Rossco Posted September 2, 2019 Share Posted September 2, 2019 Evening fellow Audi peoples. I have a 2007 A4 with the 3.0 TDI unit in and although its not thrown any error lights/codes I am going to replace the glow plugs as someones it takes some cranking before it starts when its cold. MY question is will I need to have the new ones programmed / plugged into VAGCom at all or can I just to a straight change - old school stylee? Thanks Quote Link to comment Share on other sites More sharing options...
