I recently had an error code saying egr low flow, i was wondering if i needed a new egr valve, or can it just be some cloged hoses? I noticed that there are quite a few hoses splitting off various things in my 2.8 a4. Anyone have advice, and if i do need another egr anyone have one that they want to sell???...i reset the code and it seems to come back every 2 weeks to a month or even less than that.
