535i N54
BMW's first modern turbo six. Strong bottom end, huge tuning headroom, and a fuel and boost system that bills you in €800 increments forever.
Overview
The 535i is the N54 petrol version of the BMW 5 Series wagon (E61), sold 2007–2010 with 306 PS and manual or automatic. High risk at level 4. The twin-turbo fuel system, the turbos and the cooling all fail in turn, and each repair runs into four figures on a car that's now cheap. 23 failure modes are recorded against its engine, gearbox, chassis and shared components. Prices on this page are illustrative placeholders rather than a sourced market sample. See the methodology for how the bands are derived.

Known issues, ranked by expected cost
Faults recorded against this engine, its components and its chassis, ranked by likelihood × repair cost. Costs are indicative ranges with a stated labour basis.
Ranked by probability × repair cost, not by how loudly a failure is discussed. Inherited from the engine, gearbox, chassis and shared components, each written once. All 23 issues in full →
Pre-purchase inspection
The same issue records, reordered into the sequence you can actually check them in: cold start, static, drive, paperwork.
1Cold startYou get one. If the engine is warm when you arrive, come back another day.
2Static checksEngine off, ideally on a lift.
3On the driveInclude low-speed manoeuvring, not just an open road.
4PaperworkOn these cars the folder is most of the value.
5OBD scanMandatory. A seller who refuses a scan has answered the question.
Mileage and servicing
What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.
Receipts matter more than mileage. Assume anything undocumented is due, because on this engine it usually is.
| Service item | Interval | Cost |
|---|---|---|
| High-pressure fuel pump A known N54 item and a four-figure one | as it fails | €800–1,200 |
| Walnut-blast intake Direct injection carbons the valves | roughly 100,000 km | €350–550 |
| Cooling system Plastic tank, pump and thermostat are wear items | roughly 120,000 km | €700–1,300 |

United States vs Europe
1 EUR = 1.08 USD ·US figures are the EU band converted at a stated rate. No US market differential is modelled: we hold no sourced US asking prices, and inventing one would be worse than saying so. What the comparison does show for real is availability. Most of this range was never sold in the US.

Good buy isn't the same as cheapest. The good-buy figure assumes the known failure items are either done with receipts or verifiably not yet due. Full breakdown by facelift phase →
