Will Vanos timing be off

I rebuilt the double vanos unit. Before I removed it, I set number one at TDC. I did not use the special timing jig, simply lined it up the best I could visually (i.E. Both cams with rear square bolts facing up and both cam lobes facing each other, as close as I could get by eye).

I installed the rebuilt vanos unit and put in the left hand threaded bolts on both cams hand tight, then proceeded to torque the bolts. I started with the intake first (the one on the right) as I was torquing the bolt the vanos chain and sprockets turned to the left. I heard one audible click as it turned and saw the chain move. The camshafts did not move and the crankshaft also did not move only the vanos cones and pistons inside the vanos and the vanos chain and gears turned on the camshafts.

First question: Will this cause any issues with the timing of the engine (possible bent valve/piston damage) or affect the range of adjustments available to the computer for the vanos timing?

Second Question: If I need to fix this issue how do I do it and do I need the timing jig to lock the camshafts and flywheel to do this properly?

Any help would be appreciated.
