2006 b7 avant. The eml has come on...had it scanned and cleared. Same 2 issues came back. 1st is glow plug open circuit on all 4. Replaced glow plugs, and relay. Still showing codes when read and turning eml on, no idea what's goin on. Car starts fine every morning! 2nd is throttle position sensor. I've noticed when I use the car first thing, there's a slight judder under acceleration for the first few miles, then it runs fine all day long. Not sure if this is related, but it's not showing any other codes that could be causing this issue. Just this morning I've noticed the accelerator pedal has got like a notchy feel to it, and not smooth under my foot like it was. Sort of feels like it's clicking as I press it for power? Any my ideas what's goin on guys? Cheers for looking!
