06B903016AB 140 Amp Alternator for VW CC 2.0T TSI — Replace 06J903023C — OEM Generator

The Alternator (Generator) with OEM reference number 06B903016AB is a verified direct-fit replacement for the 2010 Volkswagen CC equipped with the 2.0T TSI engine (engine codes CCTA and CBFA). This 140-amp alternator is a critical component of the vehicle's charging system, responsible for converting mechanical energy from the engine into electrical energy to power all electrical systems and maintain battery charge while the engine is running.

The alternator powers essential systems including the ignition, fuel injection, lights, radio, power windows, and climate control, while simultaneously keeping the battery charged for starting. A failing alternator can lead to battery drain, dim or flickering lights, electrical system malfunctions, and ultimately, vehicle breakdown.

This OE-spec replacement alternator is manufactured to original equipment standards by leading suppliers including Valeo. It features a 140-amp output, 6-groove clutch pulley, and M8×1.25 output terminal, ensuring reliable performance and long service life under all operating conditions.

• Battery drains while the car is running
• Low voltage generated while driving
• Dim or flickering headlights or interior lights
• Electrical systems (radio, power windows) malfunction
• Battery warning light illuminated on dashboard

Before condemning the alternator:

• Perform a simple test with a DVOM (digital volt meter)
• Check that the drive belt is properly tensioned

(Reference VW workshop manual for complete steps):

1. Safety first — disconnect the battery negative terminal before starting work
2. Locate the alternator on the engine — typically on the front of the engine block
3. Remove the serpentine belt from the alternator pulley
4. Disconnect the electrical connector and output terminal
5. Remove the mounting bolts securing the alternator
6. Remove the old alternator from the vehicle
7. Compare the new alternator with the old unit — verify mounting points, pulley type (6-groove clutch), and connector position match
8. Install the new alternator into position
9. Torque mounting bolts to manufacturer specification
10. Reconnect the output terminal (M8×1.25) and electrical connector
11. Reinstall the serpentine belt — ensure correct routing
12. Reconnect the battery
13. Start engine and verify charging voltage (typically 13.5-14.5V at idle)

• When replacing the alternator, inspect the serpentine belt and tensioner for wear — replace if necessary
• Always use the correct belt routing diagram for your specific engine
• Consider replacing the battery if it is old or has been deeply discharged
