. The full reference number, including the AJ suffix, identifies the controller variant, and the module carries the shift software and adaptation data for the transmission it is matched to.

• Component: Transmission control module (TCU) for the DQ250 / 02E transmission
• Transmission family: DQ250 / 02E
• Transmission type: six-speed wet dual-clutch
• Reference number: 02E927770AJ — the AJ suffix is part of the identification
• Role in the system: reads transmission sensor data and controls clutch engagement and gear selection; can be supplied with the valve body where a mechatronic repair requires it

The 02E927770AJ control module is specified for vehicles running the DQ250 (02E) six-speed dual-clutch transmission. Because the DQ250 was built in several hardware and software versions, and the controller reference ends in a letter code that distinguishes those variants, the module must be matched to the transmission by part number rather than by vehicle model alone. The AJ suffix is significant: controllers sharing the 02E927770 base number but ending in a different letter are not interchangeable in every application. When the repair covers a complete mechatronic or valve-body assembly, the hydraulic scope should be specified separately in the enquiry so that the electronics and hydraulics are matched together. Compare the complete label, the hardware layout and the connector pattern against the removed unit before ordering.

• 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 AJ suffix
• Secondary checks: hardware layout, connector pattern and any accompanying valve-body requirement against your original unit
• Workshop planning: include the vehicle VIN and any coding or programming requirement in the enquiry

The 02E927770AJ transmission control module is supplied as a new component and can be ordered as part of a wider mechatronic scope. TOSEN sources DQ250 electronics and hydraulics through a factory-direct supply channel and checks each unit 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 can request a sample unit so that the hardware version is confirmed against the original before a larger order is placed, and the accompanying valve-body requirement can be quoted separately so that the supply scope is clear.

What transmission does the 02E927770AJ control module fit?

The 02E927770AJ 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 02E927770AJ, including the AJ suffix, and that your gearbox is a DQ250 before ordering a replacement control module.

Is the AJ 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 AJ suffix, so that the replacement supplied carries the correct hardware and software identification for the transmission.

Can I order the controller together with the valve body?

Yes. Where the repair covers a complete mechatronic or valve-body assembly, the 02E927770AJ controller can be supplied together with the hydraulic unit, and the valve-body requirement should be stated separately in the enquiry so that the electronics and hydraulics are matched together. Include the complete label and hardware layout of the removed unit so that both parts are confirmed against the original before ordering.

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 02E927770AJ for a DQ250 gearbox. Then compare the electrical connector and hardware layout against your removed unit, and supply TOSEN with the module label, the transmission code and the vehicle details so that the part can be verified before you commit to the order.
