I'm currently down a rabbit hole thanks to an issue with the EGR valve on my Caddy...
A week or so ago, I'd never heard of and EGR valve; now I see them in my sleep. Oh what a naive little thing I was, unaware of the horror that awaited me :D
Anyway, I have decided that EGR valves are heretical devices, and therefore must be cleansed. I've used my Ross-Tech VCDS for a fair few years, and am now going to embark upon the next phase of my evolution - EGR deletion via ECU flashing.
Looking forward to learning more (vPerformance vids have been brilliant thus far) and flashing my ECU so hard it will scream for mercy.
Currently am looking around to find the right MPPS dongle & flashing s/w, and plan on using EDCSuite for the programming part.
