I wired in an ammeter into the fuel pump to see when it was kicking in and found that its off most of the time for motorway cruising at low speeds but put your foot down or even starting a slight incline when you see the instantaneous fuel figure on the computer dropping and it kicks in straight away . This might not be your problem but worth keeping in mind . My Bosch pump was replaced with a Denso pump from an old Toyota , its been running for 28k miles with no problems .

That's quite interesting. At what RPM usually your car went into limp mode? Mine appears at around 3500-4000 RPM and I know that's when the turbo governor opens the bypass for the fumes in turbo. So it might be something with my turbo but I'll have a look at the pump too.

After replacing it, it still regularly came disconnected and I would get the message again whenever I put a high load on the engine.

I think that with the newer models the modified the swirl arm but I'll check that as well. Thanks

It's the same in my case. After restarting the engine everything works fine back again.
