I lease a Seat Ibiza 1.4 16V Stella and have an interesting problem.
After 6 months the EPS light will show up occasionally. It's been back to the garage a few times for the issue where they reset the computer and fix the car. They test drove the car and found no problems. When I got the car back and drove 5 to 10km the EPS light came on again. This has repeated three times already.
The ECU gives the error: Brake pedal switch.
Both of the switches (break-> ECU, make -> brake lights) have been replaced already. They even replaced the wiring.
The interesting/frustrating part is that the mechanic drove the car for 50-100km in between repairs without the EPS light ever showing.
Is this a known issue? What can be done to fix it? Is it possible that this fault is influenced by driving styles?
I'm an electrical engineer by trade and have a basic understanding of car mechanics.
