# BMW 5 Series 2011–2017 · Pre-purchase checklist

Bring this to the inspection. Every check below is specific to this generation's documented failure modes, not generic used-car advice.

Check 01

On a 528i (N20): listen for a rattle or whine at cold start and 1,500–2,500 rpm, and ask for proof the timing chain/guides were replaced. A documented chain job is a major plus, not a red flag.

Check 02

On a 550i (N63): do an oil-level check, then ask how often oil is added between changes. BMW's own 'spec' allows up to a quart per ~750 miles, which is a lot. Ask for any CCP and valve-stem-seal records by VIN.

Check 03

Look under the car and around the oil filter housing and valve cover for oil weeping or burnt-oil smell. Leaks here are near-universal and can ruin the serpentine belt if ignored.

Check 04

Confirm the electric water pump and thermostat history; if it's the original on a high-mileage car, budget to replace it soon.

Check 05

Ask for ZF 8-speed transmission fluid + filter service history. 'Never done, it's lifetime fluid' means budget for a service immediately.

Check 06

Scan for stored codes with a BMW-capable tool (drivetrain malfunction, misfire, VANOS, fuel pump). Generic OBD readers miss most BMW faults.

Check 07

Check the HPFP and injectors on turbo cars: rough idle, hard cold starts, and hesitation point to known fuel-system wear.

Check 08

Test every electronic toy: iDrive screen, comfort-access door handles, parking sensors. Electrical gremlins are common and annoying.

Walk-away signals

2011 (first model year, earliest N55/N63 oil-leak and consumption complaints) · 2012–2014 N20 528i with no timing chain history · Any 550i (N63) without documented CCP work and a recent valve-stem-seal job
