Cars will break, parts will fail. Replace them when they fail. Again, don't replace your engine because you need new oil in it. Sure, it all works together as a whole, but I personally would rather just replace the oil. I guess just my personal preference. The only time I recommend buying extra parts is when I'm already far into an engine and it will save a lot of money in the future. For example. If I do a timing belt, I recommend replacing cam/crank seals and water pump instead of charging another 7 hours later if those items fail before the next 90000 miles.

Acts of carelessness, however, may cause the knock sensor to get damaged. Running the vehicle using fuel with much higher volatility or much lower octane ratings than what is recommended by the vehicle manufacturer are among those things that may cause knock sensor failure."
"Many factors can cause such detonations. Among them are too much carbon deposits on the cylinders, spark plugs that are too hot for the engine, high combustion chamber temperatures, and too advanced spark timing."
Many factors lol not
can be related to the egr..but more than less its main funtion is to protect engine from detonation error due to timing issues
so if egr primary function is to do this.. its safe to say that egr/knock sensor failure more than less are 2 seprate part failures rather than part failure do to other parts...unless timing and basic engine function is an issue

You said it all right here, but I'm not sure that you put it all together. I agree that they are two different systems, but even you said detonation can be caused by high combustion chamber temperatures. I agree. EGR lowers combustion chamber temperatures. We all agree. Therefore, it is possible that a non functional EGR system will cause detonation and cause the knock sensor to behave how the ECU might determine erratic (I'm not sure what the parameters are on the KA knock sensor code). I agree with you completely. I'm not sure if you realize you agree with me though.

The only reason I let you know about my ASEs is because you seem to hold them in such high regard. And I'll quote:

You brought it up, not me.
