hiya. what exactly is the spanner light for. is it an oil condition light as well as service due. ..?


would a air mas fault illuminate spanner or engine management light..

starting to think the spanners nothing to do with maf and i have two issues.

AFAIK spanner is purely "service interval" reached. (According to a preset value in the PCM).

All other faults should be properly diagnosed via Forscan or other quality brand diagnostics.

A fault code for a specific part does not necessarily mean that part is at fault.
But the system is determining that the values it is seeing for any particular sensor/actuator is not within it's recognised specification.

For example.
Fault with maf sensor.
Is it reading low or high.
Is it not showing a reading at all.

These could actually be faults with:
air filter,
Intake pipes,
Turbo,
Wiring: broken, shorted, or corrosion which can cause a difference in the signal being returned to the PCM due to either increasing or decreasing resistance in the circuit.
