your brake fluid is low
No pad check on the Ibiza IIRC
even if it looks full fill it up abit more mine did it for ages and all i put in was a drop and it cured it. havent had a problem since
does the handbrake light flash and beep 3 times on start up and the abs light is on constant?
if so from experience (coming from 6n polos) you may have a faulty abs control module. get your fault memorys checked
