116i N43B16
The 1.6 direct-injection 116i from the 2007 facelift. Economical when healthy, and the same story as the larger N43: the piezo injectors and NOx sensors are what turn a cheap car into an expensive one.
Overview
The 116i is the N43B16 petrol version of the BMW 1 Series hatchback (E81), sold 2007–2011 with 122 PS and manual or automatic. Demands diligence at level 3. The piezo injectors and NOx sensors are the failure modes, and a set of injectors costs a large fraction of the car. 17 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.

Pre-purchase inspection
The same issue records, reordered into the sequence you can actually check them in: cold start, static, drive, paperwork.

Mileage and servicing
What the odometer does and doesn't tell you here, plus the service items whose neglect causes the expensive failures above.
Odometer matters less than a scan for injector and NOx codes. A well-documented high-miler beats an unknown low-miler.
| Service item | Interval | Cost |
|---|---|---|
| Engine oil Keeps the injection system clean | 12,000–15,000 km | €90–150 |
| Injector coding history Tells you which cars have already been done | on purchase | free |

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 →
