Hi, I feel like I need to give this original posters post a re birth as my car is doing the exact same thing. In October there it got a new HPFP after it went on me and it blew a fuse associated with the HPFP and or one that controls the turbo, after the HFP replacement it would stay in low power mode and it had lots of faults appearing it ended up with a new lambda sensor a new part associated with the turbo as apparently it was over fueling a bit and something else, anyway the garage had it 4 months I paid a fortune on that bill, I got the car back in October 2021 it had been driving fine since I got it back and now this! It just won’t start it’s ticking over but nothing and yes it has a brand new battery and I tried the bsi reset and still nothing, I’m waiting on the garage coming to collect it again to have a look but did this original poster get to the bottom of this fault ? I bought the car on 35,000 miles I’ve only covered another 5,000 miles over the space of a year and a half and the cars never done with issues. I have Lost all faith in it, I’m always thinking is this going to start ? Is this going to get me back home? I think if it gets up and running again I will be selling it as I’ve spent thousands on this car and it’s barely been driven :-(
