Label markings
- Bosch number: 0281013691 (0 281 013 691)

- 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 0281013691 and the Audi number 4L0910401K match the label on your ECU. The neighbouring number 0281013690 (4L0910401L) 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
The 0281013691 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 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).
