BMW X1 Common Problems & Reliability

Based on 4,693 MOT tests from 537 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every BMW X1 has the same fault.

BMW X1's have a extremely good reliability rating of 774/999. The score was calculated from the average of every BMW X1 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Also check BHP & performance, road tax, fuel economy, and CO2 emissions for the BMW X1.

Common BMW X1 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore MOT data includes 897 advisory comments and 178 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: NEARSIDE FRONT TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake pad wear

VehicleScore MOT data includes 225 advisory comments and 13 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Ask for recent pad replacement and look at the remaining pad thickness.

Example MOT wording: REAR BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))

Brake disc wear

VehicleScore MOT data includes 104 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record brake discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: FRONT BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Suspension arm issues

VehicleScore MOT data includes 40 advisory comments and 29 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a worn, corroded, or damaged suspension arm or its pin.

What to inspect

Look for play or corrosion at the arm and ask whether it has been replaced.

Example MOT wording: NEARSIDE FRONT SUSPENSION ARM PIN OR BUSH WORN BUT NOT RESULTING IN EXCESSIVE MOVEMENT (5.3.4 (A) (I))

Oil leak

VehicleScore MOT data includes 46 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.

What to inspect

Look under the engine for fresh oil, and check the oil level.

Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))

Parking brake faults

VehicleScore MOT data includes 24 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a parking brake that did not hold well enough or had a component defect.

What to inspect

Test that the parking brake holds the car on a slope and releases cleanly.

Example MOT wording: PARKING BRAKE EFFICIENCY BELOW REQUIREMENTS (1.4.2 (A) (I))

Lamp and bulb faults

VehicleScore MOT data includes 14 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record a lamp or bulb other than a headlamp or indicator.

What to inspect

Switch on the side, brake, fog, and number-plate lamps.

Example MOT wording: OFFSIDE FRONT POSITION LAMP NOT WORKING (4.2.1 (A) (II))

Windscreen damage

VehicleScore MOT data includes 14 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record chips, cracks, or other windscreen damage in the driver’s view.

What to inspect

Look for chips and cracks, especially in the area swept by the wipers.

Example MOT wording: WINDSCREEN WASHER PROVIDES INSUFFICIENT WASHER LIQUID (3.5 (A))

What to check when buying a used BMW X1

This is an inspection checklist based on MOT comments in the VehicleScore sample. It does not mean the car you are looking at has these defects.

Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Suspension arm issues. Look for play or corrosion at the arm and ask whether it has been replaced.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Parking brake faults. Test that the parking brake holds the car on a slope and releases cleanly.
Lamp and bulb faults. Switch on the side, brake, fog, and number-plate lamps.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.

Buying a BMW X1?

Common problems tell you what can affect BMW X1s generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
