Is the BMW 5 Series (F10) a reliable car?
A refined, spacious and economical car it may be, but the 5 Series isn't without its flaws and foibles. As with all German machines, if you look after it, it will look after you. So here are some of the things you should check before you buy:
Diesel engines: Those up to 2014 can suffer a sticky turbo wastegate and premature chain tensioner wear – listen for telltale rattling or tapping noises. Check that the 2011 recall concerning the exhaust gas recirculation (EGR) cooler has been actioned.
Petrol engines: The Vanos variable valve timing system can give trouble, flagged up by rattling at idle and poor performance. The high-pressure fuel pump and direct-injection modules are other weak spots.
Gearbox: On a car with an automatic gearbox, feel for jerky low-speed shifts and shuddering. Abused cars can suffer worn engine mounts that knock the manual gearbox out of gear. A high-mileage car may require a new clutch and dual-mass flywheel.
Steering and suspension: If the car is fitted with variable damper control, check the different settings are discernible on the test drive. Check the condition of the suspension springs and listen for unusual noises from the electric power steering system and for knocks and creaks from the suspension.
Tyres, wheels and brakes: Check for alloy corrosion, irregular tyre wear and that the brakes have plenty of life and aren’t binding.
Body: BMW 5 Series have a strong image and even older examples are worth repairing. For this reason, check the body for signs of painting and repair.
