[josh@jlttech]

Good day, could someone offer me some assistance. i have a golf 7 Gti that we replaced the ecu of and after taking out the cluster to extract the immo data from the cluster, it wont turn on the cluster at all now only when you open the door.

Looks like absolutely nothing is powered on except the Gateway.

I wouldn't expect that to happen even if the cluster was dead...?

Got a wiring diagram?

Hi, yes the basics of it i should say buy no power to the terminal 15 voltage supply relay and when we give it power it brings up "Starter System Faulty. Workshop!"

You f*cked the Cluster by extract Immo Data.

 

[Derek]

when we give it power it brings up "Starter System Faulty. Workshop!"

If you run a scan with it powered up, do the other modules show up?
Best regards
Derek

cluster still comes on when you open doors and that, so i highly doubt that, we have found tampering with wires from the previous people who worked on the car. However thats also the only way to extract immo data for the MQB keys.

thanks Derek for this, I've also thought of doing this just haven't had the chance yet but im going to give it a try shortly.

flllow fuses, cables for Kl15 , nobody know what exactly you did
if you do ECU swap , you must know little bit more than kinds from High school , so start use your brain

maybe not, but I love people who think ECU is like a...hmm...bulb..... tur out, turn in...bingo
Africa enginners comming ...... from stone edge to Component protection, Immo, OTP within a minute

none the less the ECU is coded correctly however we did find that the main relay inside wasn't getting power, and came to the conclusion after looking at diagrams and found that its the power supply control module. Is the power supply control module incorperated into the BCM on these cars?

 

[Uwe]

its the power supply control module. Is the power supply control module incorperated into the BCM on these cars?

What's the component identifier for that module on the diagram?

-Uwe-

 

[josh@jlttech]

-Uwe-

After checking some wires its the BCM that is responsible for the power supply to the control units.
