Q: EGR valve

asked by on November 19, 2016

I replaced the EGR valve, but the value I used was cheap so I'm planning to replace it with a better valve.

Anyway, I was told by a mechanic that a diagnosis computer is necessary after installation.

My question is how true is that statement?

My car has 80000 miles.
My car has a manual transmission.
