Wow, you sure do have a long shopping list.

Lets start with the the basics and more important issues.

You mentioned the ignition switch is staying engaged, do you mean the starter is not returning after cranking?
Did you replace the switch? Is it OEM or after market?

Is the engine oil and coolant level correct? Just want to make sure it is a false reading due to electrical faults and not a fault with the engine.

Have you tried to check for trouble codes?Most part stores provides free scanning services but yours is pre-OBD-II so they might not be able to help.

Yes the ignition switch was replaced, unfortunately it wasn't installed correctly and burnt up the starter. You have to turn the key back so that the starter doesn't stay engaged. I don't have $300 to have it re-installed, and yes it's OEM from AUDI. Engine oil and coolant levels are correct. Having a hard time finding an OBD-I scanner.

It could be a fault with the ignition lock cylinder.

Did you perform the replcement yourself?

You can use the manual method of code retrieval.

Sorry, my bad. There are no manual method avilable for this model.

Most code readers would not read pre-OBD-II vehicle but most scan tools can do that as they are equipped with the necessary program and connectors. Parts stores would not be able to help you on this so you need to check with repair shops or the dealer.
