Hello, I'm new around here so your help would make my day. ?
I have a Golf MK5 1.9 TDI 77kw BKC engine 2005 with 135 thousand km.
I have an engine light and my obd diagnostic says P0401 insufficient air flow (something like that).
I cleaned the egr and the pipe that goes from the cooler to the egr and the light is back. The egr is working fine.
Any advice or solution would be helpful. If i missed something i will add it to the post.
