Hey guys,

Need your help.

I have my CPO warrantied 335i at the local dealer for the P29F3 fuel pressure sensor code that is shadowing and won't clear; no check engine light. They just called and stated that it won't cause any issues and they have put that in righting on the receipt. Is this true that no issues will occur? I've heard that even though it's a shadow code, the ECU will still pull power/timing, etc. Don't know if this is true or not and just trying to figure out if I should make them change the fuel pressure sensor because of the code or just not worry about it. I do have a new AMS intercooler going on and Cobb stage 1+ tune and don't want to be losing power because of this shadow code or worse, hurt the engine, fuel system, etc.
