Pulled over and put gap tool on it.  Emailed the codes to myself and cleared codes.  It drove home the 6km or so ok.
- P000E-22 (68) Fuel volume regulator control exceeded learning limit - General signal failure - signal amplitude>maximum
 - P0087-00 (2C) Fuel rail/system pressure - too low
 
These really worry me as the little research I did indicates anything from clogged fuel filter to failing HPFP.
I have never had this issue before and have had the D3 since new.
Keen to know thoughts of others who may have experienced this one.
thanks
cheers

 How many kms? Normally about 250 k kms. 
I believe you’ve just received your first unwelcome membership invite to the failing hpfp club. 
Definitely check lp side and fuel filter. 
Mine started like this in the April and went off two or three times fast requiring pulling out of traffic in limp mode and access height. 
It then did not reappear for months until I gave up around the next January and changed it. 
I eventually caught it on the Gap tool by monitoring the PCV and VCV functions (BradC is the absolute expert) and you see failure of one of these to react at the time of the fault. 
Definitive proof is hard as it could fault 5 minutes after the first one or maybe not for months meaning driving with the Gap tool running. 
It’s not such a bad job to replace. A lot of finger gymnastics.
