LEZ Frequently Asked Questions
Frequently Asked Questions?

How does the filter work?

A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.

How long does the filter take to fit, and how long will I be off the road?

Average fitting time for the filter is roughly two days. This includes taking the vehicle for an emissions test to gain the required L.E.Z certification.

What maintenance does the filter require?

The Clean Diesel filters are particularly popular as they require very little if no maintenance. Unlike other manufactures where the filter needs to be sent off to be professionally cleaned with potentially lengthy down times . We can carry out a yearly filter clean right in our own workshop at a convenient time to suit your schedule.

Other than the yearly clean all you need to do is keep the Platinum Plus fuel additive topped up. Simple!

What does the filter cost?

The cost of the filter varies according to each specific vehicle, but prices are usually in the region of £3250.00 per filter. (excluding fitting costs, and the initial L.E.Z certification.)

New partial filters have now been brought out and are suitable for use on most Euro II vehicles. These filters cost considerably less and would bring most Euro II vehicles in line with current emissions standards until 2012. For more information regarding these new partial filters and whether they would be suitable for your vehicle, please do not hesitate to contact our office for a free consultation and quotation.

Are there any running costs involved?

The beauty of the Clean Diesel filter are the low running costs. A one litre bottle of Platinum Plus fuel additive lasts for 3000l of diesel, and retails for roughly £50.00 a litre.
