Volkswagen Passat vs BMW 3 Series: The Honest Used-Car Comparison for Ireland (2026)

Put a used Volkswagen Passat beside a used BMW 3 Series in Ireland and the price gap looks small: about €2,000 at the median. The gap that matters is on the odometer. The typical Passat has done roughly 75,000 km more than the typical 3 Series — because most Passats were bought by fleets, and most 3 Series were bought by someone who wanted one.

Why is the mileage gap the whole story?

Fleet history. The Passat was Ireland's default company car for a decade — sales reps, pharma field staff, anyone doing Cork to Dublin twice a week — and those cars cover 30,000–40,000 km a year before they reach the used market. The 3 Series was more often bought privately and driven like a personal car.

That doesn't make a high-mileage Passat a bad one: motorway kilometres are the gentle kind and a serviced 2.0 TDI takes them well. But mileage is the first thing your own buyer looks at, so a 200,000 km Passat is always a slow resale, however well it drives.

• Passat, 2013–2015 cars: median €6,990, typically around 245,000 km, almost all manual.
• Passat, 2016–2018 cars: median €14,950, around 164,000 km.
• Passat, 2020–2022 cars: median €20,450 — but still around 211,000 km, ex-fleet cars off three- and four-year cycles.
• 3 Series, 2015–2018 (F30): median €17,833, around 134,000 km.
• 3 Series, 2019–2025 (G20): median €27,950, around 106,000 km.

What does €16,000 buy in each?

Set a budget of €14,000–€18,000, the heart of both markets, and they split cleanly.

The surprise is the fuel row: at this money the 3 Series stock isn't diesel-heavy, it's 320i petrols and 330e plug-ins, mostly 2016–2018 F30s.

A 320d does turn up under €18,000, from very high-mileage cars in the four figures to a tidy one at the top of the budget. What decides which you're looking at isn't the money, it's the build year: the F30 ran the chain-prone N47 from its 2012 launch to the mid-2015 facelift, and the better B47 after that. Both show up at this budget, so establish which engine is in front of you before you get attached. If you want a 2.0 TDI without waiting, the Passat is the easier find.

Below €10,000 the Passat is the more predictable buy: a 2013–2017 manual diesel at a median of about €6,990, on very high mileage. The 3 Series reaches down to that money too — usually an older diesel or a high-mileage 330e — but at this end you're budgeting for the BMW's bills, so put an independent inspection ahead of the purchase.

Which engine and gearbox should you look for?

Passat: the 2.0 TDI, and mind which DSG

Almost every Passat here is a 2.0 TDI (150 hp, occasionally 190) from the B8 generation (2015–2023) or a late B7, and the engine is sound at high mileage. The gearbox is where used Passats go wrong, and that depends on the box, not the badge:

• Seven-speed dry-clutch DSG (DQ200) — fitted to the 1.6 TDI and 1.4 TSI, and found on some early B8 cars. Mechatronic and clutch failures around 110,000–140,000 km are well documented: budget €900–€1,800 at an Irish gearbox specialist or €1,400–€2,800 at a main dealer (2026, VAT included). A specialist rebuild of the existing unit is almost always cheaper; diagnosis alone is €80–€180, so pay for that first. VW specifies no oil change here, so judge it on symptoms: juddering from a standstill, hesitation pulling away uphill.
• Wet-clutch DSG — the six-speed DQ250 on early 2.0 TDIs and the seven-speed DQ381 from the 2019 facelift. Far more durable, but it wants a fluid and filter change every 60,000 km. Look for the stamps, and confirm the gearbox code on the car itself.
• Six-speed manual — most of the cheaper Passats, and the least to go wrong. A manual median of €13,950 against €18,950 for an automatic is a big premium for losing a pedal.

One thing not to do: don't ask a dealer to check an EGR recall on a 2015–2018 car. There isn't an Irish one to quote, and the campaign numbers circulating online belong to the older EA189 diesel-emissions service action — a different engine family, replaced in the Passat by the EA288 for 2015.

Treat the EGR cooler as an inspection item instead: a cracked one lets coolant into the exhaust, so watch for steam or white smoke on a cold start and an unexplained drop in the coolant bottle. To have outstanding campaigns confirmed on a particular car, a Volkswagen dealer can run the VIN, and the Road Safety Authority publishes recalls by manufacturer for Ireland. Our Passat common faults guide has the full checklist; the Golf faults guide goes deeper on dry-versus-wet DSG, which is the same hardware.

3 Series: a 318d/320d from 2015 on, or a 330e

• 320d / 318d with the N47 engine (F30, 2012–2015): the rear-mounted timing chain can stretch and, at worst, fail. It sits at the back of the block, so access is what costs you: Autoza's Irish repair basis puts a chain-and-tensioner job at €350–€1,250 at an independent and €600–€2,250 at a main dealer, with an engine-out N47 at the top of both. If the chain has already let go and damaged valves, you're pricing an engine, not a chain. Put the horror stories in context: the failures that made this engine's name were the 2007–2011 units in the older E-series cars, the version BMW fitted to the F30 was revised, and plenty of F30s run to high mileage untouched. So don't rule one out. Cold-start it, listen for a metallic rattle from the back of the engine, insist on a full history with regular oil changes, and pay for an independent inspection. A documented chain replacement is the best thing in a history file — its absence isn't automatically a walk-away.
• 320d / 318d with the B47 engine (F30 facelift from 2015, all G20): the one to have. No inherited chain problem; the item to watch is a NOx sensor fault above 100,000 km. No Irish garage publishes a price for it — it's a sensor plus about an hour, and Irish labour runs €70–€110 an hour independent, €110–€160 at a franchised dealer, VAT included, so take one quote of each. Check whether it takes AdBlue too: BMW only made SCR with AdBlue injection standard across 3 Series diesels in spring 2018 (announced 17 January 2018), so every G20 needs topping up while most 2015–2017 F30s have no tank.
• 330e plug-in hybrid: the F30 (2016–2019) has a 7.6 kWh battery and about 40 km of electric range (BMW, NEDC); the G20 (2019–2023) has 12 kWh and 59–66 km WLTP; the 2024 update jumped to 19.5 kWh and 85–101 km WLTP. Winter range is lower on all three. Median asking price on Autoza is €18,950, across 2016 to 2025 cars.
• The ZF eight-speed automatic is on virtually every 3 Series here — a torque-converter box, not a dual-clutch, and it lasts provided the fluid is changed. BMW calls it lifetime fill. ZF puts no kilometre figure on it either: its own 8HP oil-change-kit service information gives no interval, and ZF Aftermarket says only to change the oil as set out in its lubricant lists, sooner on a car worked hard or towing, and to follow the manufacturer's schedule. So treat it as a job to do, not a date to diary: ask when it was last done on any 3 Series past 100,000 km, and budget €300–€650 for oil and filter at an independent, more at a dealer.

The 3 Series common faults guide covers the N20 petrol water pump and the gearbox selector module too, and there's 3 Series vs Audi A4 if you're weighing the other rival.

What do they cost to run in Ireland?

Day to day the two diesels are closer than the badges suggest. Motor tax is band-based, so a 2.0 TDI Passat and a 320d of the same era usually pay much the same. The 330e is cheaper again.

The band follows the CO₂ figure on the car's VRC and its first-registration date, so check the exact car with our motor tax calculator; full tables are in the 2026 motor tax guide. Insurance is the wildcard: Ireland has no official insurance-group table, premiums track the driver far more than the car, and BMW parts cost more when something goes wrong — our car insurance guide has the ways to cut it.

Space, boot, comfort — and the badge

This is where the Passat earns its keep. The B8 saloon's boot is 586 litres against the 3 Series saloon's 480 litres, and the 330e gives up another 100-odd litres to its battery, at 375 litres. Rear legroom follows: the Passat takes two child seats and a teenager in the middle, the BMW two adults who don't mind sitting close. A Passat Estate is the most practical car here.

The BMW answers with the drive — rear-wheel drive, a sharper rack, that eight-speed auto — and it holds its badge premium at resale. Depreciation is largely paid on both by now, so the gap between them is roughly what the market still pays for the roundel.

Verdict: which one should you buy?

• Family, two car seats, holiday luggage: Passat — a 2019-or-later 2.0 TDI with the wet-clutch DSG or a manual. Accept the mileage and put €350–€600 aside for an independent inspection and a gearbox service on day one.
• Long-distance commuter (Athlone–Dublin, Limerick–Cork): either, but a B47 320d (2016 on) is the nicer place to spend two hours a day. If the budget stops at €15,000, the Passat 2.0 TDI is the safer diesel.
• Dublin driver with a driveway: a G20 330e. Charge nightly, do the M50 crawl on the battery, and tax it for €140–€170 a year.
• You just want the BMW: fair enough — buy a post-2015 B47 diesel or any G20 and insist on full service history. An early N47 car isn't a write-off, but don't buy one on looks: cold-start it yourself, and spend money on an inspection before you spend it on the car.

Repair costs come from Autoza's Irish repair-cost basis: verified 2026 Irish labour rates (independent €70–€110 an hour, franchised main dealer €110–€160, VAT included) plus Irish parts and specialist pricing, cross-checked against Irish gearbox specialists including Euro Clutch & Gearbox Centre, Dublin 13, who quote on request rather than publish list prices. Every figure is a range across an independent and a main dealer, because the two are genuinely far apart — and where there's no Irish price and no defensible way to derive one, we say so rather than print a number.

Frequently Asked Questions

Is a used Passat or BMW 3 Series cheaper in Ireland?

On Autoza in September 2026 the median asking price is €15,950 for a Passat and €17,999 for a 3 Series — about €2,000 apart. But the typical Passat has around 195,000 km on it against about 120,000 km for the 3 Series, so the BMW is the lower-mileage car per euro. It is not the newer one, though: at this budget the Passat typically runs 2017–2021 against the 3 Series’ 2015–2018. You are choosing a younger, harder-worked Passat or an older, easier-lived BMW. Most Passats were fleet cars driven 30,000–40,000 km a year.

Which Passat DSG gearbox should I avoid?

The seven-speed dry-clutch DQ200, on the 1.6 TDI and 1.4 TSI and some early B8 cars: mechatronic failures around 110,000–140,000 km cost €900–€1,800 at an Irish gearbox specialist and €1,400–€2,800 at a main dealer. The wet-clutch boxes on the 2.0 TDI (DQ250, DQ381 from 2019) are far more durable if the fluid was changed every 60,000 km.

Is the BMW 320d reliable as a used car?

The B47-engined 320d (F30 facelift from 2015 and every G20) is a solid high-mileage diesel. The earlier N47 (2012–2015) has a rear timing chain that can stretch and, occasionally, fail — €350–€1,250 at an independent or €600–€2,250 at a main dealer, at the top of both when the engine has to come out. BMW revised the chain after the 2007–2011 cars, so on an F30 it's the exception rather than the rule. Listen for a cold-start rattle from the back of the engine and get an independent inspection rather than ruling the car out.

How much is motor tax on a Passat 2.0 TDI vs a BMW 3 Series?

Most 2.0 TDI Passats and 320ds registered 2008–2020 pay €200–€280 a year, with the majority at €200 (Band A4). The 330e plug-in hybrid pays €170 if registered up to 2020 or €140 from 2021 on. Check the CO₂ figure on the VRC to be sure.

Is the BMW 330e worth buying used?

Yes, if you can charge at home and most trips are short: the G20 (2019–2023) is rated at 59–66 km WLTP on electric, the F30 (2016–2019) at about 40 km. Median asking price on Autoza is €18,950. Have the battery health checked, and note the boot shrinks to 375 litres.
