BMW E39 5 Series and M5 buyer's guide

Models and engines by year

US-market models. Chassis codes: E39. Not sure which one you have? The VIN check decodes year, model and engine.

Best and worst years

• Most owner complaints to NHTSA: 2003 (122 complaints, most about air bags) and 1997 (106 complaints, most about engine and engine cooling).
• Fewest, among model years at least four years old: 1998 (75 complaints, most about engine and engine cooling) and 1999 (91 complaints, most about service brakes).

Complaints are owner reports filed with NHTSA for that model year, matched to the E39 by model name, year and VIN pattern. A dash means too many of that year's complaints (more than a quarter) could belong to another generation sold the same year, so we leave it blank. These are raw counts, not rates: they aren't adjusted for how many cars were sold, and older cars have had more time to collect reports. The number after each engine counts BMW warranty extensions, class-action settlements and emissions recalls whose title names that engine, leaving out extensions on emissions-control parts; see the engine reliability ranking.

Known problems and when they show up

Mileages are what the cited shops, specialists and owner forums report. They are typical ranges, not predictions for any one car.

Test drive and inspection checklist

1. 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.⁴
2. 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.^5,6
3. 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.^5,7,8
4. 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.
5. 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.^9,5

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.^8,10
• 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.
• M54: ask for records of Cooling system (water pump, thermostat, expansion tank, hoses, radiator); CCV (crankcase ventilation); Valve cover gasket, oil filter housing gasket and DISA valve; Oil pump nut.

Ownership costs

Routine maintenance: oil service prices by engine size, published BMW Value Service prices (brakes, spark plugs) from 16 US dealers, and the E39 maintenance schedule.

By model year

Recalls and warranty extensions are counted when their published model-year range includes that year. Each one may cover only some cars, so check by VIN. Repairs counted are the ones whose engine was offered that year.
