Help with my OBD codes

[Aleisa]

Hi,

I just got a MK5 GTI FSi (123K Mi) and I didn`t even inspect :yikes:
Checked with Dealer and told the last official service was done is the 46k mi.. :smile:

but I used the ScanGauge II and it shows the following codes:

B3800
B0800

C0400

P0004
P0007
P0008
P014D !!

Now, this the parts list I am fishing from the Internet (so far):

ENG OIL FILTER = 06D115562
ENG AIR FILTER = 06F133843A
AC FILTER
ENG OIL HOUSING= 06D115408B
T CUT OFF VALVE= 06H145710D
ENG oil cooler GASKET= 06F-115-441
ENG oil cooler GASKET= 06D-117-070
H Pressure Fuel Pump= 06F-127-025-M
Engine Oil Drain Plug= N90 813 202
Engine Oil = Liqui Moly 0W-40 Synthetic Motor Oil

For the "T CUT OFF VALVE 06H145710D" I got the "dv+ Blow off Valve or BOV T9351"
I thought it`s a good idea to do it at the same time..

Now I am kind of lost :iono: Help please..

Hi. I can help a little by explaining some of your fault codes...e.g.
P0004-Fuel Vol. Regulator control circuit high
-The fuel volume delivered by a pump can be controlled by a volume regulator, the regulator will be operated by an actuator. eg. solenoid. On common rail systems when fuel demand is low...(at idle) one of the three pumping elements in the high-pressure pump is disabled by the action of the solenoid.
-Possible fault with the regulator or wiring, a short, open circuit, or resistance that is causing a signal value to be higher than the maximum operating limit. The control unit could be providing the correct signal but is being affected by the circuit fault.

Unless you've got them already.
