Oil Consumption:
Some early TFSI engines (including the BWA) can exhibit increased oil consumption due to issues with piston rings or PCV systems. Regular checks and potentially PCV valve replacement are advised.
Dsg Transmission Problems:
While generally reliable, DSG transmissions can require periodic mechatronic unit servicing or clutch pack replacements. Maintaining correct DSG fluid levels and quality is crucial.
Haldex Coupler Maintenance:
For Quattro models, the Haldex all-wheel-drive system requires periodic fluid and filter changes for optimal performance and longevity.
Ignition Coils:
Faulty ignition coils can lead to misfires and rough running. Periodic inspection and replacement are part of routine maintenance.
Camshaft Follower:
Early TFSI engines had a known issue with the camshaft follower wearing prematurely, leading to potential camshaft damage. The manual would detail inspection and replacement procedures.
