Temic TCM Temic DQ380 ECU tested and guaranteed

The TCM Temic DQ380 is the automatic transmission ECU that controls a dual-clutch transmission from the Temic DQ family. INCARLINE offers here a tested used part, sold as-is, from a rigorous quality control. By nature, this type of ECU generally requires adaptation or programming after installation to function correctly in your vehicle. It is not provided cloned, coded, or paired by default. If you need cloning, programming, or immobilizer deactivation, these operations are available as optional paid services via the configurator, but are never included automatically. Before purchasing, check the exact reference and hardware/software index on your unit's label to order a compatible Temic DQ380.

Overview: role of the automatic transmission ECU (TCM)

The automatic transmission ECU, or TCM (Transmission Control Module), coordinates all actions related to gear shifting and clutch management on a controlled transmission. In the case of a Temic DQ family unit, it controls electro-hydraulic actuators, measures pressures, monitors temperatures, and adjusts shifting strategies in real-time to balance comfort, reliability, and consumption. The TCM communicates over a network with other vehicle ECUs (engine, ABS/ESP, powertrain management) to adapt shifting laws and transmitted torques. A correctly identified and integrated TCM allows for precise gear selection and stable coordination between engine and transmission.

The Temic DQ380 is part of the Temic DQ range of TCMs, frequently associated with 7-speed dual-clutch transmissions within vehicles from the same industrial group. Like any modern ECU, it relies on a 32-bit microcontroller, calibration memory, and power stages dedicated to control solenoids. Pressure balancing, clutch learning, and information exchange via the communication bus are among its key functions. When replacing, ensure the ordered unit matches the information on your original TCM to avoid any hardware or software incompatibility.

Your ECU at Incarline: tested used part, sold as-is, with quality control and warranty

INCARLINE provides a tested used TCM Temic DQ380, bench-tested and controlled according to an internal procedure focused on power supply, communication, and basic commands. The part is sold as-is: it is not a cloned or programmed unit by default, and it is not supplied paired with your vehicle. Each ECU is checked before shipment and benefits from an Incarline commercial warranty, the terms of which are available on our usual platforms. The goal: to provide you with a sound and functional base to replace your faulty TCM with confidence.

Upon receipt, adaptation/programming is generally required for the TCM Temic DQ380 to function correctly in your car; this step may include coding, variant configuration, and/or learning. For customers who wish, OPTIONAL PAID SERVICES (such as cloning, programming, immobilizer deactivation, or standard exchange) can be added via the configurator during the order, but they are never included automatically.

Carefully packaged, the unit is protected against shocks and static electricity. Before any intervention, disconnect the vehicle's power supply and observe the usual precautions on embedded electronic systems. In case of doubt about compatibility, prioritize verification by references and connectors, rather than by the simple appearance of the casing. This approach limits the risk of incompatibility between close variants within the Temic DQ family.
