The check engine light (service engine soon) comes on and stays on when a problem is detected by the self diagnosis system of your vehicle. Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
yes there is and it has a light =)
yes
The 2010 Volkswagon Passat Wagan uses a gasoline engine.
I have driven a 2004 passat wagon that apon acceleration the car jolted and vibrated. Turns out the problem was the engine had a rod knocking and pretty much a bad engine, this could have been caused by a water pump or a oil pump not working. I would have a mechanic check it out right away.
The light should stay on whenever the key is on and the engine is off.
the normal running engine temperature on the passat is 195 degrees , most of the time the primary cooling fan gives out and they run somewhat warmer than that.a belt connects the primary and secondary cooling fans ! you may check the belt if your passat is running warm.

the sensor is going out
it could be your emission check sensor
Then you need to have the codes read with an OBD scanner.
you may need a new gas cap.i have a 2000
Volkswagen does not make a diesel version of the Passat wagon for sale in the United States. They have made a Volkswagen Passat BlueMotion Diesel that is or soon will be available in Europe only, however that is not a wagon.
