Hi

Recently I've been having few issue with my 3.0 tdi (2006) its lost power, so I did a scan its coming up with the following codes.

004120 - Intake Manifold Runner (Bank 2)
P1018 - 001 - Lower limit not reached - Intermittent

005660 - Glowplug for Cylinder 3 (Q12)
P161C - 001 - Open Circuit

005495 - Right Engine Mount Solenoid Valve (N145)
P1577 - 001 - Open Circuit

013128 - Control Circuit for Controller for Turbocharger 1 (J724)
P3348 - 004 - Electrical Malfunction

The car been back to the dealer where I bought the car from they told me its was a electrical fault in the wiring loom. The dealer sorted the issue the car drove well then all gone wrong again. I scanned the car again all the codes are back. I'm not sure if this a electrical issue or I need to replace the faulty parts.

If any suggestions all the advice will be appreciated.
