ECU Pins

Does anybody know what the T17r (white) wire connects to, or what function it does in the ECU, if anyone can help I might be able to get some money back from a recent repair.

The car is a 2010 Audi A5 with a 3.0 turbo diesel (8T).

Thanks

Here is the repair order that diagnosed the pin fault.
Vehicle will intermittently not start and run, vehicle will crank and fire once but will then
stall and throw transmission and engine code messages onto the drivers Instrument
screen. This only happens when the fault occurs though and it does not occur all of the
time, it’s a very intermittent fault but when it does occur the vehicle will not start and there
are then miscommunication fault codes for the CAN BUS system logged.
---------------------------------------------------------------------------------------------Checked engine
cutting out / not starting.
Checked fault codes. Multiple faults logged for no CAN communication.
Carried out a wiggle test of various harnesses and connectors throughout the vehicle.
Was able to induce a fault into car when wiggling harness in ECU box.
Narrowed fault down to the ECU wires in connector T17r (white ) in ECU box.
Replaced CAN high and low pin in connector.
Tested. All OK.
Cleared fault codes.
Carried out extend road test - could not get car to re-fault all ok.

Sure, how do we divide the profit?

/1 to accelerator pedal T6/1
/2 to accelerator pedal T6/2
/3 to accelerator pedal T6/3
/4 to accelerator pedal T6/4
/5 to accelerator pedal T6/5
/6 to accelerator pedal T6/6
/7 ABS to power steering
/8 connects ECU to brake pedal switch
/9 BCM to oil pressure switch OR ABS to power steering
/10 BCM to aircon pressure valve
/11 LIN bus
/12 BCM to aircon pressure valve
/13 can PT low <---- INTERESTING
/14 can PT high <---- INTERESTING
/15 terminal 15
/16 connects fuel pump relay to anc. fuel pump
/17 connects ECU to convenience module

Hmm, not what I was hoping for but I will still proceed with the request for a refund

This is hardly enough documentation for such a request.

It would help to have an auto-scan posted before said repair and after & to show it is the same condition, then take back to have them make it right or seek reimbursement.

How do you know it isn't a different problem or a vicarious result?

What was the cause and need for repair?

There is a product called stabalant 22 which I have used and don't know the opinions of some of the major contributors to this forum have on it's use. Was told in some VW Audi circles is actually required, again cannot validate this maybe Jack could embellish on it, but is not dielectric grease.

It is fairly expensive and in many cases makes contact in electrical connections where you had issues before. It would be worth a try, also would like some feed back here for opinions on this product of major contributors to this forum.

Is supposedly bridges micro fishers which come over time with connections.

In fairness to your mechanic connections can be a struggle and replacing connectors very troublesome, also might have a fracture in the wiring which acts like a wiggle test at the connector but may be farther up the bundle.

Phelmer, glad you clarified, the "Eh", I always thought it was 'A" as I ride with several Canadians in the BC area, great bunch.

Also to clarify, there is have been told, Stabalant and Stbalant A, or maybe they meant Stabalant EH, which has or can have Alcohol added when evaporates, not sure which is which though.

Stuff is almost like snake oil, don't know but keep ours in refrigerator, again maybe a misnomer just what I have been told, and at the price keep it away from the general users in the shop.

Sure why not...... I put Torque Seal "anti sabotage inspectors lacquer" in the fridge.

My favorite now is UV invisible type for later!

This guy could benefit from such habits...........

Jack, I'm clueless here. Is this something like super glue which also benefits from refrigeration, not familiar with this product, could you embellish?

This is not glue, it is what a tech uses after he toques a fastener as quality procedure & what a Federal Aviation or IA/AP inspector uses to determine if someone has tampered with a component or to detect fraud/negligence.

You will find that auto makers do this too...........such as for example on throttle switches etc.

Got it, I suppose I would use yellow paint stick here.
