2007 audi q7 fuel pressure fault

[Amy82r71]

Hi everyone. 

I'm new, please be kind.

So 17 weeks ago a purchased an audi q7 sline 3L 2007 reg. 16 weeks ago it died and wouldn't turn over. It had 4 mechanics scratching their heads at what the fault could be, fast forward and we finally changed the ecu unit in the engine. The car now runs, however... It gets to 3k revs and goes into limp mode and gives a code of p1063 for the fuel pressure. My mechanic is at a lost and I don't have thousands to throw trying to play guess which part has broken today. 

I'm gutted, stressed and without a car. Has anyone had this fault or known of this fault and what it could possibly be? So far I know the mechanic has checked the injectors as that was the initial fault code before the ecu was changed. 

 

Love, a distraught female audi owner.
