95 Passat VR6 DTC erase?
 

I'd like to erase the DTC codes on my 95 Passat VR6 (OBDI).

Right now when I check for codes (ignition on, jump 4-15 for 3 secs,
repeat) it has codes 1344 (secondary air), and the one for the impluse
sensor.

I try to erase all codes by connecting the two pins then turning the
ignition on and disconnecting after 5 seconds, but then I get all kinds
of other codes beginning with four. After a while cycling through
these I get a clicking and then on the next code some pump starting up,
at which point I turn the ignition off before something irreversible
happens.

I got the erase procedure from the Bentley for VR6 in the Golf and
Jetta. Is the Passat any different?

Thanks,

Guido

You need to fix the issue first, otherwise the MIL will come back on in a
few days. Or if you fix the issue and it doesn't happen again the MIL will
go out in a few days.

The MIL light was intermittent, but it has stayed off for the past few
days since I changed the impulse sensor ($50). The DTC memory still
shows the code though. I don't know how long it remembers everything
that ever went wrong so I don't want to be chasing an old fault that no
longer exists. I'd like to delete all the faults from memory and start
over. Is there any way to do that?
