Credov's researched list of the 7 faults the Volvo V40 is known for (2012–2016), 6 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Look along the top of the engine and the heat shield for dried coolant crust or wetness, and check the coolant level.
Why it matters: This is a known fire-risk pattern once the coolant-low warning is ignored, so it is worth checking even on a car with no warning light showing right now, since a cracked hose leaks slowly before it fails outright.
What to look for: In stop-start traffic and pulling away on a slope, feel for judder or slipping, and look underneath for fluid leaks.
Why it matters: Owner reports describe judder and failures recurring even after a repair, and the clutch or mechatronic unit replacement this gearbox needs once it fails is one of the larger bills on an otherwise cheap-to-run small Volvo.
What to look for: Check the coolant expansion tank is at MAX cold and look for dried coolant residue on the tank, hoses and turbo.
Why it matters: Because the leak is often slow and invisible underneath the car, a buyer can easily miss it, and letting the level run low risks a cracked head and fire rather than a simple hose repair.
What to look for: Ask for an invoice for the timing belt, tensioner and idler with the date and kilometres it was done.
Why it matters: Because this engine is often assumed to be chain-driven given how long the interval runs, a buyer can easily overlook that it still needs a belt change, and a belt that fails on this interference engine wrecks it.
What to look for: Ask for an invoice naming the timing belt, water pump (diesel) and auxiliary belt kit with the date and kilometres.
Why it matters: This is a scheduled interval rather than a fault, but on this engine family a seized auxiliary pulley left unchecked has wrecked engines at speed, so proof of both belts being done together is worth confirming.
What to look for: Scan for EGR or boost fault codes and watch for limp mode or hesitation on the test drive.
Why it matters: Beyond the drivability and fuel-use cost of a sooted EGR system, Volvo treated the overheating risk from a packed intake manifold on these engines seriously enough to act on worldwide, so this is worth checking even without an obvious fault showing.
What to look for: Look inside both headlamps for misting, droplets or water tide marks, especially after rain or a wash.
Why it matters: Repeated condensation left unaddressed can corrode the reflector and the lamp internals, turning a cheap ventilation fix into an expensive new headlamp unit.

On top of the faults above, every Credov inspection covers the basics: fuel smell, leaks or filler rust, engine oil leaks, power steering fluid leak, drive belt cracks or squeal, rust underneath: chassis and mounts, engine mounts, engine oil level and colour, coolant level, colour and leaks, head gasket failure signs, cold start: rattle, knock or smoke, rough or hunting idle, engine running hot on gauge, gearbox or diff oil leak, swapped gearbox without lvv and more.
