The automatic transmission control unit (often designated as TCU or TCM) is a crucial electronic component responsible for smooth and trouble-free gear shifting. Its failure, most often caused by overheating, short circuits, or water damage, results in jerking, an inability to shift gears, or the vehicle entering limp mode. Purchasing a new module at an authorized dealership is a massive expense, which is why replacing it with a fully functional, used original is the most reasonable solution.

Important: Depending on the ECU type and vehicle model, not all of the options listed below may be available.
To select the correct option for your vehicle and ECU, please contact us before purchasing:
contact@auto24parts.com
1. Locked
This option is intended for professional workshops with the required specialist equipment and technical knowledge.
The ECU has been removed from a vehicle intended for recycling and still contains the immobilizer data and other information from the previous vehicle. Before it can be used in another car, it must be unlocked and then programmed using specialist automotive diagnostic equipment.
2. Unlocked
Several preparation methods may be available. The possible options depend on the ECU type, vehicle model and immobilizer system. Please contact us before purchasing, as some preparation methods are not available for every ECU.
Our electronics specialists can prepare the ECU in one of the following ways:
a) ECU with PIN code (Car Pass)
The PIN code is supplied, but programming with a suitable diagnostic tool is still required. After installing the ECU, it must be reset using the supplied PIN code and then programmed to the vehicle’s immobilizer system.
b) VIRGIN ECU
The data from the previous vehicle is removed and the ECU is restored to a clean, factory-like state. After installation, it must be programmed to the vehicle using a compatible specialist diagnostic tool. Unless another preparation method is specified in the product description, this is the standard unlocking option for most of our ECUs.
c) Plug & Play – IMMO OFF
The immobilizer function is disabled in the ECU. After installation, the engine can start without additional immobilizer programming. Please note that the vehicle will no longer have an active immobilizer function, and an immobilizer warning light or fault code may remain, depending on the vehicle model.
d) Plug & Play – Automatic Programming
After installation, the ECU automatically learns and saves the required vehicle data. No additional programming is normally required.
e) Plug & Play – 1:1 Clone
The data from your original ECU is copied to another fully functional ECU. The cloned unit is then ready for installation without additional programming.
You must send us your original ECU so that we can transfer its data to the replacement unit.
The original ECU must have working communication with the vehicle, a diagnostic tool or our programming equipment. If the required data cannot be read, a complete 1:1 clone may not be possible.
3. Complete Plug & Play Set
A complete matched set containing the ECU, immobilizer components and all other parts required to start the vehicle without additional programming. All components supplied in the set must be installed in the vehicle.
Important:
Dispatch time depends on the selected option. If an unlocked or specially prepared version is ordered, the preparation service usually requires an additional 1–2 business days.

Does ECU 03L906023MA fit the Tiguan 2.0 TDI?
It does if your module has VW number 03L906023MA and Continental number 5WP42904 AA. This is a used, working PCR2.1 ECU from a Volkswagen Tiguan 2.0 TDI, with the additional number 03L907425B on the label.
Engine Control Unit Volkswagen Tiguan 2.0 TDI Continental PCR2.1 03L906023MA 5WP42904AA 03L907425B
The Volkswagen Tiguan with the 2.0 TDI engine uses a Continental ECU from the PCR2.1 family – one of the Simos variants designed for diesel engines. The VW part number of this unit is 03L906023MA, and manufacturer number 5WP42904AA belongs to the Siemens VDO / Continental numbering system. The module controls the common rail injection and the running of the engine. We offer it used, in working order and in good condition.
Numbers to compare
- 03L906023MA – VW part number
- 5WP42904AA – Continental number, on the label 5WP42904 AA
- 03L907425B – second VW number visible on this ECU
- PCR2.1 – ECU family
The MA suffix in number 03L906023MA denotes the software and hardware version. There are many versions in the 03L906023 family, so compare the full number and, if in doubt, the second VW number as well.
Symptoms of failure in the Tiguan 2.0 TDI
- the engine will not start despite a working starter motor,
- no communication with the ECU during diagnostics,
- reduced power and an engine fault warning,
- internal module faults that cannot be cleared.
Before deciding to replace it, check the power supply, earths and the condition of the connector – these are the most common causes of similar symptoms.
Locked or unlocked PCR2.1 ECU
The unlocked version is a module we prepare before dispatch – this usually takes 1–2 working days. The locked version contains the data and immobiliser of the Tiguan it came from and is aimed at workshops that unlock, program and match ECUs themselves.
Not every method (PIN / CAR PASS, Virgin, IMMO OFF, auto programming, cloning) can be used on every ECU – it depends on the number, software and immobiliser. Please ask before buying. You will find a description on the ECU preparation options page.
