So my best friend is a tech at toyota. i asked him to get the low down on the cricket TSB the report to the A techs says , there is no fix if the customer wants a new fuel pump. basically in quick terms "there is no fixed fuel pump give them the brand new still shitty fuel pump" but yes being documented would be good. but he said realistically youll just be annoyed since it will be the same exact part.
id say wait a few months till a true fix has been made. thats what i plan to do.
i havent heard of anyone having engine failure or fuel system failure due to the HPFP to immediately need the fuel pump change. i read its the plunger that squeaks correct me if im wrong but it could just be a normal thing for the DI in this engine to do i mean i have heard this exact sound in VW 2.0T FSI engines.
again i could be incorrect. ill try to scrounge up some more info from the A techs when i get a chance.
