ABS warning light on a Seat Ibiza 09 plate

[Mickybunns]

Just wondering if I could get some people's opinions, recently took my car into garage for intermittent ABS warning light. They did their OBD Scanner and it pinpointed the issue to a Front off side sensor being the issue, but have they tried different brands of new sensors and still the issue has persisted. Bearing of the wheel has been checked and that's not the cause either. My first instinct which I told them when it first went in was going to wiring, but it seems they didn't bother to check that despite having the car for 2 days. Is there any other causes other than Wiring or Battery voltage for this issue?

If they changed the sensor after the diagnosis said sensor fault chances are it's wiring. Depends though on what the code said. Anyhow take it somewhere else where they know how to check electricity.
