Does the ignition come on?
Yes it does, more than I would like, lol. A lot of dash lights and buzzers.OK so ignition on cluster comes to life?
Your J533 has a 20 pin connector
Pin 9 or/br > DLC 14
Pin 19 or/bl > DLC 6
Pin 1 rt/ws > SB24 Fuse
Pin 11 Br > Ground
Pin 14 > Sc7 Fuse
That is purely because you have No or Bad Communication Network - Of NO diagnostic value at this point in Time !!OK so ignition on cluster comes to life?
1. yep, and.....?Now you keep telling me have done that ?
You do realise that in that scenario only the Gateway J533 has any physical connection to the DLC Socket - Along with Pin 4&5 Ground - Pin 16 Positive ??
I not you are getting a Volt drop to 11.5v at J33. 11,5v is not ideal however if the Ground is good then the Potential Difference of 11.5v is enough for J533 to operate correctly !!
You make no mention of what you are measuring at Pin 14 - J533 - That is a question !!
Pin 9 or/br > DLC 14
Pin 19 or/bl > DLC 6 - Have you checked these wires are pinned correctly, Not Broken, not shorted, not Contaminated ?
Are you checking those Voltages with the scan tool Connected ?
Have you really either de-pinned or cut the remainder of the wires on that plug - Here we are Isolating the J533 from the rest of the car ??
Now if you cannot get communication then you have a bad J533, a bad scan tool - Bad wiring Checks - What is left ??
I know we bang / clash heads on this but my intention is 2 fold - to help, offer the best advice I have - I come with vast experience, and then learn from what I read - some very good talent here !!7. no communication still.
The FACT is that if a J533 has Power and Ground then is connected to the DLC correctly - Furthermore isolated form the car and world then it should communicate.Doubt J533 is bad, and since I have the original J533, Ive tried it as well and nothing changes. Could they both be bad.....sure but unlikely.
Noted !!scan tool is not bad, works fine on other VW's. Additionally, I have a quality scan tool I use for every vehocle except VW's and it cant communicate with anything either.
None of us are perfect - I have made some school boy errors just 10 minutes after collecting my pensionBad wiring checks, always possible, Im not perfect.
Whats left? How about bad relay?
bad J519?
Or, how about an incorrectly pinned ECu?
I don't think so on this vehicle is looks like gateway sends power and or signal out to wake up dash based on what I'm seeing from the wiring diagram. So it has merit. @hillburnsh I would be taking a close look at J519 and all of its powers and grounds as well as all relays associated with it. IS a good known J519 installed and coded to the vehicle?That is purely because you have No or Bad Communication Network - Of NO diagnostic value at this point in Time !!
Your priority / lifeline is to communicate with J533 In the car first and foremost !!
I have to keep an open mind here !!I don't think so on this vehicle is looks like gateway sends power and or signal out to wake up dash based on what I'm seeing from the wiring diagram.

that is in #7I'm stating I can communicate with the gateway (off the car/bench test) with VCDS through my breakout box with the ECU adapter.
Thank you for adding to the conversation, seriously. Just off what you just asked me, I honestly for the first time believe that between you and Dr Sheldon,, we might be able to save this car from the salvage yard.I don't think so on this vehicle is looks like gateway sends power and or signal out to wake up dash based on what I'm seeing from the wiring diagram.

Man....I wonder if i paid a lot of money and got the wrong FSM?!?!?!?!Please point out where it shows T52 connectors as I have the factory repair manual and wiring diagram and nowhere does it show t52 connectors. It is dependant on manufacturing date. Vehicle was made before november of 2010. It was made August 24 2010 to be exact
