If no air has got in the system I understand can bleed as normal. Only if air has got in do you need electronic aids. I'd put a months pay linkages not done then.
I've heard this also and is probably correct, but............ Don't think it's Speed III specific but I've also heard you can get corrosion in the ABS unit if the brake fluid is not flushed through every few years. Brake fluid is hydroscopic so I guess it's a possibility, having to replace an ABS unit is not a pleasant thought.
Very unlikely there will be issues with ABS control module due to lack of fluid changes. The main safety reason for renewing fluid is because of the risk of brake failure if water content in fluid too high. Water will boil, leaving a void in lever/ pedal pressure. Fluid moisture content can be measured using a simple/ cheap moisture tester. If tester comes back with readings within tolerance I would not bother changing, however if readings outside recommendation then defo renew
