2000 new beetle blue temp & air bag light

[VWbeetle2000]

My blue temp light is on every time my car is cold and eventually goes out when it warms up. I drive 20 miles to work traveling about 70 MPH when at about half way the light comes on or flashes for about a minute the goes off. Could this be related to the water pump?

As for the air bag light, I once read that it could be a loose wire under the seat. I believe that’s what happened to my car. There is no room for me to maneuver around. Does anyone know how to remove the seat or suggest a way I can get under there?

according to those symptoms i would suggest replacing the ect. its a common failure.

as for the airbag, pretty much 90% of the time there is a code for an airbag part its bad.
