A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

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.

Looking for a Simos PPD1.2 03G906018EH ECU for the Touran 2.0 TDI?
This is a used, working Siemens module with VW number 03G906018EH and manufacturer number 5WP45565 AC, taken from a Volkswagen Touran 2.0 TDI. Available in a locked or unlocked version.
Engine Control Unit Volkswagen Touran 2.0 TDI Siemens Simos PPD1.2 03G906018EH 5WP45565AC
The Simos PPD1.2 is a Siemens ECU designed for diesel engines – unlike most Simos ECUs, which handle petrol engines. This unit comes from a Volkswagen Touran 2.0 TDI and has VW part number 03G906018EH and manufacturer number 5WP45565AC from the Siemens VDO / Continental numbering system. The module controls injection and the running of the engine. It is used, in working order and in good condition.
Numbers to compare
- 03G906018EH – VW part number
- 5WP45565AC – Siemens number, on the label 5WP45565 AC
- Simos PPD1.2 – ECU family
The letters EH at the end of the VW number denote the software and hardware version. 03G906018 ECUs with other suffixes are not always interchangeable.
Symptoms of a faulty Simos PPD1.2
- the 2.0 TDI engine will not start despite a good power supply,
- no communication with the module during diagnostics,
- limp mode and reduced power,
- injector control faults with no fault in the injectors themselves.
Check the wiring loom, earths and connector first – only then suspect the ECU itself.
Which ECU option to choose
If you have access to a workshop that unlocks, programs and matches ECUs itself, choose the locked version – it will arrive with the data and immobiliser of the previous Touran. We will prepare the unlocked version before dispatch; this usually takes 1–2 working days.
For the Simos PPD1.2, as for any ECU, the availability of PIN / CAR PASS, Virgin, IMMO OFF, auto programming and cloning depends on the number, software and immobiliser. Please ask before buying. Description: ECU preparation options.
