Tested Used Temic DQ381 Transmission ECU – TCM

The TCM Temic DQ381 is the electronic control unit dedicated to managing a dual-clutch automatic transmission from the Temic DQ range. It controls actuators and solenoids, orchestrates gear changes, manages clutches, and secures the system in case of anomalies. The part offered here is a tested used TCM Temic DQ381, provided as is and sold without prior coding for your vehicle. Depending on the configuration, this transmission ECU generally requires adaptation and/or programming after installation to function correctly. If needed, optional services (cloning, programming, pairing, immobilizer deactivation when applicable) can be ordered via the configurator, but they are not included by default.

Overview: Role of the Automatic Transmission ECU (TCM)

In a dual-clutch transmission from the Temic DQ family, the TCM Temic DQ381 is the brain of the gearbox. It processes real-time information from sensors (shaft speeds, temperatures, hydraulic pressure, selector position) and precisely controls the clutches and gear trains via solenoids. Its dual objective is to ensure smooth and protected gear selection and to preserve the mechanics by adapting the clutch and hydraulic pressure to the driving situation.

The TCM also manages safety strategies (limp mode activation, torque limitation, warning light on the instrument cluster) when it detects inconsistencies. In many dual-clutch transmissions, the TCM electronics are integrated into the mechatronic assembly, hence the importance of choosing a module from the correct family. The TCM Temic DQ381 belongs to the Temic DQ range and is intended for vehicles from the group using this specific 7-speed gearbox.

Your ECU at Incarline: Tested Used Part, Sold As Is, and Options If Needed

This TCM Temic DQ381 is a tested used part. It is provided as is and sold without any default coding, cloning, or pairing. A functional check is performed internally to verify electronic communication and basic parameters, then the part is prepared for shipment. Material compliance (reference, connectors, DQ381 family) must be validated by you before installation.

Depending on your vehicle's architecture, installing a TCM Temic DQ381 generally requires adaptation and/or programming to be recognized by the vehicle network and communicate correctly with the engine and other ECUs; this step may include pairing the module's identity, lifting manufacturer-specific component protections, or aligning software versions according to the car's needs.

If you wish to go further, OPTIONAL and PAID services are available via the configurator (e.g., cloning based on your old module when possible, programming/pairing for the provided reference, or interventions related to the immobilizer when applicable), orderable only if you choose to add them to your order. These operations are not included by default and do not automatically transform the part into a ready-to-install set; successful completion will depend notably on reference compatibility and the condition of the original unit if cloning is considered.

Our internal procedures aim to deliver a cleanly verified used TCM Temic DQ381 on its electronic aspect. However, the part remains a transmission electronic that will need to be integrated and adapted to the target vehicle by a professional with the appropriate diagnostic tools. Before purchasing, gather your original TCM references (DQ381 family, part number, HW/SW indices) and compare them meticulously with those presented to avoid any compatibility errors.
