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.

Condition: used, working, good.
Numbers to compare

- 5WP4000006 – 5WP… number (Siemens VDO / Continental numbering)
A 6K0906033 unit with any letter at the end is a different software or hardware version. If the number on your label ends with a letter, ask us before ordering.
Symptoms of a faulty ECU
- no start even though the ignition and fuel system are fine,
- rough idle,
- engine warning light and internal unit faults,
- loss of communication with the tester.
Before you replace the unit, check the earths and power supply and inspect the connector for moisture and corrosion.
How the ECU is prepared
You can choose the locked version, with the previous car's data and immobiliser – for workshops that will unlock, program and match it themselves – or the unlocked one, which we prepare before dispatch (most often in 1–2 working days).
PIN / CAR PASS, Virgin, IMMO OFF, auto programming or clone is not available for every ECU – it depends on the part number, software and immobiliser. Ask about the options for the 6K0906033 unit before you buy. Details: ECU preparation options.
