Computer codes? 1111--Ned's comments

[Phil Payne]

> In a no start condition you have to crank the engine for at least 5
seconds before pulling any codes.

> Since the engine doesn't crank over there are lots of sensors that have
not received a signal.

> Reference pin on the flywheel
Engine speed sensor on the flywheel
Hall unit in the distributor

Only the rpm sensor should fail in this situation - 2111 and only 2111 can safely be ignored.

> If I was the computer I'd give a 1111 too.

No.  "1111" is exclusively internally derived (at least in the MAC12D and MAC14 code) although
it's possible some marginal conditions could be caused by low battery voltage.

> Just because a starter goes klunk does not indicate that the solenoid
has made an electrical connection to turn the starter over.

Very true.  On some Audis, the connection between the N/O solenoid post and the field coils is
a copper braid that passes between the solenoid and the motor casing with no protection - if
this goes intermittent you can get problems.

> REPLACE starter with probably defective contact in the solenoid.

A junkyard starter is a good test.  If it works, it's your choice whether to keep it or go for
a new/reconditioned one.
