I am struggling to figure out, what should I say on a non-professional comment. Difference of opinion can exist between professionals which is normal and to me is healthy, as it brings out various aspects. However being judgmental on personal level is on low side ... and should be avoided. I am not here to throw out my CV of 22 years of work!
Can you please share your STEP-BY-STEP started thread which is written for PW community while considering STANDARD OEM procedures? (apologies in advance for asking this, as I am not a routine user on PW, so would like to see your technical contributions/articles and would like to learn from your valuable work shared here)
However, on positive side, your technical comments and efforts are appreciated (which need deliberation of course).
Secondly, this thread here is not to share Rules of Thumbs - rather to state OEM procedures. I have yet to come across an OEM procedure which directly jumps to conclusions!
A separate thread can be started on what is Calibration? In case if it is not clear to many people. How does a close-loop system if not calibrated could result into abnormal behavior will become very clear and how a calibrated system behaves will become evident.
Dear readers, please bare in mind few things whenever you encounter an issue:
Step-1: Never, ever jump to conclusion on first instance (the biggest mistake we generally make)
Step-2: Always follow the First-Principle approach. The OEM repair manuals always proceed with basic first principle.
NOTE: OEM Procedures ALWAYS make certain that an issue is 100% diagnosed before any repair work is started. (I see on daily basis that people are generally guided by hit and trial methodology)
Step-3: If choices are limited due to no access to reliable sources who can follow OEM procedures (which many dealership even wont do), always take the simplest and basic steps. Aggressive, approach leads to complicated issues. Many times sellers/mechanics etc want to go for profitable course, be very careful.
