Mack04 Posted June 1, 2013 Report Share Posted June 1, 2013 Just had me A6 3.0TDi Quattro (C6) back from its service from Audi and i asked them to look into it smoking under acceleration, the result is they had suyggested that i replace the ERG valve at £480. Just wanted to ask is this part CP protected? Link to comment Share on other sites More sharing options...
cruiser647 Posted June 1, 2013 Report Share Posted June 1, 2013 Probably best to try and clean it youself with Wynn's Carb Cleaner. Give it a go. Will probably be a bit of undoing of stuff first to get to it though. Will try and look it up for you in ETKA. Link to comment Share on other sites More sharing options...

Mook Posted June 3, 2013 Report Share Posted June 3, 2013 I'd look to remove the EGR valve and get the ECU updated so it ignores any errors. The EGR does nothing for the car - it's a Euro emissions necessity. Get the car remapped while you're at it - talk to Ben at Shark Performance (not too far down the road from you in Mansfield) about doing both for you at once Link to comment Share on other sites More sharing options...
Mack04 Posted June 10, 2013 Author Report Share Posted June 10, 2013 Cheers Mook, will this reduce the black puff of smoke under acceleration? Link to comment Share on other sites More sharing options...
gupsterg Posted July 28, 2013 Report Share Posted July 28, 2013 (edited) Just wanted to ask is this part CP protected? EGR valve have no CP ... there are 2 variants of EGR valve as 2004 - 2009 EU4 V6 TDi has a vacuum EGR valve, the 2009 - 2011 EU5 V6 TDi has a electronic one ... google for ssp 350 , this is the EU4 V6 PDF, view pages 30 & 31 ... google for 3000cc V6 TDI Audi , this is the EU5 V6 PDF, view pages 20-22 & 66 ... As I have a 2005 3.0 V6 TDi and am also doing some intake/EGR work to car here's a video of a new valve ...
