Engine Control System Type:
Likely Bosch Motronic ECU, specific version depends on engine.
Fuel Delivery System:
Multi-point Fuel Injection (MPI) or FSI (direct injection for some later variants, but MPI for 2000).
Ignition Type:
Electronic Ignition with Coil-on-Plug or Coil Packs.
NHTSA Crash Test Ratings:
While specific 2000 A6 ratings might vary, the C5 platform generally received good ratings for its era, often 4 or 5 stars for frontal impacts.
Anti Lock Braking System:
Standard ABS across all trims.
Traction Control:
Electronic Stability Program (ESP) / Traction Control (ASR) likely standard or optional.
Airbags:
Frontal airbags for driver and passenger, side airbags often standard or optional.
Oil Change Interval:
Typically every 5,000-7,500 miles or 6-12 months, depending on driving conditions and oil type used. Consult owner's manual for precise intervals.
Timing Belt Replacement:
For 2.8L V6 and 4.2L V8 engines, timing belt replacement is crucial, typically around 60,000-100,000 miles. 2.7T may have a timing chain or belt, check specific engine. This manual is for wiring, not engine mechanicals, but electrical components are critical for engine timing.
Engine Oil Type:
Recommended: Synthetic 5W-40 or 5W-30. Refer to owner's manual for specific VW 502 00 or 503 00 approvals.
Coolant Type:
G12 (pink/red) ethylene glycol-based coolant or equivalent.
Transmission Fluid Type:
Automatic: ATF SPIII or equivalent. Manual: Gear oil, GL-4 or GL-5 depending on specification. Consult manual for exact specs.
Electrical Gremlins:
Common electrical issues can include window regulators, central locking actuators, ignition coil failures, and ECU sensor failures. Accurate wiring diagrams are essential for diagnosing these.
Ignition Coil Failure:
A known weakness on some 2.7T engines, leading to misfires. Wiring diagnosis can help pinpoint issues if not the coil itself.
Door Lock Actuator Failure:
Common failure leading to central locking malfunctions, traceable via door wiring diagrams.
Mass Air Flow Sensor Issues:
Can lead to poor running conditions. Wiring to the MAF sensor is critical for diagnosis.
