Maintenance
Service Intervals
Oil Change Interval:	Typically 5,000 to 10,000 miles (or 12 months) depending on driving conditions and oil used, often dictated by the vehicle's service indicator system (LongLife service may extend this).
Timing Belt Chain:	1.8T and 2.0T engines use a timing chain (generally maintenance-free for the life of the engine, but tensioners and guides can wear), while the 3.0L V6 uses a timing belt that requires replacement around 105,000 miles.

Coolant Type:	G12 or G12+ pink coolant (Ethylene Glycol based), mixed 50/50 with distilled water.
Transmission Fluid Type:	Manual: G 052 172 (or equivalent GL-4/GL-5); Automatic: G 055 025 (or equivalent ATF spec).
Power Steering Fluid:	Pentosin CHF 11S or equivalent hydraulic fluid.
Known Issues
Pcv System:	Clogged Positive Crankcase Ventilation (PCV) valve and hoses can lead to oil leaks, increased oil consumption, and rough idling, especially on 1.8T and 2.0T engines.
Ignition Coils:	Coil-on-plug ignition coils are prone to failure, causing misfires and rough running. Often requires replacement of all coils as a preventative measure.
Oil Leaks:	Leaking valve cover gaskets, oil pan gaskets, and oil filter housings are common due to age and material degradation.
HVAC Blower Motor:	Blower motor resistor failure can lead to the fan only working on the highest setting or not at all.
Timing Chain Tensioners:	Early 3.0L V6 engines (specifically pre-2005 B6) had issues with timing chain tensioners and guides, leading to rattling noises and potential catastrophic failure. The B7 and later 3.0 V6 revised this.
Oil Consumption Tfsi:	The early 2.0 TFSI (2.0T) engines could exhibit higher than normal oil consumption due to issues with piston rings and valve stem seals. Parts catalog is vital for replacement components.
