Diesel return pipe

[Andy 110961]

Hi all I wonder if anyone has had this problem X.Trail Tekna DCI

the diesel return pipe blew a small hole in the pipe on the motorway driving at 60 miles an hour

Had it replaced by Nissan Guildford

Less than 15 miles return pipe blew again   Nissan re-ordered and got a new return pipe and now done less than 2000 miles same problem has happened again 

has this  happened to anyone or does anybody know the issue with this 

I will be turning it back to Nissan this week

How did you get on with it and what was the cause?
