Label markings
- Bosch number: 0281013689 (0 281 013 689)
- Audi number: 4L0910401M (4L0 910 401 M)
- ECU type: Bosch EDC16CP34
Vehicle compatibility
The label decides, not the model year: the Bosch number 0281013689 and the Audi number 4L0910401M 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 – 0281013688 (4L0910401N) has different software and is not a replacement, and Q7s with EDC17 (e.g. 0281015868) use a different ECU type.
Preparation and installation
On the EDC16CP34, disabling the immobiliser has no side effects – there is no message on the instrument cluster and no stored fault, and the engine starts straight after installation. You can also choose data cloning from your old ECU (included in the price) and paid services: DPF OFF, EGR OFF, FLAPS OFF and 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
- the radiator fans run constantly with the ignition on
- corrosion on the pins or the circuit board
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).
