The most recent MOT flagged tyre sidewall perishing on the nearside rear, offside front and offside rear, plus uneven outer-edge wear on the offside front tyre, so start by checking all four tyres for cracking, tread depth and wear pattern. Outer-edge wear can point to incorrect alignment, worn suspension bushes or dampers, so a quick check of the front suspension geometry and bushes is worthwhile on a car now eight years old. On the 1.5 diesel, look for any signs of DPF warning lights, excessive smoke on start-up, or turbo hesitation, and confirm the timing chain has been inspected as the engine approaches higher mileages. Finally, verify that all warning lights clear on ignition, the air-conditioning blows cold, and the infotainment and iDrive functions operate as expected, as electrical glitches are worth catching early.
