2022 BMW M135I Xdrive Auto 2.0L Petrol · WR22 YSE

The most recent MOT, carried out on 11 June 2026, was passed but included an advisory that the rear brake pads are wearing thin. The preceding test on 22 May 2025 also passed with no recorded defects, indicating a generally stable maintenance record over the past year. The emergence of brake‑pad wear is typical for a vehicle of this age and mileage and does not suggest a deteriorating trend, but it does flag a near‑term maintenance item that should be addressed before the next service. At four years old the M135i has logged only 23 381 miles, averaging roughly 5 800 miles per annum. This is considerably below the industry norm for a performance hatchback and points to either light, predominantly short‑haul use or periods of extended storage. Low annual mileage reduces cumulative wear on engine, transmission, and suspension components, yet prolonged standing can accelerate ageing of rubber seals, bushings and tyre sidewalls, and may encourage corrosion on brake discs and exhaust mounts if the car has been stored in a damp environment. Prospective buyers should give the rear braking system close attention. Visually inspect the rear pads for remaining thickness; a typical service interval for replacement on this model is around 30 000 miles, but thin pads can cause uneven disc wear or reduced stopping performance. During a test drive listen for any squeal, grinding or pulsation when applying the rear brakes, and feel for any pull to one side that could indicate uneven pad wear or a sticking caliper. It is also prudent to examine the front pads and discs, as they often wear at a similar rate on a rear‑biased, xDrive chassis, and to check that the brake fluid is clear and at the correct level, since fluid can absorb moisture over time. Given the low mileage and potential for long periods of inactivity, the buyer should inspect the tyre tread depth and sidewall condition, looking for cracking, dry rot or bulges that are more a function of age than wear. Verify the 12‑volt battery’s state of charge and consider a load test, as batteries can deteriorate after a few years even with limited use. Examine all suspension bushings, ball joints and coil‑spring mounts for any signs of hardening or cracking, and ensure that fluid reservoirs for engine oil, gearbox, coolant and power‑steering contain fresh, correctly coloured fluids without particulates. A thorough visual check of the under‑body for rust, especially around the rear subframe, exhaust hangers and wheel arches, will help confirm that the car has not suffered hidden corrosion during any storage intervals. Addressing these time‑based items now will help maintain the M135i’s performance and reliability.
