Label markings
- Bosch number: 0281014407 (0 281 014 407)
- Audi number: 4L0910401S (4L0 910 401 S)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The label decides, not the model year: the Bosch number 0281014407 and the Audi number 4L0910401S must be the same as on your ECU. If your Q7 version is not mentioned in the description, the unit may still fit. Watch out for similar numbers – 0281014406 (4L0910401R) has different software and is not a replacement, and Q7s with EDC17 (e.g. 0281015868) use a different ECU type.
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:
- no communication with the ECU during diagnostics
- CAN bus faults and errors in several modules at once
- the engine stalls when warm or after contact with moisture
These symptoms can also have another source (power supply, wiring, battery) – start with diagnostics. Details in the article: water damage to the Audi Q7 3.0 TDI ECU (EDC16CP34).
