Fault Code 01314 Engine Controller Spurious Comms Intermitt

Hi, as per title line, car is a late 2009 Ibiza 1.4 SC.  What happened was, after a 75 mile run with no problems, when nearly back home, I noticed an indicator light flashed once and some relay(s) gave a single chatter - nothing else happened.  When back home I checked which indicator lived in that area of the revcounter and discovered it was the engine management fault indicator.  Scanned the car with VCDS and found a single fault, ie 01314    004 and that fault only occurred once, cleared fault, checked seating of all fuses and relays and engine ECU connector - all okay.

I've checked on the internet and mainly any questions asked about this kind of get ignored or at least no definative answer(s) offer as to the real root cause of this.

So, any one else had this or heard about someone having this fault logged?  Ta!
