* Oct. sales helped by discounts, offset diesel ban -sources
* VW brand sales could be up 1-5 pct -one source
* VW declines comment, will publish U.S. sales on Nov. 3
BERLIN, Oct 30 (Reuters) - Volkswagen's sales of VW-brand vehicles in the United States have grown "slightly" in October, the first full month since the emissions scandal broke, two people familiar with the matter said.
The German carmaker is offering discounts on new models and other incentives in the world's second-largest auto market, which have helped to offset a sales ban on all 2.0-litre four-cylinder diesel models enacted last month when VW's rigging of emissions tests became public, said the people with knowledge of the sales data.
U.S. sales of the VW brand, due to be published on Nov. 3, could show an increase between about 1 and 5 percent, one of the people said.
He cautioned this "trend figure" could still change as dealers often don't report sales until the last day of the month, which still has two selling days to come. VW's deliveries were up only 0.6 percent in September to 26,141 cars.
A spokeswoman for VW of America declined comment.
Almost six weeks after it admitted using illegal software to falsify U.S. diesel emissions tests, VW is under pressure to identify those responsible, fix up to 11 million affected vehicles and convince regulators, investors and customers it can be trusted again.
The biggest business crisis in its 78-year history has wiped more than a quarter off VW's stock market value, forced out its long-time chief executive and tarnished a business held up for generations as a model of German engineering prowess.
Many owners of VW cars in the United States have switched from diesel to petrol-driven models this month with demand for the Passat and Jetta particularly strong, the people said. VW brand's diesel models accounted for 22 percent of last year's 366,970 U.S. deliveries. (Reporting by Andreas Cremer; Editing by Leslie Adler)
