Vehicle compatibility
Before ordering, check two numbers on the label: 4L0910560G and 0261S02456. Your version missing from the description rules nothing out, but a different number, e.g. 4L0910560M (0261S02493), means a different version of the ECU. We list this unit for: Audi Q7 4.2 V8 FSI.
Installation and preparation
The immobiliser is switched off in the ECU itself, so once connected there is no programming and no errors. Want to keep the data from your own ECU? We will make a clone on request, from the ECU or files you send.
Symptoms of a failed ECU
A failed ECU can show different symptoms, for example:
- the engine does not start
- hard starting on a cold or warm engine
- rough engine running
- recurring ignition or injection errors
Before buying an ECU, rule out the power supply, earth and wiring – they can cause the same symptoms.
