Urgent Help

Post by Evopilot » Sat Sep 08, 2018 4:55 pm

So to i removed the intake manifold on my rs4

AS you may be able to see from my old thread i had 2 knock sensor faults.... so to my horror when the intake manifold was taken off i could see the brown and black knock sensor plugs under the intake had the wires severed from the connector block...

I badly need to know the colours for each plug?? they are numbered 1-2-3 on each plug, does anybody have a wiring diagram or a link to one?

PLEASE HELP :(

So small update but little progress...

I downloaded ElsaWin V4

Managed to find the wiring diagram for my chassis number... So i need to replace 2 connector blocks, Part number 3B0973703A (Brown Knock Sensor Engine loom end) & 1J0973703B (Black Knock Sensor Engine loom end)

The problem i have is the colors of the wiring diagram do not match what i have in my hand.

For block G61 (Black Knock Sensor)
ge - Yellow
gn - Green
br/bl - Black

For block G66 (Brown Knock Sensor)
gr - Green
bl - Blue
br/bl - Black

The wires i have don't match up but are 100% for both of these sensors...
I have:
Green
Black
Yellow/Brown
(This looks like it could be a contender for G61 the Black sensor)

Blue
black
Purple
