I have a selection of vag clocks here, some have immo off but shouldn’t, from what I can gather I have used autel and put them in service mode (I no longer have autel) I did put a set of clocks in service mode with VVDI to confirm that’s probably what I have done

I have done hex comparisment and found 5 lines of data that have been FF’ed out I was hoping to find 1 or 2 blocks that would turn the immo pulse on and off

Can anyone advise how I can get the immo to activate again please

For reference i have these tools available to me -

Chip reader for direct read / dump
VVDI 1/2 and multi prog
VCDS
X-Tools diag/key tablet with kc501
CG FC200
