Antes de cambiar piezas

• Save fault codes and freeze-frame data before clearing anything.
• Check engine oil, coolant and transmission fluid using the correct temperature and service procedure.
• Verify power, ground, connectors, hoses, leaks and live data before replacing expensive parts.

Important notes

• Trim and engine availability depend on market; North America had fewer diesel options.
• Quattro AWD was optionally available across most trims and engines, affecting differential fluid requirements.
