Diesel vehicles can potentially be converted to meet Euro 6 emission standards. Because a large part of the process to reduce harmful gases takes place in the exhaust system, it’s a more viable option.
Converting older vehicles to Euro 6 only really makes sense for commercial vehicles
But while you could potentially upgrade any diesel, it doesn’t make sense for most motorists. It will add weight, require substantial space around the exhaust system, and the cost is likely to outweigh the benefit.
That’s why most conversion services and products are aimed at the commercial market, particularly larger and more expensive vehicles. SCR systems range from around £1,200 to £3,000.
There’s also an issue that there’s no current certification for retrofit systems. So it’s difficult to know whether or not your work will result in a Euro 6 compliant car. Or whether the work will be recognised by authorities operating the low emissions zones in the UK and Europe.
In Germany, the transport ministry has released guides for getting regulatory approval on retrofitted exhaust systems, with Volkswagen and Daimler offering to cover some of the costs. But in the UK, the focus so far has been on upgrading public vehicles including buses and black cabs.
Ultimately if you’re considering converting an older diesel to meet the Euro 6 emission standards, it’s probably worth waiting if possible. As it becomes a more common need, the process should become cheaper and easier. But at the moment, it’s hard to justify on practical and financial grounds.
