I have been experiencing problems with my 2005 A4 B7 3.0 Tdi. The Turbo will stop boosting intermittently. I have had a diagnostics report run and the code P3348 keeps popping up, turbo charger module. I have bought and had fitted a new actuator at a AD but it was no different, it wouldn't calibrate or accept they advised new turbo and actuator ££££££££. I have commenced the task of removing the turbo to give it a once over and replace if necessary myself but after removing all bolts and ancillaries I just can't get it out. Does anyone know what else I will need to remove or unbolt in order to be able to remove the unit. I am being assisted by a friend who is an Audi enthusiast and has worked on and removed many engines and turbos but we just can't prise it out. Please Help. Thanks in advance.
