Hello...I have a bad coolant sensor. Is this something that can be replaced easily? Is the sensor easily accessible? If so, can anyone tell me how to do this?

Thanks!

 

almost forgot...I have a 2003 A6 Avant 3.0.

 

What your statement is based on?
What are the indications for a bad CTS?

 

My friend has the software to do diagnostics on the car. He plugged it into the car to find out what was wrong. Here is the report that we got from it

Its not to bad of a job. All you have to do is remove the flex pipe from the mass airflow to the intake. The sensor is right down there. Unplug connector. Slide out clip. Replace sensor and o ring and your done. The procedure is pretty much the same as a 2.8 or 2.7, so if you find a writup on one of those you should be set.

 

I have the 2.8L 30v, and after a while the Sensor was done for and all the coolant was dripping.
I got this cheap one from a local car store and it was working fine.
But after a while the check engine light kees comming on and off, and i check the wires and see if anything is bad. most of the time i do that the light goes off again....... or when its really cold the light goes on ntil the car is warm.

Could it be possible i need to get an original part???
or is there something else causing the light going off and on


cuzz the one i am using is really cheap
