Daimler AG (DAI.ETR) announced that it will cut prices for Mercedes-Benz spare car parts in China by an average 15% starting next month amid a government probe into potential price manipulation in the auto sector, Bloomberg reported. The reductions will include more than 10,000 products covering all Mercedes-Benz models, with a 29% decrease on windshields, the company said in an e-mailed statement Sunday. Daimler has joined Volkswagen AG’s Audi brand in lowering prices on spare parts and the cost of after-sales services as China steps up scrutiny of the business practices of foreign companies.
