2019–2021 1.4T units are routine clones. The 1.5 TSI evo and the GLI are checked by label before payment.
The part-number prefix is the family-level part of the label (for example 06J 906 026 CK). A donor must match the full number, which we confirm against your VIN for free before you buy.
Clone the Jetta / GLI ECU — $350 flat
Mail your original and a donor with the same full part number. VIN, immobilizer data, coding and adaptations are copied across on the bench, typically within 24 hours of arrival. Factory immobilizer stays on.
Volkswagen engine ECU cloneOn-car software step — remote ODIS, $250
Some cars still want an on-car step after a module swap: a software version management (SVM) update, coding, or a basic-settings adaptation. Plug a J2534 pass-thru interface into the car and we run the factory ODIS software on it from our bench — no dealer visit. The same session covers coding after any other VW or Audi module replacement.

Which engine ECU does a 2019–2026 Jetta / GLI have?
It depends on the engine. The 1.4 TSI (2019–2021) (DGXA) runs Continental Simos / Bosch MED17 (by build), part-number prefix 04E 906 023 or 04E 907 309. The 1.5 TSI evo (2022–2026) (DPCA) runs Continental Simos 19 / Bosch MED17.1.27 (by build) — 05E-prefix label — the part-number prefix is confirmed from your label. The 2.0 TSI (GLI) (DNUA) runs Bosch MED17.5.25 / MG1 (by build) — the part-number prefix is confirmed from your label. The label on your module settles it in seconds.
Can you clone the ECU on a Jetta / GLI Mk7 (MQB A1)?
Yes, with a label check first. This generation runs the newest controllers; some read and clone on the bench, some need the on-car route. Text us the label and VIN and we tell you which before you pay. The clone is $350 flat.
Will a cloned Jetta / GLI ECU need dealer adaptation?
Usually not — it leaves the bench carrying your VIN, immobilizer data, coding and adaptations. If the car still asks for an on-car step, we run it remotely with ODIS over your J2534 interface for $250.
