Pre-facelift or facelift, this engine spans both
The same badge either side of the changeover. Bands are split at the facelift year from the generation record.
| Phase | Years | Low | Average | High | Good buy | What differs |
|---|---|---|---|---|---|---|
| pre Pre-facelift | 2004–2006 | €2,600 | €3,800 | €5,200 | €3,200 | The specification the car launched with. |
| LCI Facelift (LCI) | 2007 | €2,850 | €4,150 | €5,650 | €3,500 | Four-cylinder petrols switched from port-injection N45/N46 to direct-injection N43; Electric power steering replaced hydraulic on four-cylinder cars; Revised lights, bumpers and interior |
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 17 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.
1Static checksEngine off, ideally on a lift.
2On the driveInclude low-speed manoeuvring, not just an open road.
3PaperworkOn these cars the folder is most of the value.
4OBD 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.
High mileage is expected and fine; these engines routinely pass 300,000 km on maintenance.
| Service item | Interval | Cost |
|---|---|---|
| Engine oil Long life depends on regular oil | 15,000 km or annually | €90–140 |
| Swirl flaps Can drop into the engine if the linkage wears | roughly 150,000 km | €150–400 |
| Turbo actuator Variable vanes stick on short-run cars | as needed | €300–700 |

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 →

118d N47D20 2007–2011
Efficient, torquey, and carrying a rear-mounted timing chain that fails and takes the engine out with it. Then buy only with documented chain work.
Risk 4, High risk. The rear timing chain is the failure mode, and the engine-out repair costs a large share of the car.

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.
A silent cold start and documented chain history beat any mileage figure. So treat rattle as terminal.
| Service item | Interval | Cost |
|---|---|---|
| Engine oil Chain wear follows oil condition and level | 15,000 km or annually | €90–140 |
| Timing chain The failure that can end the engine | listen at every cold start | free |
| DPF regeneration Town driving blocks the filter | avoid short-trip-only use | €250–1,000 if blocked |

Good buy isn't the same as cheapest. Any car without documentation for rear timing chain failure should be priced as if the repair is still owed. Full breakdown by facelift phase →
