Diagnostics that find the fault, not a guess

Diagnostics at Molendinar

A check-engine light is a stored code, not a shopping list. We connect dealer-level scan tools, read manufacturer-specific codes (not just generic P-codes), look at live data and then quote the repair.

A flashing light usually means an active misfire — ease off and book in. A solid light can often wait overnight, but Queensland roadworthy inspections fail a car with the lamp on. If the code points at a sensor, we test the circuit before we sell you one.
