2007 Volvo S40 1.8L Petrol · RF07 EXU

The Volvo S40 presents a mixed maintenance picture based on its most recent MOT record. The October 2025 pass at 123,618 miles came with multiple advisories that suggest the car has slipped from the clean bills of health seen in 2022, 2023, and early 2024. The tester flagged deteriorated suspension arm ball joint dust covers and anti-roll bar linkage dust covers on the offside front, both of which allow dirt and moisture to accelerate joint wear. A minor oil leak was also noted, along with both front tyres worn close to the legal limit and a damaged windscreen that did not affect the driver's view. These are not immediate failures, but they point to a vehicle that has not received thorough preventative attention in the last year. The trend is therefore worsening compared to the clean record of the previous three years. The mileage pattern tells a story of very light recent use. Between the December 2023 test at 115,749 miles and the October 2025 test at 123,618 miles, the car covered just 7,869 miles in nearly two full years. That is well below the already modest average of roughly 6,500 miles per year suggested by the 19-year total. Such low annual accumulation can be a double-edged sword. It limits wear on consumables like brake discs and tyres, but it also means the car may have spent extended periods standing, which can cause flat-spotted tyres, seized brakes, and dried-out rubber bushes. The clean passes between 2022 and late 2024 at around 113,000 to 116,000 miles show the car was used more consistently during that window, and the jump to 123,618 miles by October 2025 suggests a return to slightly more regular driving. A buyer should inspect the front suspension closely, particularly the offside lower arm ball joint and anti-roll bar linkage. Deteriorated dust covers mean the joints have been exposed to road grit and water, and any play or knocking over bumps would indicate the joints need replacement. The front tyres were already near the legal limit at the last test, so check whether they have been renewed since October 2025 or whether the car has continued to run on marginal rubber. The minor oil leak flagged at the last test deserves investigation. On a 2007 Volvo S40, common sources include the camshaft cover gasket, the oil filter housing seal, or the crankshaft oil seal. A visual inspection of the engine bay and underside should reveal whether the leak has progressed beyond the level the tester considered acceptable. The windscreen damage noted in the October 2025 test is advisory only, but any crack or chip in the driver's line of sight can worsen with temperature changes and road vibration. Confirm whether it has been repaired or replaced. The inoperative rear registration plate lamp is a simple fix but worth verifying. Given the low recent mileage, also check the condition of the brake discs and pads for surface corrosion from standing periods, and inspect the underside for any signs of structural corrosion, particularly around the subframes and suspension mounting points, which can be a concern on older Volvos that have not been undersealed.
