Starting issues with warm engine

[Brooksfirm]

Apologies if going over old ground with this one.
We have a 2010 California SE with 19000 miles on the engine....yes it's correct.
We have noticed an intermittent fault when starting the van when the engine is warm.
We can drive for an hour, stop, then try and restart but the van won't start...engine fault comes up on the display with red battery light and flashing glow plug symbol.

Currently trying the second garage ( St. Eves in Bicester ) and they are a bit stumped.
They have changed the crank sensor as this was a possible.

Has anyone had this issue and actually found what the problem was ?

Thanks
Clive

What did the scan say?

 

[Brooksfirm]

Following codes

P0016-00 CRANK AND CAM CORROLATION
03021.12 LOCAL DATA BUS 3 ELECTRICAL ERROR
plus a parking sensors issue.

So did the garage do a crank/cam re-learn? Did they check the 5v ref signal?

They have changed the camshaft and crank sensors.
I will ask about the crank/cam relearn and 5v ref signal and report back.

Did the codes clear and not come back after the sensors were changed?
