This tells me it is EGR. The warning light is very intermittent, 115k miles, 6 months out of VW ‘goodwill’ post emissions fix warranty. Car runs absolutely fine. Presumably EGR needs replacing? Is deleting it beneficial? Downsides? Still on original DPF. 2013 B7 Alltrack 2.0TDI with DSG. Any idea of likely costs?
