Is the BMW X1 reliable?

The BMW X1 has 2 known faults in our database across 2 generations, 2 of them rated high severity. The most serious are engine (the petrol X1 20i and 28i built from late 2011 until the E84 ended in 2015 use the N20) and engine (the N47 timing chain sits at the REAR of the engine, next to the flywheel and gearbox). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.

That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.

Which BMW X1 years should you avoid?

No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.

BMW X1 E84 (2009 to 2015) problems

Engine/EmissionsHigh severity🔧 Specialist mechanic

The N47 timing chain sits at the REAR of the engine, next to the flywheel and gearbox, so getting to it means removing the gearbox or dropping the engine. The original chain and plastic guides were underspecified: guides break up, the chain stretches and can snap, bending valves and in bad cases destroying the engine. Debris from the guides can also block the oil pump pickup and wipe the bearings. BMW issued revised parts (redesigned guides and crankshaft) under a quality-enhancement programme and later builds fail less often, but revised N47T engines still fail, so a late build date is not a clean bill of health. Specialist chain jobs start around 1350-2500 pounds; after a snap, a rebuild runs 3000-6500 pounds. The N47 arrived in 2007 and gave way to the B47 across 2014 and 2015 (the 5 Series first, then the 1 Series and 3 Series; the X1 kept the N47 until the new model arrived in 2015), so a car from either changeover year needs its engine code confirming before this applies

Rough guide
£1350-6500

Typical symptoms

  • rhythmic scraping or metallic rattling from the REAR of the engine, near the bulkhead
  • engine management light or camshaft correlation fault codes
  • sudden loss of power or complete engine failure with no prior warning

Affected vehicles

Engines:
2.0d (N47 / N47T): 116d, 118d, 120d, 318d, 320d, 520d, X1

Engine/EmissionsHigh severity📝 Editorial

The petrol X1 20i and 28i built from late 2011 until the E84 ended in 2015 use the N20 2.0 turbo engine. Its early timing chain guides were made from a plastic that degrades, letting the chain slacken and jump a tooth on the camshaft sprocket; because the N20 is an interference engine, pistons and valves can then collide. Fragments of guide collect in the sump and can block the oil pickup. A second, smaller chain drives the oil pump and can fail independently, so both are normally renewed in one job. Diesel versions of this X1 use a different engine, and the X1 launched in 2015 does not use the N20

Typical symptoms

  • brief rattle or tinkling from the front of the engine after a cold start
  • drivetrain malfunction warning or engine management light
  • camshaft correlation fault codes stored
  • misfire or rough running once the chain has jumped

DVSA R/2012/081701 vehicles affected in the UK

Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.

BMW X1 timing chain, and service intervals

A timing chain has no change interval, which is not the same as lasting for ever. Listen for it on a used X1, and check the oil has been changed on time. These are the figures UK specialists work to.

Timing chainChain
N47, 2.0D, 2.0 DIESEL
No fixed replacement interval

Rear-mounted timing chain stretches over time leading to catastrophic snapping. No fixed interval, but listen for a rhythmic scraping noise from the back of the engine on cold start. BMW's 2009 design modifications reduced the likelihood of failure but did not eliminate it.

Automatic gearbox oil
8-SPEED, 6-SPEED
60,000 miles or 8 years, whichever comes first

BMW claims the ZF gearbox is 'sealed for life', but ZF themselves (the manufacturer) prescribe fluid and filter changes. Published figures range from ZF's 100,000 km / 8 years guidance to specialist advice of 70,000-80,000 miles; 60,000 miles is recorded as the conservative end of that range.

Transfer case (ATC) oil
50,000 miles

BMW treats the xDrive ATC transfer case as sealed-for-life, but specialists recommend changing the DTF-1 (75W GL-4) fluid every 50,000-60,000 miles; 50,000 recorded here as the shorter end of the published range. Neglected fluid accelerates wear of the multi-plate clutch pack that apportions drive between axles, a four-figure repair. Ask for evidence of transfer case servicing on any higher-mileage xDrive car.

Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.

BMW X1 buying questions

Which BMW X1 years should I avoid?

No BMW X1 year is a write-off, but the E84 (2009 to 2015) carries the most serious faults: engine. The F48 (2015 to 2022) has none rated high severity. Year matters less than whether the specific car has had the known fixes, so check the history for them.

What should I check when viewing a used BMW X1?

Ask the seller about the engine faults on this page and whether they have been fixed, with invoices. On the test drive watch for brief rattle or tinkling from the front of the engine after a cold start and rhythmic scraping or metallic rattling from the REAR of the engine, near the bulkhead. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a BMW X1 advert →

Are there any recalls on the BMW X1?

The DVSA lists 40 safety recalls for the BMW X1 issued between 2012 and 2026. The most recent, from January 2026, is "Replace the Driver's Airbag - Takata PSDI-5". Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it. This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.

What is the real MPG of a BMW X1?

Owners report 42.4 mpg on average across the BMW X1 engines with data, about 83% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 1,124 owner submissions. BMW X1 Real MPG by engine →

Where this BMW X1 fault data comes from

If you used to check the Honest John “Good & Bad” section before the site closed in 2026, this page is where that information now lives. We rebuilt the BMW X1 owner-report history from the archived Honest John dataset, added our own research, specialist and owner-club sources and DVSA recall data, and we keep it free. Each fault above is badged with its source. The same data feeds our free advert check, which reads a listing against every known fault for the exact engine and year.

Before you go and see it

Knowing what a BMW X1 goes wrong with is half of it. The rest is reading the advert and checking the car's history before you hand any money over.
