VERDICT · BEST FOR HIGH-MILEAGE DRIVERS

Audi A4 2.0 TDI
is it a safe used buy?

The same B9 platform paired with the EA288 diesel — the stronger choice if most of your driving happens on the motorway rather than in town.

How the engine fits this car

The B9's light-for-its-class body means the 2.0 TDI doesn't have to work hard even in the lower 150 hp state of tune — this isn't a car that feels like it's straining to keep up with traffic.

As with the petrol version, Quattro trims add driveline complexity; for a car that's mostly doing predictable commuting miles, the simpler front-wheel-drive version is a reasonable way to cut long-term risk.

Audi A4-specific pros and cons

This is about the car itself — for engine-specific failure points, see the dedicated engine page below.

WHAT HOLDS UP WELL

  • Excellent motorway fuel economy, often comfortably under 5.5 L/100km on a run
  • EA288 is a more robust design than the diesel it replaced
  • Same strong interior and chassis as the petrol version
  • Quattro availability if you need the extra traction

WHAT TO WATCH

  • Not the engine to choose for a mostly-urban commute — EGR/DPF risk rises sharply
  • AdBlue system (where fitted) is another maintenance item to track
  • Diesel particulate filter replacement, if neglected long enough, is a significant repair cost
  • Resale demand for diesels has softened in some EU markets, affecting future value

The engine itself

This generation of A4 shares its 2.0 TDI with several other VW Group models of the same era. Full detail on EGR/DPF behaviour and typical failure mileage lives on the dedicated engine page.

Other engines in this generation

The B9 A4 was also offered with a petrol option — worth a look if your driving is mostly short or urban.

Pre-purchase checklist for this generation

Ask directly about driving pattern — this specific combination rewards motorway use and punishes short-trip-only ownership more than most.

Check service records for DPF regeneration or EGR-related work, and treat an unusually clean record on a high-mileage car with mild skepticism.

A live-data pre-purchase inspection will catch early DPF loading before it becomes a dashboard warning.
