I feel like this issue is beyond the realm of a standard mechanic
Also you do not have the tooling to make the measurements required.

Without being able to lay hands (and test equipment) on the car, I really don't think that would be much help.Do i need ot pay VCDS for some support here?
VCDS can only do what the VW diagnostics allow, beyond that you may be into getting a chip tuner to 'hack' your ECU.Do i need ot pay VCDS for some support here?
Such as? Please elaborate what measurement? Clamping current meter? If you think an oscilloscope will suffice and that I need it to get support I will. But frankly anything more than a multimeter and VCDS seems far reaching.Also you do not have the tooling to make the measurements required.

Fitting that I have one at work I can borrow! Ill need to read up on how to use it, but I have a ton of equipment at my fingertips I just need the direction where to look and how.But not just any scope. Digital Storage with 4 channels would be ideal.
I mean maybe I am wrong, but VCDS captures values within .1 of a second or so, so using the software i can pretty much graph and view signals much like an oscilloscope would.Frankly, You have no clue how wrong you are !!
Those words come from a wise man that could very likely nail the fault in your within 100 minutes.
What are you looking for or trying to find with the osci-scope?
VCDS can capture values as fast as a control module is willing to supply them. That can be anywhere between about 3 and 30 samples per second, depending on the control module in question.I mean maybe I am wrong, but VCDS captures values within .1 of a second or so, so using the software i can pretty much graph and view signals much like an oscilloscope would.

No argument. If you want to see, for example, individual pulses from a crank position sensor, or a wheel speed sensor, to make sure that there aren't any pulses missing, you absolutely need a 'scope.However it is Serial Processed Data taken within the ECU - Where as the scope will capture Raw Data where ever I choose to place my probe, some measurements are best taken at the component and not within the Module.
Using a plate-of-spaghetti diagram from SomeData? Ick!Below is a link for the electrical schematic for the ecu componentry. Help me out plz

0.7V of drop between the battery and the ECU is not something I'd consider concerning. That's due to the resistance of the fuses, wiring, and connectors between the the battery and the ECU.Checked voltages with the car running. Car charges at 14.2 volts. Fluke Meter check, at battery, jump start posts, and from junction and ECU ground are in alignment at 14.2. But VCDS shows 13.5 volts. Something is keeping proper voltage from getting to the ECU. But I cannot for the life of me determine.
Can you guys look at this electrical schematic and see any blaring items that could short out and cause me so much issue?
Apologies, but support does not have a magic wand that fixes cars remotely. [Purchasing a product from a vendor that says they'll offer support. but only provides 4 pages of ranting and ego boost. (1 page for ECU cloning actually helped)

Yes indeed and 30 samples per second is not to be laughed at ! Will 3 samples always be enough ?

further more the limitations on what data I capture are my imagination not a limited list.
VCDS & Multimeter make a great combination and will suffice most of the time, if you dont mind having to guess now and then. The addition of a good Oscilloscope and Accessories can only enhance the chances of a First Time Diagnostic Success.
I have often argued, here in this forum, that the Multimeter has no place in the modern workshop other than to measure 60 ohms across a CAN network.
You need a little more than "basic" knowledge to know how to use a meter and how it can give false positives.
