Hi, I have a 2013 panda trekking diesel with 110k km on it. Never had a single problem driving it up and down the east coast of Oz. it hasn't even needed brake discs or pads. oil warning symbol came on today with occasional message to change the oil. Its not due a change yet. oil level good. Any ideas? Do these cars have a sensor for oil quality as I used a different service last time. Thanks for any ideas.
