Vehicle compatibility
This unit fits an Audi Q7 4L 3.0 TDI that left the factory with ECU 0281013688 / 4L0910401N. Before ordering, compare both numbers with the sticker on the housing – your model missing from the list rules nothing out, but a different number, e.g. 0281013320, means different software. EDC17 units from later Q7s (e.g. 0281015868) are a separate group.
Preparation and installation
The 0281013688 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:
- the engine cranks but does not start
- CAN bus faults and errors in several modules at once
- the radiator fans run constantly with the ignition on
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).
