xc60 d5 engine systemservice required message

this has been covered elsewhere but thought I shollud post this one

car has 148000 and fully serviced.
suddenly after a little wet Hebridean weather -the message appeared upon start up. no problems until this message and there was no turbo acceleration.
I took it to our excellent local garage who listed out 9 faults, yet when mechanic started car message disappeared and car is as good as gold- 50 +mpg not 38 over same route. turbo is instant no smoke and excellent response.

Mechanic view is possibility of a 'common wire' water ingress (which he described dealing with on double insulated wires on' 68 plate vehicles', leading to 9 ,yes 9 sudden fault codes.all are fuel/exhaust sensor faults.car parked facing into an 80 mph southerly with rain.
I think that when I parked at garage, engine heat hot enough to dry out the water ingress. On the road the airflow through engine did not have this effect.
any thoughts?
codes were P010000
P054600
P067400
P229368
P02E168
P054400
P208464
P0100000
P0E4600
mostly 'general faults' some 'signal too high or out of range' an 'algorithm error'
CAR LAST SERVICE 3 MONTHS AGO NO FAULTS OR PROBLEMS UP UNTIL THIS MASS READING!!
