1998-2008 Volkswagen Pointer 1.8L I4 🇦🇺

Moderate SeverityPowertrain

Description

The ECU detected that the mixture adaptation (learned fuel trim) for Bank 1 has reached its maximum or minimum correction limit. The long-term adaptation values are outside normal operating range.

Symptoms

Check Engine Light
Poor fuel economy
Rough idle
Hesitation
Possible misfire

Common Causes

Vacuum leak
MAF sensor drift
Fuel injector fouling
Fuel pressure issue
Exhaust leak before O2 sensor

Diagnostic Steps

Reset adaptation values and monitor re-learning
Perform smoke test for vacuum leaks
Check MAF sensor readings
Test fuel pressure
Inspect for exhaust leaks before O2 sensor

Repair Notes

Repair the underlying air or fuel delivery issue causing adaptation limits to be reached.
