Not sure if it was brakes or CC gearbox but Emblem told me there is a bleeding system built into the software that runs a pre-programmed process.

Are you using a pressure bleeder?
It’s longest pipe to shortest (whether this makes a difference these days is debatable) so given the ABS pump is in the front left corner it will be right rear, left rear, right front, left front.

The general recommendation is that you start with the wheel furthest away from the master cylinder and finish with the closest, but it doesn't make that much difference.
A pressure bleader (gunson) helps but we use a vacuum pump on the calliper end;
They help as they come with a tube setup that allows you to pull fluid out of both sides of the calliper at the same time.

The reason I wanted to check..As mentioned it isnr perhaps crucial with a pressure bleed set-up but the point is, is it the ABS pump ( Ive never worked on and abs system before) or the master/booster, because they are opposite sides of the car !!?
And because I wasnt certain how much/little pressure I could get away with past the ABS block....

I think there is an option in multiECUscan (Fiat group diag software) where you can cycle the ABS pump whilst bleeding the brakes but it's not necessary. Just bleed them as you would any other car. The only difficulty I've had in the past has been with the 4 piston calipers and have 2 bleed nipples, 1 either side of the caliper. But bleeding both both at the same time helps.
I think this is probably the right answer...
The ABS module is likely a bottle neck for trapping air in all it's nooks and crannies from what Ive read....but of course, the pump to ABS block must be air free first and foremost...!
On a 4200, it means rear left, rear right, front left, front right...to be pedantic ! Luckily, with a pressure bleeder it hasnt made any difference.
I have to say , (and Ive got Brembo monobloc and other type calipers on several bikes that I have refurbished a number of times) I cannot believe how much cranking up the bleed nipples take to stem that annoying weep that they seem to do. Ive never needed to apply so much torque to a bleeder before. I started by cussing the tech that rebuilt all the brake lines recently but soon disovered that "yes"...it seems you do need to tighten them up that much !
