V50 Diesel - P0099 Intake Air Temperature Sensor 2 Circuit

[Kikovuk]

Hi Everyone,
I hope that somebody here will be able to help me locate a IAT sensor and its part number.
My wife's v50 (2005) starts well but it feels a bit uneven while cold. I have used a code reader and it came up with
P0099 Intake Air Temperature Sensor 2 Circuit Intermittent/Erratic
and I was hoping that this is the cause of the issue.
My question is if somebody has had similar issue and if yes would you be able to let me know where this sensor is and what is the part number.
Many thanks in advance.
