Unable to Reset Diagnostic Codes 850 1993

A6 2-1-4 is RPM speed sensor sporadic

Probably a loose wire or bad connection.

Your SRS light is on. The wiring to the steering wheel air bag is faulty. And the seat belt tensioner on the driver's side is faulty.

The blinking lights on your ECC are because the cabin sensors (both of them) are clogged with dust; and the recirc damper needs to be run a few times manually to speed up the flapper.

The B2 1-2-2 can never be cleared. That is the cruise control module and the code means nothing.

When the CEL flashes, that usually means multiple misfires! and could be related the to the speed sensor.
