Diesel vehicle values in 2026: low-emission zones in Europe
Diesel vehicle values in 2026: how low-emission zones and Euro norms across Europe affect diesel prices, where older diesels still sell and pricing tips.
· 7 min read
A diesel vehicle loses value fastest where low-emission zones shut it out and running costs punish it, as in Brussels and Dutch cities, and holds value best where zones are lenient and long distances favour diesel, such as Germany, Italy and Central and Eastern Europe. In October 2026, a ten-year-old Passat diesel was worth about €6,500 in Germany but only €4,500–4,900 in the Netherlands and Belgium.
Are diesel vehicle values falling in 2026?
Diesel values are not collapsing, but the market is splitting. New diesel sales have almost disappeared: according to ACEA, diesel took 13.6% of EU new car registrations in 2023, 8.9% in 2025 and 7.3% in January–August 2026. Fewer new diesels mean fewer young used ones, which supports prices for good, young diesel estates, SUVs and vans. At the same time, older diesels face more restrictions in cities, so their value depends heavily on where they are sold.
In practice, a diesel vehicle's value in 2026 depends on three things:
- Its Euro emission standard, which decides access to clean air zones.
- The market where it will be sold – the zones, taxes and driving distances there.
- Its mileage and condition, because many older diesels have very high mileages.
Which European cities restrict older diesel cars?
Clean air zone rules differ by country and often by city, and they change, so always check the current rules for your sales market. The main patterns in 2026:
| Country | Situation for diesel passenger cars |
|---|---|
| Belgium (Brussels) | Since 1 January 2026, Euro 5 diesels no longer meet the Brussels LEZ criteria; diesel cars need at least Euro 6. Non-compliant drivers can buy day passes (€35, up to 24 a year), and fines are being phased in during 2026. |
| Germany | According to the Federal Environment Agency, 35 environmental zones remain, all requiring the green sticker. Euro 4 diesels, or Euro 3 diesels with a particulate filter, qualify. Many cities have lifted their zones. |
| France | According to the ministry, 25 low-emission zones (ZFE) operated in metropolitan France at the start of 2025, with Paris and Lyon restricting Crit'Air 3 vehicles and above. |
| Netherlands | Municipal environmental zones (milieuzones) admit diesel cars by emission class; older diesels are excluded in the cities that operate a zone. Dutch road tax also adds a surcharge for diesels. |
| Italy | Several cities, Milan among them, run restricted zones with diesel thresholds that tighten in steps. |
The result is a patchwork. A Euro 5 diesel that can no longer enter Brussels can still drive freely in German environmental zones, most of Central Europe and the Balkans.
For car dealers
Know your margin before you buy
MyCarDealer compares any car from an auction or listing with the market in your country and shows the net margin after VAT, transport and costs – and the maximum bid.

Cars from 2012–2014 are mostly Euro 5 diesels, which makes them a good test of how markets value older diesels. According to listings tracked by MyCarDealer in October 2026:
| Market | VW Passat diesel 2012–2014: median price | Median mileage |
|---|---|---|
| Germany | €6,500 | 243,000 km |
| Czechia | €6,535 | 242,000 km |
| Bulgaria | €6,700 | 222,000 km |
| Italy | €6,500 | 240,000 km |
| Sweden | €6,150 | 239,000 km |
| Belgium | €4,900 | 227,000 km |
| Netherlands | €4,500 | 291,000 km |
| Finland | €4,990 | 315,000 km |
Belgian Passats were about 25% cheaper than German ones at similar mileage, which reflects Belgian and especially Brussels restrictions on older diesels. Dutch Passats were cheaper still, but with far higher mileage.
The Golf shows the same split between fuels. In Belgium, 2012–2014 Golf diesels had a median of €5,400 against €7,500 for petrol Golfs of the same years; in Germany the gap was much smaller, €6,750 for diesel against €7,390 for petrol. Diesels had more kilometres in both countries, but the Belgian discount was clearly larger. In Italy, 2012–2014 Golf diesels were at about €8,000, one of the highest levels in our data.
Why Dutch diesels are cheap and high-mileage
Dutch diesels follow their own logic. Dutch road tax adds a surcharge for diesel cars, and BPM charges a diesel surcharge at registration, so in the Netherlands mainly high-mileage drivers choose diesel. The result is visible in the data: 2018–2020 Škoda Octavia diesels in the Netherlands had a median of about 279,000 km and €9,950, against 150,000 km and €14,500 in Germany. Those cars are cheap for a reason, but well-documented examples can find buyers in markets that value diesels.
Where to sell older diesels: moving stock to stronger markets
Older diesels should be sold where buyers still want them, which is often not where you bought them. Options for dealers:
- Germany: environmental zones are lenient, and long commutes favour diesel. Good for Euro 5 and Euro 6 diesels with clean history.
- Italy and parts of Southern Europe: strong diesel tradition and high prices for well-kept cars, but check city-specific restrictions.
- Central and Eastern Europe: Poland, Czechia, Slovakia, Romania, Bulgaria and the Balkans still buy many older diesels, often imported. Check local registration taxes and rules for older cars before you price, for example in our guides on how to export a car to Poland or import a car to Romania.
- Export outside the EU: for very old or high-mileage diesels, specialist export buyers can pay more than domestic trade.
The point is to price a diesel in the market where it will sell, not where it stands. MyCarDealer shows the market price of the same model, engine and year in the dealer's own country and the margin after VAT and transport, so a dealer in Germany or Poland can see whether a Belgian or Dutch diesel is worth buying.

Should dealers still buy diesel stock?
Yes, selectively. Diesel still makes sense for these cars and customers:
- Young Euro 6 diesels in estates, SUVs and vans, for buyers who drive long distances or tow.
- Older diesels bought at a price that reflects the restrictions, sold into markets where they are still welcome.
- Commercial vehicles, where diesel remains the norm in the used market.
Avoid diesels whose only market is a city with a zone that excludes them, cars with unresolved emission-system faults and cars bought at prices from a few years ago. Check AdBlue and particulate filter systems carefully – our guide to AdBlue faults in used diesels lists the common problems – and see used diesel demand for the buyer side.
Frequently asked questions
Are diesel vehicle values falling in 2026?
Not across the board. Young diesel estates, SUVs and vans hold value because few new diesels are sold, while older diesels lose value in markets with strict clean air zones, such as Brussels. In October 2026, 2012–2014 Passat diesels were about 25% cheaper in Belgium than in Germany.
Can I still drive my diesel car after 2030?
In most of Europe there is no general ban on driving existing diesel cars. Restrictions are local: cities set clean air zones that exclude older Euro classes, and the rules differ by country. A Euro 6 diesel can enter most zones today, but city rules can tighten over time.
Which European cities restrict older diesel cars?
Brussels excludes Euro 5 diesels since 1 January 2026, Paris and Lyon restrict Crit'Air 3 vehicles and above, Dutch cities with environmental zones exclude older diesels, and several Italian cities, including Milan, run zones with tightening diesel thresholds. German zones only require the green sticker.
Where do Euro 5 diesels still sell well?
In Germany, Italy and Central and Eastern Europe, where clean air zones are lenient or absent and long distances favour diesel. Our October 2026 data showed 2012–2014 Passat diesels at about €6,500 in Germany, Czechia and Italy against €4,500–4,900 in the Netherlands and Belgium.
Is it still worth buying a diesel car?
For high-mileage drivers, towing and long-distance use, a young Euro 6 diesel can still make sense. For short urban trips, especially in cities with clean air zones, petrol, hybrid or electric cars are the safer choice.
