So my A3 2007 2.0tdi quattro has suddenly started displaying the emissions control system light..
This happened last friday.. and after a VCDS scan it shows:
16785 - EGR System
P0401 - 000 - Insufficient Flow
No loss of power, infact i would say its perfectly fine.. i cleared this and the light went out - drove a full week (roughly 150miles) and its just triggered a light again.. my trips are fairly long (motorway too)
Any ideas?
