"Warning light of exhaust emission control system" lights up frequently. What should Passat do?

Compared with B5, Passat's overall dimensions are slightly increased in length and width, with the length increasing from 9mm to 4789mm and the width increasing from 25mm to1765mm. . The height and wheelbase have not changed, and they are still 1470mm and 2803 mm.

Because the overall size has not been greatly changed, the interior space of Passat Yu Ling has not been updated, but even so, Passat Yu Ling is still the largest in its class.

The first Passat Yu Ling models listed are 1.8T and 2.8V6, and the 2.0 model will also be listed in 2006. In order to meet the increasingly stringent domestic emission regulations, Passat's engine has been upgraded to Euro IV standard. The layout of the engine room is still the same as that of the B5 era. Like the support system of the luggage compartment, the hydraulic tappet support of the engine cover has not shrunk into a metal hard rod, which shows the rigor of the Germans.

The dynamic parameters of 1.8T and 2.8 V6 engines remain basically unchanged. If you look at the parameters carefully, you will find that the maximum torque range of 1.8T engine increases slightly, while the fuel consumption of the two engines decreases slightly with the increase of vehicle weight at the same speed of100 km/h.
