Hi folks, before I start doing anything, can I ask can you take the egr valve off to clean while not bothering the cooler and fluid. My a6 is euro 5 2013 which seems easier to work on than the euro 6, would that be right. TIA billy.

Hi folks, just a wee update on where I am with the car. My a6 is a 2013 euro 5 which I think is easier to get at. Seems to be accessible from the top from videos I have seen on YouTube. New egr valve and cooler "valeo" seems to be no more than £300. Think that's the route am going to go. There's 1 torx type fixing to manifold that apparently is difficult to get at but can be done.

Would have a go, but keep reading it's a bugger to get at or is mine easier depending upon year, not sure. Is there anywhere on the forum that could help with that.

How do I know exactly what is the issue as code I'm sure was p0401, have deleted and hasn't came back on yet but sure it will return, said something like insufficient flow of egr. So is cooler OK?, is dpf OK? Does anyone know the codes for these parts. Or do you just replace everything connected with emissions. Obviously something is chocked but what to do. As for my original question or part of.. is an oil catch can worth fitting? Appreciate all comments and suggestions. Thanks billy.

Thanks for the reply steve, would replace egr and cooler but understand it's difficult to get at and expensive. Friend knows guy who blanks off egr and software deletes for £250. If car was newer or easier to get at to change over parts I would. It's a 63 reg. C7 2.0 tdi.

Hi, first of all thanks for letting me join the forum, look forward to hearing some informative chat and talking about audi's of which I love. My first post is a question regarding oil catch can, should I fit one on my a6 2.0 tdi c7 or not. I have the eml on and a code of PO401. Would it be of any benefit also was thinking of egr delete. Any thoughts appreciated. Thanks billy g.
