Volkswagen has said the number of its cars affected by inaccurate fuel consumption and CO2 emissions measurements is much smaller than first thought.
The German firm admitted last month that levels may have been set too low for 800,000 of its vehicles, but following further investigation, the company has revised the figure down to 36,000.
VW issued a list of nine affected models, including Polo, Golf, Jetta and Passat models.
It released a statement which claimed the deviations found in these vehicles “amount to a few grams of CO2 on average”.
The company claimed the estimated negative impact of g2o billion (£1.4bn) “has not been confirmed”.
The carbon issue has deepened the crisis engulfing VW, which began when it admitted installing software designed to cheat emissions tests for nitrogen oxide in diesel cars.
Some 11 million vehicles globally were fitted with the defeat devices, almost 1.2 million of them in the UK.
This led to the resignation of CEO Martin Winterkorn and car sales fell by almost 20 per cent in the UK in the wake of the scandal.
There were 12,958 VW registrations last month compared with 16,196 in November 2014, the Society of Motor Manufacturers and Traders said.
VW has set aside g6.7bn (£4.8bn) to deal with the controversy.
