If you see an ESP fault code on your Audi Q7, you'll need a special diagnostic tool from the dealer to check the vehicle's codes. ESP, which stands for electronic stability program, helps maintain traction in your SUV. Normally, the ESP light should flash when traction is lost, but if it's constantly on, there could be a system issue. If you can't access the diagnostic tool, you can check the ESP sensors at each wheel for signs of looseness or damage, as this might be causing the problem.
If there are ESP faults causing the engine not to start, it could be due to a power supply issue to the ECU or a problem with the ABS/traction control system shutting down the engine early.
