Check a Volkswagen Passat advert (free) →The B8 Passat (2014 to 2023) with the 2.0 TDI is the safer buy, since none of the serious known faults that reach this generation names that engine. What's there sits in versions you can check for or sidestep: the 7-speed DQ200 DSG on 1.4 TSI and 1.6 TDI cars, leaking sunroofs on 2016 cars and a switch fault that stops 2016 and 2017 1.4 TSI hybrids from starting.
A B7 (2010 to 2015) is a bigger gamble, above all as a manual, because its most reported known fault is the clutch and dual mass flywheel failing at 25,000 to 50,000 miles, sometimes damaging the gearbox casing. The EA189 2.0 TDI's EGR valve and DPF can pack up after the emissions software fix, and a DSG with the 1.4 TSI or 1.6 TDI brings in the DQ200 fault. If you're set on a B7, check a 2.0 TDI DSG's cambelt, EGR and auxiliary belt history.
Go carefully with a B6 (2005 to 2010). Its electric handbrake has more owner reports against it than any other Passat fault, and the 2.0 TDI PD diesels of these years carry serious known faults for oil pump drives failing at 80,000 to 120,000 miles, porous cylinder heads and injectors that cut the engine out. Snapping rear coil springs and failing power steering racks are known faults across all 2005 to 2011 cars as well.
A B5 (1997 to 2005) isn't worth buying unless the carpets are dry and the drains are clear, because water getting past blocked plenum chamber drains is a known fault across all its years, damaging the ECU and, on 2001 to 2005 cars, rotting the brake servo until the pedal goes hard. Cars from 1997 to 2000 add front wishbones and rear brake seals failing at around four years old, and 2001 to 2005 cars rust through their front wings.
The B8's 2.0 TDI is the diesel to go for, because every serious known fault naming the 2.0 TDI covers cars up to 2011, though you'll still need to check the rear brake discs and, on a 2014 or 2015 manual, the clutch. The B6's pump injector (PD) 2.0 TDI is the one to avoid: on 2005 to 2008 cars the oil pump drive fails at 80,000 to 120,000 miles and ruins the engine, and 2007 to 2011 PD engines have porous cylinder heads that leak coolant.
The PD 170 from 2006 to 2009 also has Siemens piezo injectors that short out and stop the engine dead while it's being driven. On 2009 to 2011 2.0 TDIs, diesel weeping from a leaky fuel filter can soak the auxiliary belt until it shreds and fouls the timing belt, ruining engines at 70,000 to 100,000 miles. The B7's EA189 2.0 TDI suffers EGR valve and DPF failures after the emissions software fix, and specialists change its cambelt, water pump and tensioners every 60,000 miles or five years.
The 7-speed DQ200 dry clutch DSG is the gearbox to avoid. It's paired with the 1.2 TSI, 1.4 TSI and 1.6 TDI from 2008 to 2018, and its mechatronic unit fails and clutch packs wear out at 40,000 to 80,000 miles. B7 2.0 TDI DSGs have a six-speed wet clutch gearbox that the DQ200 fault doesn't cover. Manuals from 2011 to 2015 carry their own serious fault, with the clutch, flywheel and slave cylinder failing from 25,000 miles.
Among the petrols, the B7's 1.4 TSI has a timing chain rather than a cambelt, and the chain can stretch and its tensioner fail, showing up as a metallic rattle from cold. The B8's 1.4 TSI uses a long-life cambelt due at five years or about 120,000 miles. The 2015 1.8 and 2.0 TFSI have a known fault where the rear camshaft lobe shears off, cutting power and brake assistance, and the 2016 and 2017 1.4 TSI hybrid's switch for the high-voltage battery can fail and stop it starting.
Press a hand into the front footwell carpets on any Passat, and don't buy one that's damp. Blocked plenum chamber drains, the one under the battery above all, let in water that can ruin the ECU, and on a 2001 to 2005 B5 it can rot the brake servo, so a rock-hard brake pedal is a bad sign. On a 2016 car with a sunroof, look for drips from the headlining and pillars and try every button on the steering wheel.
Apply and release the electric handbrake several times on a 2005 to 2011 car, on a slope if you can, listening for grinding or buzzing from the back wheels and watching for its warning light. On 2015 and 2016 cars, pull away with Autohold switched on and make sure it lets go every time. See that the rear of a 2005 to 2011 car isn't sitting low, since snapped coil springs are a known fault, and that the steering isn't heavy at low speed.
On a 2011 to 2015 manual, pull away gently several times: judder or a rattle from the gearbox at idle points to the clutch and flywheel, and a spongy clutch pedal that sticks down points to the slave cylinder. With a DQ200 DSG, judder in first or second and flashing PRNDS lights are the signs. Run the air conditioning, because compressors have failed repeatedly on 2005 to 2011 and 2013 to 2015 cars, and look at the rear discs of 2016 and 2017 cars for heavy corrosion.
Ask for the receipt for the cambelt, water pump and tensioners on a B7 2.0 TDI, due every 60,000 miles or five years, plus paperwork for its emissions software fix and any EGR valve work since. A 2011 diesel with stop/start needs proof of the recall that replaced the starter solenoid switch, since a stuck starter can overheat and catch fire. On a B6 2.0 TDI PD, a full VW dealer service history matters, as VW has refused goodwill on oil pump failures without one.

Only with bone-dry carpets, because water getting in is the B5's biggest known fault. Its plenum chamber drains block with leaves, the one under the battery especially, and on 1997 to 2000 cars that soaks the footwells, causes electrical failures and damages the ECU so the engine cuts out. On 2001 to 2005 cars the same water can rot through the brake servo, leaving a hard pedal or no assistance, and if it's drawn into the engine it can hydraulically lock it.
Cars from 1997 to 2000 have a known fault for front wishbones failing and rear brake seals corroding at around four years old, typically 40,000 to 60,000 miles, and recalls replaced the front lower wishbones on Passats up to 2001. Clunks from the front, vague steering and uneven tyre wear are the signs. On 2001 to 2005 cars the front wings rust through, and one owner of a 2004 car without a full VW service history had a rust claim turned down.
The 1.8 20v petrol is the engine to be wary of. Its timing belts have snapped at 70,000 to 80,000 miles and wrecked the engine beyond repair, early ones had plastic water pump impellers that fail, and paired with the 4-speed automatic it brings a whining gearbox. The TDI diesels are the better bet, with one owner's 1.9 TDI covering 305,000 miles with nothing worse than misting headlights, though dual mass flywheels have been failing on 2001 to 2005 diesels.

The electric handbrake goes wrong most, with more owner reports than any other Passat fault. Water gets into the caliper motors or the bearings inside corrode, so the brake jams on or won't release, and the switch can fail as well. One owner found a brake that jammed at 22,000 miles was only the switch and replaced it for £7, while another was quoted £500 when a rear motor housing split and let water in.
The 2.0 TDI PD diesels are the other big risk. On 2005 to 2008 cars with balancer shafts the oil pump drive fails at 80,000 to 120,000 miles and takes the engine with it, and owners have reported it at 61,000, 68,000 and 113,000 miles. The PD 170 from 2006 to 2009 has Siemens piezo injectors that short out and cut the engine, and PD engines from 2007 to 2011 can have porous cylinder heads that lose coolant.
Every 2005 to 2011 Passat also carries known faults for rear coil springs snapping, often after the car's been left standing, and one 91,000 mile estate broke both the first time it moved after months in storage. Software trouble in the power steering can kill the rack and leave the steering heavy, ignition locks have failed and immobilised cars, and air conditioning compressors have died repeatedly, three times by 50,000 miles on one owner's 2008 diesel.
Clutch judder on a B6 diesel is the dual mass flywheel failing, and it's been reported mostly past about 70,000 miles. Early 2.0 TDI DSGs held back pulling power from a standstill before surging forward, which catches drivers out at junctions, and the smaller engines' DSGs from 2008 have the DQ200 box. Even so, one owner's 2007 2.0 TDI DSG, given fresh oil every 10,000 miles and gearbox oil every 40,000, has reached 240,000 miles with a wheel bearing its one repair outside routine servicing.

Only after a careful clutch check on a manual, because the B7's most reported known fault is the clutch and dual mass flywheel failing at 25,000 to 50,000 miles, sometimes damaging the gearbox casing, and a failed slave cylinder often means replacing both. One owner paid £800 when a 2011 1.6 TDI's clutch failed at 27,000 miles, and a family with a 2013 and a 2014 Passat needed clutches, slave cylinders and flywheels on both at around 45,000 miles.
The B7's 2.0 TDI is the EA189, and its EGR valve and DPF have a known fault for failing at 60,000 to 100,000 miles after the emissions software fix, bringing limp mode and a flashing glow plug light. On 2013 to 2015 cars an in-line thermostat can also fail after that fix, leaving an engine that's slow to warm up. On a 2010 or 2011 2.0 TDI, a leaking fuel filter can soak the auxiliary belt until it shreds, tangles in the timing belt and wrecks the engine.
A 2011 diesel with stop/start is covered by a recall to replace the starter's solenoid switch, whose broken spring can leave the starter running until it overheats, and one owner who never saw the letter had his starter catch fire. Air conditioning compressors have a known fault for failing repeatedly on 2013 to 2015 cars, and the 2011 and 2012 1.8 TSI DSG uses the 7-speed dry clutch box rather than the sturdier wet clutch one that came later.
The B7's 1.4 TSI runs a timing chain rather than a belt, and those chains stretch and their tensioners fail, so a metallic rattle on a cold start means trouble. On the 2.0 TDI, the cambelt, water pump and tensioners want renewing every 60,000 miles or five years. One owner of a 2013 TDI had flooded footwells damage the comfort module, so clear the drains in the bulkhead vent well and check that the carpets aren't wet.

The 7-speed DQ200 DSG on 1.4 TSI and 1.6 TDI cars is the B8's biggest risk, with clutch packs wearing and mechatronic units failing at 40,000 to 80,000 miles. One owner's 2017 1.6 TDI estate went into emergency mode at 24,000 miles and still failed after a new clutch pack and mechatronic unit, and another's 1.4 TSI got stuck in third at 6,500 miles. A 2.0 TDI escapes that fault, and so does a manual, but a 2014 or 2015 manual has the clutch and flywheel fault instead.
Brakes need a close look on 2016 and 2017 cars, which have a known fault for rear discs corroding and wearing out between 14,000 and 36,000 miles, blamed partly on the electric handbrake and Autohold. One owner was quoted £800 to replace all four discs on a December 2017 car at 14,660 miles. On 2015 and 2016 cars, Autohold can also refuse to let go when you pull away, and garages have struggled to trace it.
A 2016 car with a sunroof has a known fault for water getting in, which has meant rewiring and dead steering wheel buttons, and one 2016 Alltrack needed that rewiring by 12,000 miles. The 2016 and 2017 1.4 TSI hybrid can suffer a failed switch in its high-voltage battery system that throws up a hybrid system error and has to be recovered because it won't start.
The 1.4 TSI petrol uses a long-life cambelt due at five years or about 120,000 miles, so ask when it was done on anything older than that. One owner of a 2019 1.5 TSI EVO complained about how it behaved at low revs in slow manoeuvres, got a software update and found it less responsive. Get proof of the 2017 recall that replaced airbags and seatbelt pretensioners that could fail to fire in a crash, and on a 2014 or 2015 manual, feel for clutch judder pulling away.

Volkswagen Passat Real MPG by engine →It's a comfortable, roomy car with very little wind or road noise, and the later ones are quiet and settled enough on the motorway to make long trips easy. The B7 is an easy-going car that's pleasant to drive, the B8 feels refined and relaxed at the wheel, and the B5 moved things on from the Passat before it, with more feel through the steering and a tidier gearchange.
The cabin's well screwed together and wears well, so a looked-after Passat can still look close to new years on. The B6's boot is big and its seatbacks lock, and the Alltrack's load bay opens wide over a low lip, which makes loading simple. There's plenty of engine choice, and tyres last well, with fronts going past 30,000 miles and rears past 40,000.
