Hi all, I am new to this site and wondering if anyone could help with the following fault codes, p0403 - EGR valve (N18) malfunction - intermittent and motor for manifold intake flap (v157) malfunction P3103. The car has the engine management light on, it idles a little bit rough, and intermittent power loss.

It is due to go in on Friday for further diagnostics but if I could get any idea what this could be prior to me taking it in that would be great, codes were taken from a snap on computer.

Welcome to VWAF :)

The first place to look for any fault codes is the Ross Tech (the makers of VCDS) Wiki.

The next place is our forum

The "check engine" light came on today.... (http://www.vwaudiforum.co.uk/forum/showthread.php/160625-The-quot-check-engine-quot-light-came-on-today)

Good luck :)
