Looking For MKV GTI ECM Pinout

Flame me if you must.

I have searched high & low, I cannot seem to locate a wiring diagram for the ECM.

I can find diagrams for just about every other model except the MKV.

2008 GTI FSI BPY

Have several codes indicating an open circuit, bad ground, low voltage for several components.

I assume they have a common Reference Signal & Power Supply, but cant be sure.

Someone has to have a mitchell diagam or alldata diagram?

Dont have access to VCDS, running this repair with a generic scan tool for the moment.

Just for fun, the components mentioned are...

- P2294 : Fuel Pressure Reg #2

- P0657 : Actuator Supply Voltage A

- P0458 : EVAP Canister Purge Solenoid

- P0245 : Wastegate Solenoid A

- P2401 : EVAP System Leak Detect Pump CTL Circuit

- P0031 : HO2S B1 S1 Heater Circuit

- P0036 : HO2S B1 S2 Heater Circuit

Car has the dash lights on, obviously.
Car has 0 boost
Car is in limp mode
PRNDL Flashing
Runs like a pile right now.
Oh & Misfire all cylinders.

I suspect a charging system or battery supply is partially at fault, Mmmm but, I can guess I have another issue or 2.

The Story (because its fun reading)

As a hobby, I often find busted Volkswagens & fix them.

This 2008 only has 70,156 miles! I was like no way can I let this GTI hit the salvage yard it deserves better.

So here I am, looking for wiring diagrams, I will update this thread as I move along.

Has been in a front end collision, wiring & sensor damage are probable, although the body damage had been repaired.

Basically looking if the Diverter Valve, HPFP Valve, EVAP Can Solenoid, O2 Heaters share a circuit from the ECM.

Thanks.

any luck?

Just curious if you ever found the ECU pinout map? I'm having an issue on a 2008 GTI FSI BPY. Trying to figure out where pin T60/19 is, as is it seems to have a voltage drop (2.48v's) on the negative side from the N276 solenoid. Hope all is well and thanks!

I have a 2007 MK V GTI. I'm chasing a trouble code for fuel pump relay short to ground. Hopefully I'll find the source and get it running. I bought this one from an impound lot at auction for $500. Sunroof was leaking and the inside was disgusting. I ordered an ebay ECU with unlocked immobilizer. It should be arriving by the 27 of December. Cross my fingers is going to run.
