Hello
I got a 2010 T5 Whit a CAAC enging. Every now and then it goes into limp mode and the glowing light is flashing. VCDS autoscan says P0087 fuel preassure to low. Ive been struggeling whit this problem a while. Last week i meassured return flow on injectors. The walues where to high and i replased all injectors. They are all coded inn ECU, so thats ok. The car is much better now, but it still goes in limp mode when i drive 30-40 km. Its enough to stopp/start, and it goes well a long time. Does anyone have some tips for mee?
Just so its said, the fuel filter is new and the low and high preassure pump is also replaced ( privious owner )

Has the feulfilter been replaced recently, before the first time the DTC showed up?

Preform a test drive and check the requested high pressure and the measert high pressuse. The best way to check that, is to go in 3rd gear, a low rpm (+/-1000) and give full throttle.
Please report those findings back

That is correct, as soon the ECM detects an rail pressure error its goes in to limp home as an safety. Please post the log of the pressure during an testdrive to see what happens.
