Hi M8,
Check big relays under steering wheel.

Hi
I have problem with Audi A3 8p 2007year 2.0Tdi. Car not start, the starter does not spin and when car is igniton, electric fan started.
I unhooked driver abs,airbag,electric fan, power steering , relays and take gateway from leon, but problem is still. Has anyone an idea what could be causing this behavior? Odis shows me a whole bunch of errors associated with communication.
Here's a shot of errors :
Hi M8,

did you check fuses too ?
if the FAN starts when you crank, it must be a problem with the earth (-) check them, or jump it from the motor to the - battery with a start cable
but if the FAN starts when ignition is on, it's due to an ECU fail or a communication problem. did you check CAN resistance ? there is 2*120ohms resistors on each side, so it must be 60ohms. (you should remove your battery to test it). Or maybe some water in any control module, or defective module, that make noise on the CAN.
edit : there is no errors in your ECU, neither than N°17, did you try to jump the starter to the battery, and check if the motor start ?

Fuse and relays its ok, ecu have communication with vcds. I replace gateway and problem has still. Where is can resistance ? How check its ?
