I've got a vw phaeton 2005 3.0 v6 diesel with fault code p1545 throttle valve malfunction but there are 3 throttle valves 1 on each bank and another before the inlet splits into each bank any ideas?? Help!!

 

Hi, i would be tempted to say, if it was either of the flaps on the banks the code would suggest either "bank 1" or "bank 2"....
Im not a vw specific tech but that is fairly universal.
please dont take my word for this but it might be of some help....!

 

The simple way to detect which sender is at fault is to unplug it, see what codes are stored when you unplug each body, thats without me looking into your P code.
