Nearly new buying guide: BMW 3 Series (F30)

Throughout, standard kit has always run to alloy wheels and climate control. SE models have dual-zone climate control, automatic lights and rear parking sensors and Sport cars get sports seats and other racy bits. The Modern trim reaches out to BMW newbies with more informal colours and Luxury ladles on the goodies. 

Can’t stretch to the mighty BMW  M3? You can always seek out the copycat M Sport, with its bodykit, larger alloy wheels and sports suspension. 

So where to find your used F30? You shouldn’t have to look too far. One major classified sales site is showing over 4000 at prices starting from £4399 for a 2012/12-reg 320d ED with 170,000 miles. At the other end of the spectrum, you can get into a 2018/68-reg 320d M Sport auto with 1500 miles for £32,985. Its all-new, G20-gen equivalent starts at £38k. 

At the time of writing, the cheapest BMW approved used F30 was a 2013 320d ED with 50,000 miles for £9424; not bad for a car with a 12-month warranty and full service history. All F30s have variable servicing. On cars under five years old, check if they were sold with the five-year servicing pack. It could save you some money. 

BUYER BEWARE 

Engine All variants have a timing chain and a ticking noise could be tensioner wear caused by infrequent oil changes. The N20 four-cylinder petrol engine in particular can experience timing chain problems. Warning noises include a whine or rattle. Fortunately, you can check the chain by unscrewing the oil filler cap and inspecting it but if it is noisy, the best advice would be to walk away. Diesel engines from 2015 onwards suffer fewer timing chain problems. Six-cylinder engines can suffer problems with their Vanos engine timing solenoids, leading to rough idling and a dip in power. A diesel that runs roughly may have a blocked EGR valve or a clogged DPF. Regarding all F30s, check the car turns over promptly on starting since starter motor problems are not uncommon. 

Transmission As the car is driven past you, listen for the rear diff making a noise. It's a common problem with all BMWs that have not had their diff fluid changed regularly, if at all. If the gearchange is obstructive, there are unpleasant vibrations when changing gears or you hear rattling noises, suspect the dual mass flywheel which has a history of premature failure. A less than smooth auto 'box may simply require fresh fluid and filters. 

Recalls The F30 3 Series has been the subject of a few recalls, some of them very serious, so be sure they've been actioned.

Brakes and suspension The model has a reputation for getting through pads and discs, so factor heavy wear into your offer.  

Body Check the rear lights for condensation and their seals for fit and tightness. Weak ones can let water into the boot. The paint has a reputation for shipping easily so inspect the bonnet and wings carefully.   

Interior The front seat frames can corrode, causing them to squeak. The Bluetooth system doesn't always pair successfully with a handset, so ask BMW for the update it offers. Check the odometer reading checks out with old MOTs and invoices. Listen for excessive wind noise from the windows at motorway speeds. A lifeless infotainment system may simply require a system reset. 

Need to know

Because it’s built so well, you should be alive to the risk of buying a clocked F30. In fact, it’s easy to give one a haircut because of its digital odometer but just as easy to interrogate the ECU and spot it. Check old MOTs, too. 

Options typically depreciate faster than the car they’re fitted to so look out for extra toys at no extra cost. One worthwhile option is folding rear seats, but walk away from oversized wheels, which do little for the ride. 

A full BMW service history may be expensive to maintain but it will always reward you with an easier resale. Still, don’t ignore the very capable BMW specialists out there who can save you money and who have more experience of older, leggier cars. 

Our pick

BMW 320d SE: Keep your sports suspension and big engines. We’ll take our F30 in SE guise with its more compliant suspension, powered by the 187bhp 320d diesel engine that can do up to 57mpg.

Wild card

BMW 340I M Sport Auto: The smaller engines and standard springs – that’s the route to the F30’s heart. The 340i M Sport has none of these so we’ll just take its 3.0-litre turbocharged six-cylinder petrol engine for all it’s got.
