2009 BMW Z4 2.5L Petrol · EY59 VJG

A critical deficiency in the electronic parking brake system dominates the recent MOT record, with a 2026 failure reporting both dangerous parking‑brake efficiency below 50 % and a major fault rendering the electronic parking‑brake control inoperative. The same test added advisories for a perished fuel‑cap seal and multiple tyres approaching the legal tread limit, while the preceding year flagged tyre cracking but recorded no functional failures. Earlier tests from 2020 to 2024 were clean, indicating that the current safety concern is a new development rather than a long‑standing issue. The odometer reads 71,618 mi after 17 years, averaging just over 4,200 mi per annum – a mileage level that is low for a sports‑car of this age. Such limited use reduces cumulative wear on engine and drivetrain components, yet the tyre wear and cracking observed are more typical of age‑related degradation than of mileage. The uninterrupted annual MOT schedule shows no testing gaps, suggesting the vehicle has been driven regularly enough to be presented for inspection each year, but the low annual accumulation also raises the possibility of extended periods of inactivity that can accelerate rubber hardening and brake‑system seal ageing. The parking‑brake fault must be rectified before the car can be considered road‑worthy; a thorough inspection of the electronic actuator, associated wiring, and the mechanical linkage is required, followed by functional testing on an incline to confirm that the handbrake holds the vehicle securely. All four tyres should be replaced promptly, as the combined advisories cite tread close to the legal minimum, edge wear, inner wear and visible cracking – conditions that compromise grip and can lead to sudden loss of traction. The perished fuel‑cap seal should be swapped for a new OEM cap to restore proper evaporative‑emission sealing and avoid future MOT failures. While the MOT history does not highlight suspension or brake‑line defects, the vehicle’s age warrants a visual inspection of suspension bushes, ball joints and coil springs for any signs of corrosion, cracking or excessive play, and a check of the front and rear brake discs and pads for uneven wear or glazing. During a test drive, listen for any knocks over bumps, feel for steering pull or vibration, and verify that the service brake pedal feels firm with consistent travel. Confirm that the parking brake, once repaired, engages smoothly and holds the car on a gradient without slippage. Addressing these points will bring the car back to a condition that satisfies the statutory safety standards.
