Tested used TCM Temic DQ200 transmission control unit – Temic DQ

The TCM Temic DQ200 is the electronic control unit that manages the 7-speed dual-clutch transmission of the Temic DQ family. Installed on the mechatronics, it controls the actuators, gear selection, and communication with the engine ECU. Incarline offers here a tested used part, sold as is, not coded for your vehicle. After installation, adaptation/coding is generally necessary to ensure operation and communication on your CAN network. Before purchase, check your exact reference (manufacturer label, version index) and compare the connector/format. If desired, OPTIONAL services (cloning data from the old TCM, coding/programming for your configuration) can be ordered via the configurator — they are not included by default.

Overview: role of the TCM transmission control unit

At the heart of a dual-clutch transmission, the automatic transmission control unit TCM orchestrates gear shifts, clutch management, and coordination with engine and chassis electronics. In the Temic DQ range, and particularly the TCM Temic DQ200, this unit monitors shaft speed sensors, temperatures, and actuator states, then applies shifting laws that optimize comfort and mechanical protection. It is an autonomous ECU that continuously communicates on the vehicle's multiplexed network.

The TCM Temic DQ200 is associated with the 7-speed dual-clutch 'dry' transmissions of the Temic DQ family. Once replaced, pairing/coding is generally required for the variant parameters (gearbox type, ratios, clutch calibration, vehicle-related functions) to be recognized. Without this adaptation step, the unit may remain in restricted mode and signal communication or configuration faults. This is expected behavior for this type of ECU and not a defect of the part.

Your ECU at Incarline: tested used part, sold as is

The unit offered is a tested used TCM Temic DQ200, provided raw and sold as is. It is not coded for your vehicle at the time of shipment. A functional check is performed to verify communications and basic electronic functions, then the part is prepared for dispatch. The warranty and exchange/return terms follow the applicable Incarline conditions for used parts; no specific duration or condition is promised here beyond these public conditions.

Important: this transmission control unit generally requires coding/adaptation after installation. Depending on the vehicle architecture, pairing or a configuration procedure may be necessary to lift limitations related to the variant. The responsibility for adaptation on the vehicle lies with you (garage, mechanic, or equipped individual). To secure your project, ensure that the reference, housing format, and connector type match your transmission model.

If you wish to go further, OPTIONAL and PAID services are available via the configurator (e.g., cloning data from your old TCM Temic DQ200 when technically possible, or coding/programming of variants) — these operations are not included in the part price. In any case, prior verification of the original reference remains the determining step for a successful replacement of your TCM Temic DQ200 from the Temic DQ family.
