Take it back to the dealer. Probably a blocked EGR. The dealer is obliged to fix it. Volkswagen Group has sent letters out to Skoda owners to reassure them. It says: “if a customer makes a complaint to an Authorised Repairer or to the Volkswagen Group in respect of a failure of the EGR, fuel injection system or emissions after treatment system within 24 months following the date of the implementation of the technical measures, in respect of a vehicle with mileage not exceeding 160,000 miles, SKODA will consider the complaint very carefully and if such complaint was established to have arisen as a result of the implementation of the technical measures, then Skoda will act responsibly and swiftly, in line with its goodwill policy, as supplemented in the annex, to respond to the consumers’ reasonable concerns.”
