Label markings

- Audi number: 4L1910401 (4L1 910 401)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The label decides, not the model year: the Bosch number 0281014409 and the Audi number 4L1910401 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 – 0281014408 (4L0910401T) has different software and is not a replacement, and Q7s with EDC17 (e.g. 0281015868) use a different ECU type.
Preparation and installation
The 0281014409 unit is prepared as IMMO OFF – once connected, the engine starts without immobiliser programming or key coding, and no fault remains stored. Cloning the data from your old ECU is included in the price (send us the unit or the files). Paid options: DPF OFF, EGR OFF, FLAPS OFF, 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
- no communication with the ECU during diagnostics
- the radiator fans run constantly with the ignition on
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).
