How the engine fits this car

The entry-level trim on this 3 Series generation — the same N20 engine covered in detail on the 328i's page, simply tuned for less output.

A lower-cost way into this chassis generation, with the identical timing chain tensioner consideration to screen for.

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

Lower purchase price than the 328i on the same generation
Same chassis and interior as the 328i, just less power
Timing chain tensioner wear check, detailed on the engine page, is well documented
ZF 8HP automatic, where fitted, is one of the more dependable modern transmissions

Timing chain tensioner wear, covered on the engine page, applies identically to this lower-output tune
Noticeably less performance than the 328i
Oil consumption affects a meaningful minority of examples, per the engine page
Run-flat tyres, where fitted, are costly to replace

This 320i shares its N20 engine with the related 328i. Full detail on the timing chain tensioner consideration lives on the dedicated engine page.

Listen for a rattle on cold start that persists for more than a second or two.

Check oil level yourself if possible, since consumption can outpace the dashboard sensor.

If the car has the ZF 8HP automatic, ask about fluid service history.
