Label markings
- Bosch number: 0281013320 (0 281 013 320)
- Audi number: 4L0907401 (4L0 907 401)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The label decides, not the model year: the Bosch number 0281013320 and the Audi number 4L0907401 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 – 0281013298 (4L0910401F) has different software and is not a replacement, and Q7s with EDC17 (e.g. 0281015868) use a different ECU type.
Preparation and installation
The 0281013320 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
A typical cause of failure in the Q7 is water from the scuttle area where the ECU is mounted. Signs of damage include:
- 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
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).
