2005 audi a4 2.0t fuel/performance issues p0089
Hello.
Trying to get some advice I have a 05 a4 2.0t Quattro and I'm getting a P0089 CEL, along with a misfire on no 2 cylinder I've replaced the fuel filter and ragulator, The cam follower, and the high pressure fuel pump. Have no power what so ever. I have had the p0089 code before and never had a noticeable performance loss. I think the misfire on no 2# is because of the p0089 code because all cylinders show great compression. Upon replacing my high pressure fuel pump I inspected the follower and camshaft. Follower was fine and cam shaft appeared to be ok as well. I'm just wondering where to go next. Any advice would be greatly appriciated

From what I'm seeing on the interwebs the code you mentioned is happening under load.
Found a thread here that suggests main fuel pump in tank as cause:
