Dash oddities

[JohnMatrix]

Hi Folks,

hoping you might be able to give your thoughts on this oddity going on in my VZ Berlina,

I can't remember when this started doesn't affect the car starting, and seems to go away when ignition on, I have another issue where randomly when driving the dash will reset itself it seems , fuel tacho gauges reset and then come back, car does it's system check comes back OK, engine stays running,

Have put brand new Battery in car, and it hasn't done the dash reset again touch wood, only the flashing odometer remains at this stage.

Have scan tool 2 codes seem to repeat after clearing them often,

Occasionally when scanning after engine start received
P1668 Alternator L Terminal Circuit Malfunction

and DTC 18 Auxiliary (Secondary and Tertiary) Serial Data Bus
Fault

would love to hear your thoughts cheers.

possible abs module
possible alternator

Cheers Lout, not sure how extensive supercheap's tests are but had the battery and alternator tested seemed to be fine now with the new battery, and my scan tool has the car at 14.3v so it seems the alternator is working ok, have been searching about the ABS is there any diagnostics you might suggest?,

just unplug the electrical plug to abs module and see if fault reoccurs

Hi, just wondering if you resolved this problem? I have the exact same problem and have struggled with it for years
