VCDS Serial number

2014 Audi A4 Avant 2.0L 177BHP - Engine light came up few days ago with flashing glow plug light and traction control error, been attempting to diagnose the issue since, replaced the crank sensor already as was told by someone else its likely this, purchased VCDS but doesn't really seem to shed much light on the issue is there anything else I can do to try track down if a sensor is out on the 5v circuit or if its a wiring issue via VCDS? I can't even find which sensors are on the 5v circuit that it mentions.

I assume you've been here?

You're going to need a wiring diagram for your particular car/engine.

"Open Circuit" strikes me as most likely to be a wiring or connector fault. I believe the ECU monitors current being pulled from its 5V reference output(s) and would flag the fault that way if the current is zero.

In addition to his eminence's fine suggestion......

OP

Did you try unplugging the engine bay side connector and further measuring the 5 volt + voltage directly available at module output current tracks yet and does the aforementioned fault clear with only the one side plugged in and key on via scanner?

Engine bay side connector you mean the two connectors which go to the ECU? I've just purchased the wiring diagrams to find which sensors are on this circuit and their pinouts

Indeed my caps lock key was stuck!
Time for a keyboard!

Yes the connectors at ECU, however, the one going to engine consumers should be unplugged to isolate if problem exists at ECU directly or forward to harness to engine sensors and load devices.

So I've used the wiring diagram thanks for the links and tested the five sensors on that circuit, and they all read 1.8volt instead of what I believe should be 5v. I've found the source of the power pin 25 on the ECU and its also 1.8volt there. I have no idea where the ECU gets the 5 volts from, but I'm guessing this is a good indication that the ECU is at fault here?

Hello,

Did you check whether there is any sensor which may be pulling the 5V ref circuit to 1.8v. Please you must also check your powers and grounds to the ECU before you blame it.

Hello yes each sensor was tested off the circuit to make sure one wasnt bringing the circuit down to 1.8. Going to check grounds and powers next!

Fixed the issue, wiring chaffed.
