2015 CT 135k miles, EGR?
I have had my CT for a little over 2 years now, bought it at 100k. I know that my year, upon some research, is somewhat more tolerable to head gasket issues, etc. Anyways, when I bought the car originally, I knew very little about Toyota hybrids and the maintenance that is required. The guy gave me a list of what he did, and I believe he may have cleaned the EGR. I really just didn't know what that was at the time, and I can't seem to find his contact to ask him. The car runs like a dream and has had no issues whatsoever. My question is, considering a shop is charging $170 just for a diagnosis, what is the easiest way to tell that the EGR needs to be cleaned, or otherwise left alone? I know the pipe can be checked. I am decently mechanically inclined (changed oil, brakes, etc.). Any help would be greatly appreciated. Thank you
