Just received my second letter from Skoda requesting me to get the fix done for my Skoda Superb Estate. It's done just under 30,000 miles in three years. Given all the reported issues with the fix, I simply don't believe the letter which states, "I can be reassured that there will be no negative impact on engine performance etc..." Even if the EGR valve is likely to be in reasonable shape, there seems to be no upside for me in getting the fix done and only a potential downside, especially if I have to enter into a protracted debate with Skoda about post-fix reduced performance. What is the risk for me if I take no action on this? If there is risk, then how can I mitigate it proactively with Skoda?s
