I've performed a search and read the threads, but I'm still in the dark on how to locate the egr tube to clean. What does it look like (diameter, length, connected where?) Where would I remove it to clean it out, etc. Do you access it from the top or do you need to get underneath the car? Also for reference what does the egr valve look like and where is it? I'm asking all these questions to demonstrate my cluelessness on this.

If I'm looking into the engine bay what side is the tubing on and do I have to remove anything to locate and/or see it clearly? Please note that I'm still a little vague on the engine layout and as to which side is the intake and exhaust side. Thanks.
