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.
N52 engine
xDrive28i (2011) · N52 bulletins
| Problem | When it shows up | What to know | Repair prices |
|---|---|---|---|
| Electric water pump and thermostat | about 60,000–100,000 miles | Overheating and limp mode. Replace the thermostat at the same time.1,2,3 | N52 / N54 / N55 electric water pump + thermostat |
| VANOS solenoids | about 70,000–130,000 miles | Rough cold idle, loss of power and codes 2A82/2A87.1,2 | VANOS solenoids (intake / exhaust) |
| Hydraulic lifter tick | usually 50,000 miles and up; 2008 and earlier | A tick on cold starts. It is annoying rather than harmful. BMW changed the lifters and head in December 2008, which fixed it.1 | No price yet |
| Valve cover and oil filter housing gasket leaks | about 60,000–100,000 miles | Oil smell and residue on top of the engine. A leaking oil filter housing can soak the belt.2,1 | No price yet |
N20 engine
xDrive28i / sDrive28i (2012–2017) · N20 bulletins
| Problem | When it shows up | What to know | Repair prices |
|---|---|---|---|
| Timing chain guides and oil pump drive chain | any mileage; BMW warranty extension is 7 years/70,000 miles | A whine from the front of the engine that rises with rpm, or a cold-start rattle. A broken guide can destroy the engine. BMW revised the chain parts from January 2015 production. Its warranty extension (SIB 11 03 17) covers listed 2012–2015 N20/N26 cars built up to mid-2015, for 7 years/70,000 miles from in-service. A class-action settlement (SIB 11 02 21) covers cars built through February 2015.4,5,6,7 | N20 timing chain replacement Owners paid: indie shop $2,375–$2,832 · dealer $3,550–$5,000 |
| Oil leaks and electric water pump | not tied to a mileage in our sources | Valve cover, oil filter housing gasket leaks and electric water pump failures also come up on higher-mileage N20s. | No price yet |
N55 engine
xDrive35i (2011–2017) · N55 bulletins
| Problem | When it shows up | What to know | Repair prices |
|---|---|---|---|
| Valve cover and gasket leak | about 60,000–100,000 miles | Burning-oil smell and oil on the spark plug wells. The plastic cover can also crack, so it is often replaced together with the gasket.8,9,10 | N55 valve cover / valve cover gasket (PCV) Owners paid: indie shop $930–$1,625 · dealer $1,450–$2,076 |
| Oil filter housing gasket leak | about 50,000–130,000 miles | Oil drips onto the belt and tensioner. Fix it before the belt is damaged.8,9,10,11 | N55 oil filter housing gasket (OFHG) Owners paid: indie shop $648–$763 |
| Electric water pump and thermostat | usually before 100,000 miles; reported failures range from about 30,000 to over 120,000 | Fails suddenly, often with no warning, then overheats.8,9,10 | N52 / N54 / N55 electric water pump + thermostat |
| Plastic charge pipe | can crack at any age, even at stock boost; about 40,000–90,000 miles (60,000–150,000 km) per EngineScope | Sudden loss of boost and a whoosh under load.8,10 | N55 charge pipe (intercooler to throttle) replacement |
| Oil pan gasket | usually past 100,000 miles | Expensive labor because the subframe must be lowered.8 | N55 oil pan gasket Owners paid: indie shop $1,588–$1,900 |
| VANOS solenoids | around 120,000 miles | Rough idle and cam timing faults.8 | VANOS solenoids (intake / exhaust) |
N47 engine
xDrive28d (2014–2017) · N47 bulletins
| Problem | When it shows up | What to know | Repair prices |
|---|---|---|---|
| Timing chain (rear-mounted) | cold-start rattle most often from about 80,000–130,000 miles | The chains sit at the back of the engine, so the gearbox has to come out to replace them. If ignored, the chain can snap and wreck the head. More common on the N47 than the N57, per Carsniffer (it also notes a 2015 tensioner recall in its market).12,13,14 | No price yet |
| Swirl flaps and EGR cooler | age | Broken swirl flaps can damage the engine; EGR coolers can leak.12,13 | No price yet |
Known F25 issues beyond the engine
N20 timing chains on early 28i models. Driving.ca says timing-chain problems, including outright failures, are more likely on 2011–2014 cars. BMW used revised chain parts from January 2015 and extended coverage on listed N20 cars.16,6,18
Exterior lighting. Some owners report LEDs working intermittently (often a bad solder joint on a circuit board, or a lighting module) and condensation inside the headlights.16

Matched from NHTSA's public recall file by model and model year. A recall may cover only some cars from a year, and it may already have been done on yours. Check by VIN →
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.19
- 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.20,21
- 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.20,22,23
- 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.24,20
- Run the onboard Check Status. With the engine warm, go to Vehicle > Check Status in iDrive for stored warnings. It doesn't replace a full scan or a pre-purchase inspection.16
- Walk around every light with a helper. Including the license plate lights, tailgate LEDs and headlights (look for moisture).16
- 28i: proof of timing-chain work. Ask for documents if the engine was repaired or replaced for chain problems.16
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.23,25
- 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.
- N52: ask for records of Electric water pump and thermostat; VANOS solenoids; Hydraulic lifter tick; Valve cover and oil filter housing gasket leaks.
- N20: ask for records of Timing chain guides and oil pump drive chain; Oil leaks and electric water pump.
- N55: ask for records of Valve cover and gasket leak; Oil filter housing gasket leak; Electric water pump and thermostat; Plastic charge pipe; Oil pan gasket; VANOS solenoids.
- N47: ask for records of Timing chain (rear-mounted); Swirl flaps and EGR cooler.
Which F25 to look for
Later 28i or the 35i. For the four-cylinder, later cars (revised chain parts from early 2015) carry less N20 risk. The 35i uses the N55 six (see the engine notes).16,6
These are the views of the cited reviewers and specialists, not a ranking of our own.
F25 specs
BMW's US figures we have on file run from 180 hp (X3 xDrive28d) to 300 hp (X3 xDrive35i), with 0-60 mph as quick as 5.3 s.
No manual gearbox appears in the EPA listings for this chassis. Full F25 specs: every US engine, transmission and drive by year →
Coding
The coding apps' own lists show 156 settings that owners can change on the F25 with a phone and an OBD adapter, in areas such as Seat heating/cooling, Convenient opening/closing, Display options iDrive system, Headlight cleaning, Tailgate, Mirrors. 134 come from BimmerCode's list and 22 more appear only in Carly's list.
Ownership costs
Routine maintenance: oil service prices by engine size, published BMW Value Service prices (brakes, spark plugs) from 16 US dealers, and the F25 maintenance schedule. Most F25 models: 4- and 6-cylinder $119.99 tier; diesel "Other".
