Default What does "Can't Synch Baud Rate" mean?

When I try to connect to the engine and immobilizer modules I get "Can't Synch Baud Rate".

Has anyone seen this before?

Default It means VAG-COM cannot determine what baud rate is needed

by the control module you're trying to talk to.

On cars made in the last 10 years, this almost never happens except when people try to use USB<->Serial converters which we neither recommend or support.

So:
* What kind of car (make/model/year/engine)?
* What kind of interface?
* USB<->Serial converters between PC and interfac?

Default This is the message

When I try to connect it just times out, and when I scan it, I get this message.

Default That's highly unusual with any of our recent interfaces.

Have you changed any settings on the Options screen?

Can you talk to the other systems in the car?
