About the 2013 BMW 523

The 2013 BMW 523 is a premium car. Our records list a 1995cc diesel engine, though engines vary between versions. 68 MOT tests were recorded on this model in 2024, making it a rare model on UK roads. It ranks in the top 2% of all 2013 models for MOT pass rate.

With an average of 48,039 miles recorded at its 2024 MOT tests, BMW 523 owners tend to use this car less than the typical driver.

2013 BMW 523 Fuel Costs

The 1995cc diesel engine offers a reasonable balance between performance and economy. Expect around 48 mpg in mixed driving, which works out to roughly £1,397 per year with diesel at 199.33p per litre (GOV.UK weekly average, week of 19 October 2026; based on 7,400 miles per year). Diesel cars of this age should have their DPF (diesel particulate filter) checked, as replacements can be costly.

Total estimated annual running cost is £1,927 (£161/month), broken down as £1,397 fuel, £275 road tax, £55 MOT, and £200 predicted repairs. The low repair estimate reflects the excellent 100% pass rate. These cars rarely fail their MOT, so unexpected bills are less likely.

BMW 523 Reliability Trend

Newer BMW 523s pass their MOT more often than older ones, by 6 percentage points on average, which is mostly down to age and wear.

Buying a Used 2013 BMW 523

At 13 years old, the BMW 523 is firmly in budget territory. Purchase prices are low, but check for rust, worn suspension bushes, and electrical gremlins. A full service history is especially valuable at this age. If you're flexible on year, the 2011 model has the highest pass rate at 84%. Note: with only 68 tests in our data, these figures should be treated as indicative rather than definitive.

Common Issues to Watch For

These are typical issues for cars of this age, fuel type and engine size, not faults recorded on this model's MOT tests. Use them as a checklist when you view one.

DPF (Diesel Particulate Filter)

Watch out

Short journeys clog the DPF. Replacement costs £1,000-£2,500. Check the DPF warning light and ask about driving patterns.

Turbo Wear

Watch out

Diesel turbos work harder and wear faster. Listen for whining noises and check for oil leaks around the turbo housing.

EGR Valve

Watch out

Exhaust Gas Recirculation valves clog with carbon deposits, causing rough running and poor economy. Cleaning costs £150-£300, replacement £300-£600.

Rust and Corrosion

Watch out

At 10+ years, check wheel arches, sills, subframe, and brake lines for rust. Structural corrosion is an MOT failure. Prevention is far cheaper than repair.

Suspension Bushings

Watch out

Rubber suspension bushes harden and crack with age, causing knocking noises and vague handling. A full refresh costs £300-£800 depending on the car.

Service History

Low risk

Always request a full service history. Regular servicing is the single best indicator of how well a car has been maintained, regardless of mileage.
