P2293 8p s3

Hey guys,

Recently did a HPFP internals upgrade on my car and this CEL popped up. Can anyone assist with this? My fuel filter was changed in December (and so was the entire HPFP), but after changing the internals this error popped up.

Worst is the car feels absolutely fine, throughout the rev range, which makes it harder to understand this error.

Please help?
Regards.

Is the car mapped for the upgraded internals? Did you change the cam-follower when you did the HPFP?

This is from the Ross-Tech site: http://wiki.ross-tech.com/wiki/index.php/18725/P2293/008851

I’d start by changing the cam-follower.

Its not tuned for the internals yet. The cam follower was fine on Saturday when we did the swap, but I'll check again.

Did some logging last night, and it seems the pump is failing to hit the requested fuel pressure, which is weird because the boost, and the afr requests are being met perfectly.

Could be the low pressure fuel sensor on the side of hpfp is shot.
