2009 Audi TT 2.0TFSI bench harness

[AlanDC]

To not take this post too long, I have a salvage 2009 Audi TT 2.0tfsi and auto trans. The car does not Light the cluster with the key ON and the engine cranks but no start. I have fuel but no spark.

I need to build a bench harness to be able to read the ecm The ecm part # is 8J0 907 115 P does anybody have the schematic to build one for this ecm? Do I need anything more than the ECM to make it work?

I'm not by any means an Audi expert. Just a enthusiast trying to get it sorted out.

cluster power isnt provided by ecm

On the ECU there should be a 4 digit engine code for that specific car, something like CCZA or CETA. You can find the component pinout for that engine code on erWin.

The cluster is lit from the BCM, without communications to the cluster on those earlier MQB cars, the car cuts spark and triggers the immobilizer.

Thanks all for the answers. It turned to be a bad gateway module. Is the one below the cluster. On the right side where the driver legs are.
