Gup, does that make you Hannibal or BA?? If the latter you'll need to get down to the barbers!

I love it when a plan comes together!

Could any body tell me where is terminal 50 relay? Cause when turning key, terminal 50 stays off, car won't start.

Hi all. 2006 C6 A6 3.0tdi manual.

This just happened to me. Stranded 100miles from home. Key in the ignition normally audibly disables the steering lock but nothing this time. MMI works, and obviously the door locks but no lights on dash and can’t start engine.

I have no tools with me sadly. Checked all fuses on DS end of dash. The steering wheel was free to turn though, almost as if the steering lock was never on?

First things first, where are said relays please?

Post up your engine code and gearbox type so that i look up the correct drawing for your car.

If the relay swap does not give back the instruments then you are looking at a J518 module fault as the relay coil grounds via this module.

If a J518 module fault then dig deep as the post on the net that i have seen quote over £1400 to have replaced, if you handy with tools this maybe less but a trip to Audi or a good specialist is needed for the CP removal.

Which year of car are you looking for? as they change position in the relay carrier, also the engine and gearbox codes would help to get you the correct arrangement for your car.

Have you checked the airbag fuse (Battery isolation igniter) on the battery cable for the terminal 50 supply as this may have failed.

The other relay that could cause you issues is the Terminal 75 relay as shown below.
