p246e exhaust gas temperature sensor 4 bank 1

[2008tdihighline]

Hi

I've got an error on my 2.0tdi cr, it's coming on and off with a ping on the dash every few seconds, how annoying!

The fault is p246e exhaust gas temperature sensor 4 bank 1

I've read this is after the dpf but unsure on a part number. Is there anyway to find out the part number? Also, is there just one sensor after the dpf?

I wanted to order the part an avoid removing the air box and intake pipes in this wet weather, only to have tto put it all back until the sensor arrives!

Thanks
