The purpose of this blog is to log my Audi A4 problems and share the solutions I have found to those problems. Though this exchange we can all avoid the dealer and expensive repairs to common inexpensive problems.

Code P0171 System Too Lean (Bank 1)
Got the check engine light again, this time it was P0171 System Too Lean Bank 1. I had been meaning to replace some of the stuff on the vaccum system and thought I'd give it a quick look see if that could be the cause. Sure enough, I found a tear in an angled hose (AUDI Part Number: 058 133 783L). So I thought, ok, this will be easy, and searched for that part only to find that it had been replaced by (Genuine Audi/VW Part Number: 06B 133 783 BC). so I went to the dealer to get the part (normally I would have bought it online). I also bought an OEM clip (Oetiker Hose Clamp) to secure it, (Part Number: N10201901).
