It could also be a duff battery......I know someone with an almost brand new range rover sport that kept flaggin up warning messages, parking sensors would go off for no apparant reason etc etc.  Took ages to track down but eventually they realised the current from the battery was dropping sporadically and causing the issues.  Worth checking out, cheaper than a new alt after all......

im from wales a place called abertillery not that far from cardiff
yes i think ill put a new battery on and check this
ive just come from a machanics house who just checked the voltage the alternator is putting through the battery and it came back 14.4v
so alternator looks ok unless its an intermittent fault
also the fault code on the vag com for the temp sensor and air flow is saying implausable signal
