Problems are what the title says.
Passed Uk Mot test yesterday although the Lambda struggled to get into the Green zone for a while.
Ran fine on the way home and this morning began to misfire from cold.
On Parking the Red Steering Wheel light came on and no power steering assistance at all. Engine MIL on.

Turned it off, Dug out the VCDS and started the car again. Power steering working no misfire MVBs for the engine all in the Green.
J500 Intermittent Fault showing.

The 09 Interior lights and 56 Radio faults are known issues that I can't do anything about till my hand works again

Car has been standing for about 4 months due to lockdown and a hand operation. I'm hoping corrosion on a plug somewhere.
If the steering Rack had died it would stay dead??
I do realise that these are likely to be two different issues.
Any thoughts, opinions or previous experience would be gratefully received
Thanks, Graham

I think you've got some electrical issues there.
- It looks like the steering rack was off-line for a bit.
- The Fuel Pressure Sensor -- Short to GND code.

Both of these could have a common cause, such as a common +12V supply.

Given the age of the car, the first thing I would do is pull, inspect, and then re-seat every fuse. Or get a wiring diagram and see where the steering rack and the fuel pressure sensor get power from and look for something they have in common.

Thanks Uwe. Sounds like a sensible way forward. Back to the joy of Audi Wiring diagrams

I had an a3 some years back that would randomly misfire with low fuel pressure, we finally traced it down to the screen on the in tank fuel pump which randomly clogged depending on fuel level. VW actually were aware of the issue and modified the pump which solved the issue

The loss of power steering can be caused by low battery which if it’s been standing for 4 months may explain that, I’ve just replaced a battery on one in the last week with the same issue
