Hello Everyone,
Looking for any ideas on what my issue may be.
last week when joining the motorway when i put my foot down the revs started "surging" (revving up and down when foot on pedal) while loosing power and blowing some white smoke out the back. Pulled on to the hard shoulder managed to get it started but it doesn't stay started for long and was unable to drive it away so got recovered.
The day after i plugged my laptop in to read any codes and got the following (Ignore the MAF that was me unplugging it)

The garage has inspected my turbo and said its fine and that more investigation needs to be done to find the issue, they cant get onto it yet due to being too busy.
I'm hoping that someone on here has some experience with the issue.
My thoughts... Lift pump in the tank failed? it does start with difficulty but is rough and doesn't stay started for long, almost like it isn't getting the fuel it needs. Doesn't throw any codes though and I cant get back to the car at the moment to do any VCDS logs. I say lift pump as it had a new tandem pump a few months ago for suspected seal failure.
Other thing could be injector seals ?
Any help with this would be much apricated, it would be good to have a few ideas before I go back to the garage.
