I have had the same issue for the past year. I started adding fuel additives and light goes on/off now. thankfully it hasn't gone into limp mode. There are many additive products out there. Hotshots and Archoil is the better of them all in my experience.

That rail pressure code comes from restricted fuel filter.

Thanks for the reply. I change the fuel/water separator every time I change the oil (7K). Been using Hotshots fuel additive on every fuel fill up. I have an oil/fuel filter change coming up soon hopefully the fresh fuel/water filter helps
