Audi TT MK2 CDA 1.8T Alternator 06J 903 023 Q - Used Original Parts
Diagnosis and Common Symptoms
From a workshop perspective, a failing alternator on the VAG 1.8T/2.0T platform presents with clear, escalating symptoms. Initially, you may notice intermittent flickering of interior or exterior lights. As the unit degrades, the red battery warning light will illuminate on the instrument cluster, often accompanied by a "Generator Fault" message. In advanced stages of failure, the vehicle's ECU will begin shedding electrical load, causing systems like power steering to feel heavy or the radio to shut down.
Common diagnostic trouble codes (DTCs) logged in the gateway or engine control module include:
- 02252 - Generator
- 01117 - Generator Terminal DF Load Signal
- 00446 - Function Limitation due to Under-Voltage
A physical inspection may reveal a whining or grinding noise from the alternator bearings, especially upon start-up or under heavy electrical load.
