[s-cars] Resetting the ECU

[Jared Robinson]

So, my car is only making 1bar. Hoppen believes that the Lehmann chips I
have should be making 1.3 bar, but he's not 100%
he asked if I have any codes, and I do. A few months ago I got a knock
sensor code on an extremely hot and muggy day. it hasn't happened since and
the CEL is off.
I was told to reset the ECU of codes, but I don't know how. They told me
only a VAGCOM can reset it.
I don't know anyone who has a VAGCOM with the 2x2 locally (aside from Tom,
but he's done so much for me already and I don't want to bother him
everytime I need something)

Is there any other way of resetting the codes on the ECU?
