Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I work for Holden as a Technician.
Can you get a scan done on the whole vehicle please?
What engine does yours have?
Is it a 1.8 petrol or 1.9 Diesel turbo?
Z18XE or Z19DT?
That is correct.
It looks like a snowflake for driving in snow.
Of course, not many owners use that feature in Aussie land.
Don't feel bad at all, I've seen many times, with new owners.
All the best to you for happy motoring.
I hope my advice has been of assistance to you.
