All the usual lights come on the key light comes on and goes off so I presume it’s reading the key.

😧 hi I’m new go forums and Audi’s as well I’ve got a s3 2003 model bam 225 I bought as a project All the front end was removed and all the wiring unplugged to get ready for the engine to be removed. That’s how I bought it. I removed the engine and fitted a set of forged Conrods then reinstalled the engine wired up what I need to fire the engine It I can’t get any spark or injectors to open there’s no engine speed on diagnostic test but it’s not showing crank sensor fault. I fitted a new Bosch crank sensor but still the same there’s a plug with four bl k weed on in front of the starter motor I can’t find a home for Please can anyone help?
