BMW 4 Series2020

• Strong market demand and sharp year-on-year price growth; expect quick sales and limited negotiation room at current valuations.
• Direct-injection petrol engines need regular fuel system cleaning (€200–400) to prevent carbon buildup causing rough idle and misfire issues.
• N55 turbo models: listen for timing chain rattle on cold starts—common wear after 80k km; tensioner replacement is costly if neglected.
• Inspect electric power steering responsiveness before purchase; loss of assist or excessive stiffness mid-drive signals electronic failure requiring dealer repair.
