BMW 430 Common Problems & Reliability

Based on 929 MOT tests from 111 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 430 has the same fault.

BMW 430's have a extremely good reliability rating of 778/999. The score was calculated from the average of every BMW 430 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.

Common BMW 430 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 168 advisory comments and 41 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 REAR TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake pad wear

VehicleScore MOT data includes 40 advisory comments and 6 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 check when buying a used BMW 430

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.

  • Steering rack issues. Check for play at the steering wheel and look for split rack gaiters.

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

  • Engine warning lamp. Switch on the ignition and confirm the lamp comes on and then goes out. Ask what was diagnosed if it stayed on.

  • Shock absorber issues. Look for oil misting on the damper body and listen for knocks over bumps.

Buying a BMW 430?

Common problems tell you what can affect BMW 430s 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.
