WLTP certification is causing a catastrophe for German manufacturers. It's not just the straight certification. It's because WLTP tests show a much more honest level of CO2 compared to the old NEDC tests, and where a manufacturer's corporate average CO2 is above the level set for the manufacturer it has to pay an EC fine of 95 Euros for every gram over the limit for every car. So, unless the manufacturer can increase its prices to cover that, it starts to lose money and that's why the Germans are testing and re-testing and testing again to try to get their cars through WLTP at lower levels of CO2. If you are not prepared to put up with this nonsense, cancel the deal and try to find a car that can actually be registered.
