Toyota's scrappage scheme is slightly different, being open to vehicles more than seven years old and in customer ownership for at least six months.
This offer can be used on top of any other offers from the dealer/manufacturer/finance company.
Customers can access Renault's offers of either 4.9% APR PCP or 0% APR hire purchase along with two years free servicing on cars or 0% APR hire purchase with four years free servicing on vans.
This scrappage scheme is the first to promise that these older diesel vehicles traded in will be taken off the road and scrapped. Similar scrappage schemes have been launched for Audi, SEAT and Skoda cars.
Discounts range from £2,000 off the Aygo up to £4,000 off a Land Cruiser - with additional savings made when twinned with the plug-in grant.
Alison Jones, director of Volkswagen UK, said: "With this new Scrappage Upgrade scheme, there's never been a better time to step up from an older diesel into one of our new, lower-emission range of Volkswagens".
The scheme starts from September 8.More news: Masked Anarchists Attack Pro-Trump Demonstrators in Berkeley

The other auto firms are offering discount incentives on old diesel trade-ins but are likely to sell on these cars to used-car buyers.
For September only, drivers of vehicles registered before the end of 2009 with a pre-Euro V engine can trade the vehicle in to receive up to £5,000 plus a trade-in value for the current auto off a new Nissan passenger auto model. From Friday, a more gruelling "WLTP" test on one of these devices is being implemented, which will be supplemented by a "RDE" test on the roads, meaning the new regime will give a much more representative measure in emissions and efficiency.
Hyundai has said that all Euro 1-3 cars they receive will be scrapped, while owners of Euro 4 models will be able to simply trade them in without having to commit their auto to being destroyed.
For the electric cars in the firm's range, such as the eGolf, when combined with the other grants on offer there is €14,000 off the official list price.
Vehicles registered before the end of 2009 with a pre-Euro 5 engine qualify for the scheme, which runs from September 1 to September 30.
Toyota confirmed that the scrapped vehicles will be handled at authorised treatment facilities, and at least 95% of the auto components by weight will be recycled.
Meanwhile, the marque's plug-in hybrid and fully electric models are leading players in the EV world.
