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.

Engine control unit for Porsche
If your Porsche is hard to start, loses power or has the engine warning light on, the control unit may be the cause. We are selling a used module in working order and in good condition.
How this control unit is labelled
- 5WP46543 05 / 5WP4654305 - manufacturer's number (Continental)
- 97061860103 - OEM / vehicle number
- 6576665313 - another number from the listing
According to the listing data: Porsche (model), Continental (manufacturer).
Locked and unlocked variants
A locked control unit is sold with the previous vehicle's data - this is an option for workshops that can unlock and program it. We prepare an unlocked control unit before dispatch (approx. 1-2 working days), so you do not have to do it yourself. The unlocking options depend on the number, software and immobiliser - not every method (PIN / CAR PASS, Virgin, IMMO OFF, auto-programming, cloning) works on every control unit. You will find details here: locked versus unlocked engine control units. We are also happy to answer any questions before you buy.
How an engine control unit works
The same car model may have had several control unit versions, depending on the engine, power output and year. The numbers in the list let you tell these versions apart. Damage can result from water ingress, a voltage surge or wear of the electronic components, and it can show up intermittently.
How to match this part
Our range also includes other control units for this model and engine, with different numbers. Choose by the number on the module, not by the model alone. If in doubt, send us the number from the label or a photo of the module and we will check the fit before you buy.
Symptoms of a faulty control unit
- the engine jerks and loses power,
- the idle speed is unstable,
- the diagnostic tester shows a control unit or power supply fault,
- fuel consumption increases.
It is worth reading the fault codes with a diagnostic tool first, as some engine faults are caused by sensors or wiring rather than the control unit itself.
