Test drive and inspection checklist
- Run the VIN for open recalls. Open safety recalls are free at any BMW dealer. Check on NHTSA's site or our recall page before you buy.7
- Scan for stored fault codes with a BMW-capable tool. A generic OBD reader misses most BMW modules. Specialist guides recommend a BMW-level scan (ISTA or similar) to catch faults that have been cleared from the dash but still stored.8,9
- Start it from cold. Ask the seller not to warm the car up first. Chain rattle, VANOS rattle, lifter tick and rough idle show most clearly in the first seconds after a cold start.8,10,11
- Ask a BMW dealer about warranty extensions and campaigns. Several BMW warranty extensions follow the car, not the owner, and some reimburse earlier repairs. A dealer can check the VIN. The list for this chassis is below.
- Get a pre-purchase inspection from a BMW specialist. A few hundred dollars for an independent BMW specialist is the usual advice, especially for M cars and high-mileage turbo engines.12,8
Engine items to listen and look for are in the known problems section.
Service-history red flags
- Oil changes only at the long computer interval. Several guides advise changing oil more often than the onboard service indicator (CBS) suggests, especially with lots of city driving.11,13
- Gaps in the records around known failure mileages. If the engine section below lists a job that usually comes due at the car's mileage, ask for the invoice. A missing record isn't proof it wasn't done, but it is a negotiating point.
- Tuned or "deleted" cars. Tunes, emissions deletes and removed parts complicate warranty claims and inspections and raise wear on turbo cars. Ask, and look for aftermarket intakes, downpipes and charge pipes.
- B46/B48: ask for records of Coolant leak at the oil filter housing; Brittle coolant hoses and couplings; Turbo oil return line leak (early cars); Fuel tank vent (purge) valve.
