2009 BMW 120 2.0L Diesel · NA59 HBZ

The latest MOT test on 2025-12-27 resulted in a pass, but the overall maintenance trend is currently worsening. While the vehicle has successfully passed its recent inspections, there is a recurring pattern of deterioration regarding the drivetrain and braking systems. The progression from a single deteriorated constant velocity boot to both rear inner boots being severely deteriorated, coupled with persistent advisories for worn and pitted brake discs, indicates that the vehicle is entering a phase of increased mechanical decline. The recorded mileage of 168,025 miles over approximately 17 years represents an average annual usage of 9,884 miles, which is typical for a vehicle of this vintage. This level of usage suggests that the car has not suffered from the pitfalls of long-term standing, such as seized calipers or perished seals, but it has accumulated significant wear on all major consumables. At this mileage, the buyer must anticipate that high-stress components, including suspension bushes, engine mounts, and drivetrain bearings, are likely reaching the end of their operational lifespan. Immediate priority must be given to the rear inner drive shaft constant velocity boots. Because these are recorded as severely deteriorated, there is a high risk that the joints have lost their lubrication and are contaminated with road grit. During a test drive, listen for rhythmic clicking or clunking noises from the rear of the vehicle, particularly during low-speed cornering. Additionally, the recurring advisories for pitted and scored front brake discs, alongside thinning rear pads, suggest that the braking system requires a comprehensive overhaul. The buyer should feel for any shuddering through the brake pedal under deceleration and visually inspect the discs for deep grooves or heavy corrosion. Beyond the specific MOT defects, the vehicle's age and mileage necessitate a rigorous physical inspection. Given the previous dangerous failure for a tyre bulge, a close examination of all tyre sidewalls for perishing, cracking, or impact damage is essential. The buyer should also verify the service history to ensure oil changes have been performed at appropriate intervals to prevent sludge build-up in the engine. Finally, check for oil leaks around the cylinder head and sump, and inspect the exhaust system for excessive corrosion or loose mountings, as these are common failure points for BMW models of this era with high mileage.
