Check a Volkswagen Transporter advert (free) →The Volkswagen Transporter has 8 known faults in our database, 4 of them rated high severity. The most serious are gearbox (DSG Mechatronic unit failure leading to loss of drive and erratic shifting) and engine (EGR cooler internal corrosion causing aluminum particles to destroy cylinder bores). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.
Sellers rarely admit these faults outright

They do not tell you whether this particular car has had the work: for that, put the registration into the free GOV.UK MOT history check, which shows a recall status where the manufacturer shares it, or ask a franchised dealer to check the VIN.
On affected vehicles the speed limit of 70 mph is not implemented as described in the technical data and stated in the vehicle registration document.
Put right by: Adjust the software in various control units.
On affected vehicles there is a possibility the rear axle shock absorbers could break.
Put right by: Check and replace the rear shock absorbers if necessary.
Urgent Safety Warning - Do Not Drive Your Vehicle Our information shows your vehicle was originally allocated to or used for an extended period of time in a region with a climate zone considered to as HIGH RISK. Issue: The front airbag in your VW vehicle contains an ageing inflator propellant that may explode when deployed due to long-term exposure to heat and humidity. Risk: If the airbag inflator explodes metal fragments may be ejected causing life-threatening or fatal injuries to anyone in the vehicle.
Put right by: The front airbag must be replaced. Immediate Action Required: Stop driving your vehicle immediately. Contact the Takata Stop Drive helpline at 0113 526 9646 (MONDAY to FRIDAY 9:00AM to 5:00PM to arrange your recall service.
The function of the driver airbag inflators can degrade due to air and moisture ingress.
Put right by: Replace airbag
There is a possibility that tyres could suddenly lose air.
Put right by: On the affected vehicles the production data (DOT number) of all tyres including spare wheel are checked and if necessary tyres will be replaced.
Possibility of humidity ingress in the Bowden cables of the doors due to missing seals.
Put right by: Remove cables and humidity and seal off. Poznan produced cables to be replaced.
Under very specific conditions the electric child lock is not mechanically locked although it has been switched on by the driver.
Put right by: On the affected vehicles the software of the on-board supply control unit has to be reconfigured.
Increased humidity may have got into the propellant of the gas generator for the drivers air bag.
Put right by: The gas generator of the front airbag on the driver side is replaced.
Due to an error in the manufacturing process the air bag and/or seat belt pretensioner may not trigger in the event of a collision
Put right by: On affected vehicles replace air bag assembly and seatbelt pretensioner where necessary.
On affected vehicles the near side front side air bag may have been incorrectly fitted in its module. As a result it may not deploy as intended during a collision increasing the risk of injury.
Put right by: On affected vehicles replace the nearside front side airbag.

An overdue cambelt is the most expensive thing a seller can fail to mention on a used Transporter. These are the figures UK specialists work to.
INA (Schaeffler) advises belt replacement on the Transporter 2.0 TDI common-rail family at 80,000 miles or four years. VW's own figures run to 140,000 miles with no time limit, but specialists hold to four years for Transporters given the loads they carry. The water pump should always be replaced at the same time.
The 7-speed wet-clutch DSG (DQ500) requires a fluid and filter change every 40,000 miles to prevent mechatronic failure and harsh shifting.
Sources disagree: continental listings give 120,000 km or a 5-year maximum, while UK T4 specialists quote 60,000-80,000 miles and 4-5 years. The shortest credible bound is recorded. The T4 2.5 TDI is also widely reported to run a second, rear fuel-pump belt that should be done at the same time; treat that as forum lore to confirm against the vehicle rather than established fact.
T6.1 (2019-2024) EA288 Nutz 2.0 TDI: DNAC 90PS, DNAB 110PS, DNAA 150PS, DMZA 199PS BiTDI. VW quotes a distance-only interval of 210,000 km / 130,000 miles with no time limit. UK van specialists widely advise a precautionary four-year / 80,000-mile change as on earlier Transporters, given the loads vans carry, so an older low-mileage T6.1 is not automatically in the clear.
The current Transporter (UK orders from January 2025, first vans from April 2025, Kombi and Shuttle from June 2025) is built by Ford on the Transit Custom and uses Ford's 2.0 EcoBlue diesel, badged 2.0 TDI. That engine runs its timing belt and oil pump belt in oil (a wet belt), unlike the dry belt on every earlier Transporter 2.0 TDI, and VW's own parts channel sells a 'Wet Belt Kit' for it. VW's own replacement interval for this engine was not found. Ford cut the interval for the same engine in its Transit vans from 10 years / 150,000 miles to 6 years / 100,000 miles in early 2024, because fuel dilution of the oil during DPF regeneration degrades the belt early, and that figure is recorded. Change the oil pump belt with the timing belt. The Multivan is a different vehicle with VW's own 2.0 TDI and is not covered by this row.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
Three stand out. Gearbox: DSG Mechatronic unit failure leading to loss of drive and erratic shifting (typically 80000 to 140000 miles). Engine: EGR cooler internal corrosion causing aluminum particles to destroy cylinder bores (typically 60000 to 120000 miles). Bodywork: rot in the lower sills, the sliding door step, and the bottom of the sliding door skin inside. The full list above is grouped by generation, with typical mileage and a rough repair cost for each.
No Volkswagen Transporter year is a write-off, but the T5.1 (2010 on) carries the most serious faults: gearbox and engine. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the gearbox, engine and bodywork faults on this page and whether they have been fixed, with invoices. On the test drive watch for PRNDS lights flashing on dashboard, excessive oil consumption (e.g., 1 litre per 1000 miles) and crusty or flaky metal along the sill seams and jacking points. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against all 8 known faults before you travel. Check a Volkswagen Transporter advert →
The DVSA lists 10 safety recalls for the Volkswagen Transporter issued between 2016 and 2026. The most recent, from August 2026, is "Correct speed restriction". Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it. This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.
Owners report 35.9 mpg on average across the Volkswagen Transporter engines with data, about 98% of the official combined figure. The gap between official and real-world economy varies a lot by engine, so the Real MPG page lists every engine and generation separately, from 17 owner submissions.
