Label markings
- Bosch number: 0281012772 (0 281 012 772)
- Audi number: 4L0907401 (4L0 907 401)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The unit comes from an Audi Q7 4L 3.0 TDI. The model list does not limit the match either way – what matters is that the Bosch number 0281012772 and the Audi number 4L0907401 match the label on your ECU. The neighbouring number 0281012919 (4L0907401) is the same EDC16CP34 family but different software, so it cannot replace this unit. Q7 3.0 TDI models with EDC17 (e.g. 0281015868) use completely different ECUs.
Preparation and installation
Installation comes down to plugging in the connectors: the IMMO OFF version needs no key coding or immobiliser adaptation and leaves no faults. If you prefer a clone of your own ECU, we make it at no extra cost once you send the unit or its files. For an extra charge we can also prepare DPF OFF, EGR OFF, FLAPS OFF or chip tuning.
Symptoms of a failed ECU in the Q7
In the Q7 3.0 TDI the ECU sits under the scuttle panel; when the drains block, water collects there. The most common symptoms:
- the engine cranks but does not start
- the engine stalls when warm or after contact with moisture
- corrosion on the pins or the circuit board
Before buying, rule out the power supply, wiring and battery, as they cause similar symptoms. Read more here: water damage to the Audi Q7 3.0 TDI ECU (EDC16CP34).
