6.0/10
2 walk-away risks, 5 serious faults, 1 minor fault documented for this generation, weighted by severity and repair cost. Biggest factor: n47 diesel rear timing-chain wear. Score methodology.
The E90-generation 3 Series is still one of the best-driving used BMWs, but the buying decision is engine-led. The safest money is a late N52 325i/328i/330i with oil-leak paperwork, or a well-kept diesel with recall status clean. The traps are N54 turbo fuel-system and injector faults, N47 timing-chain risk in European diesels, M57/335d emissions hardware, electric water pump failure, oil-filter-housing leaks that can damage belts, xDrive transfer-case stress, and unresolved Takata/VANOS-bolt recalls.

Best years
2009-2011
Best buys
- 2009-2011 N52 petrol with cooling-system and oil-leak invoices.
- Manual or ZF automatic six-cylinder petrol with clean scan and no warning lights.
- Diesel only if mileage pattern, DPF/EGR history and recall status make sense.
Inspect hard
- N54 335i for HPFP, injector index, turbo wastegate, oil leaks and tune evidence.
- N47 316d/318d/320d for rear-chain noise and oil interval history.
- xDrive cars for four matching tyres and transfer-case behaviour.
Avoid
- Any car with active airbag recall, timing/VANOS bolt recall warning, overheating history, or belt ingestion evidence.
- N54 with misfire, fuel smell, boost rattle or unknown injector/HPFP history.
- Diesel with DPF/EGR delete, short-trip soot issues or unresolved emissions faults.
Next checks
Before you contact the seller
Check the car's history first. Then bring the right tools if it still looks worth viewing.
Primary next step
Check history, title, and recall status
The faults above matter more if the car also has accident history, finance flags, missing service records, or open safety recalls.

Engines and trims
Which BMW 3 Series should you buy?
On most used cars, the engine and trim choice changes the risk more than the mileage does. Narrow this down before you start viewing cars.
N46/N43 four-cylinder petrol
2005-2013 Europe
INSPECT CAREFULLY
Lower running costs, but timing, NOx, coil and oil-leak issues can erase the saving.
N52 six-cylinder petrol
2005-2011
BEST MAINSTREAM BUY
Usually the most durable E90 petrol if oil leaks, electric water pump and VANOS-bolt recall status are handled.
N53 direct-injection six-cylinder petrol
2007-2013 Europe
GOOD ONLY WITH CLEAN FUEL SYSTEM
Drives well, but injectors, NOx sensor and HPFP-type symptoms need scan evidence.
N54 / N55 335i
N54 2006-2010, N55 2010-2013
SPECIALIST BUY
Fast and desirable, but turbos, injectors, HPFP, cooling and tuning history decide ownership cost.
M47 / N47 / M57 diesels
2005-2013 market dependent
BUY THE RIGHT HISTORY
Strong motorway engines, poor blind buys when chains, swirl flaps, DPF, EGR or turbo history is vague.
Year notes
Year-by-year buyer advice
Use this to narrow the search before you spend time travelling to view a car.
2005
E90 sedan launch with early N52/N46 engines.
Buyer: Buy only on condition; age now matters more than mileage.
Owner: Cooling refresh and leak control protect resale.
2006
E91 Touring and E92 Coupe arrive; 335i/N54 begins in many markets.
Buyer: N54 needs specialist inspection, not a normal test drive.
Owner: Keep fuel-system and turbo paperwork.
2007
N53/N43 direct injection appears in Europe; E93 convertible expands range.
Buyer: Scan for NOx/injector/fuel-pressure faults.
Owner: Misfires need diagnosis before catalyst damage.
2008
LCI sedan/touring phase begins; diesel range shifts toward N47.
Buyer: Prefer LCI condition, but listen carefully for diesel chain noise.
Owner: Short oil intervals matter on N47.
2009
Mature LCI supply and strong N52/N54/N47 mix.
Buyer: Good year if recalls and leaks are clean.
Owner: Keep VIN recall printouts.
2010
N55 starts replacing N54 in 335i by market.
Buyer: N55 reduces some N54 fuel-system risk but still needs cooling and leak checks.
Owner: Service the automatic gearbox despite lifetime-fill claims.
2011
Final sedan/touring period before F30 arrives.
Buyer: Late N52 cars are the sweet spot.
Owner: Fix oil leaks before sale.
2012
E92/E93 coupe/convertible continue while F30 sedan launches.
Buyer: Verify body style; a 2012 E90-family car is usually coupe/convertible.
Owner: Convertible roof drains and seals need yearly attention.
2013
Final E92/E93 production.
Buyer: Pay late-car money only with exceptional paperwork.
Owner: Preserve service records; late coupes are enthusiast-owned now.
Common problems
Faults to check before buying
What fails, what it looks like, what it costs, and the quick checks you can do at the viewing - ranked by how badly each one can hurt you.
Fault 1
N54 HPFP, injector and turbo wastegate stack
Affects
2006-2010 335i/335xi, strongest on tuned or poorly documented cars.
Symptoms
Long crank, misfire, limp mode, fuel smell, rough cold start, wastegate rattle, underboost.
Typical repair cost
EUR 600-1,500 HPFP; EUR 1,200-3,000 injectors; EUR 2,000-5,500 turbos.
Codes / scan clues
29DC, 2AAF, 30FF, misfire and fuel-pressure BMW codes.
Root cause: High fuel pressure instability, piezo injector leakage/index mismatch and turbo wastegate wear.
Quick check
- Cold start and listen for rough idle or injector tick beyond normal.
- Scan DME for shadow fuel-pressure, misfire and boost faults.
- Check injector index numbers and HPFP invoices.
- Road test full boost after warm-up and listen for wastegate rattle.
Fault 2
N47 diesel rear timing-chain wear
Affects
2007-2013 European 316d/318d/320d, especially early N47D20A and long oil intervals.
