This EGR issue is close to moving me from fleet purchase of VW group cars over 30 years. I have always run VAG group. My wife's seat 40k 4year 1.6tdi light has come on - egr code reset and cleaner has done the trick for now. Just test drove a similar age same engine skoda from a dealer - fault light came on during test drive and new egr valve needed! One hundred percent of cars in sample of two cars does not bode well?!
