my doblo starts fine from cold, will tick over and rev on the drive way all day long, but 100 yards of putting it under pressure it dies engine light comes on and struggles to restart.

had diagnostics machine on get codes p1447 and 1448

spoke and had the injectors out and tested by a diesel centre 2 ok 2 u/s so replaced the 2 u/s started first time and then done exact same thing

its had filters and a fule diesel system clean out any ideas where to go next as i aint got a bottomless pit
