I would like to retrofit AAC to my MY2017 X260.

From what I found I will need:

Radar unit
Radar mounting bracket
Grill for cars with ACC
Steering wheel right button panel with distance buttons.
CCF modification

Someone mentioned a different ABS unit, but my car is equipped with AEB, so it can brake automatically already (?)...

Am I missing something?

Hi Tom, you can't use it down to '0' as it turns off at about 25MPH, unless you get someone to edit the cars CCF (car configuration file) via SDD on the X250.

This is the x260 group. And that will go to 0 and can have queue assist too so it will creep you forward in traffic.

Yes, with Queue Assist the ACC will bring the car to a halt automatically when the lead car stops, then to move off a gentle tap of the throttle will make the car follow the vehicle in front.

is it working now?

I have one question on the ACC function. Can it be used in traffic jam? Does the car brake to 0 km/h and starts moving when the front car moves?
Is it worth doing all the retrofit incl. change the ABS unit?

it works in traffic jam but you can activate acc above around 20km/h. once activated will work till car is moving - even 1km/h - and it's really try to not stop the car. if you're in the jam that require full stop whole the time it's not too much comfortable, at least i'm not finding it as such. you have totuch the gas to run the car once the fron one will start driving. so on highway jams it's nice future, but not city onces i would say.

I've been approached by a company to do this on my R-S at cost.

It took Onotole about 3.5 seconds to do on mine, BUT.. you need ACC in the first place for it to work.. How would they make ACC work on your XFR-S?

And tbh, you also need sphericals of steel to trust it, it's very 'flaky' on the X250, meaning that that you very often have your foot hovering over the brake pedal because the distances it keeps aren't consistent, therefore not 'comfortable'...

Just my experience, others may feel different about it on the X250...

At cost meaning the cost of the modules and the new steering wheel button. They never had it as an option on the R-S, but it would just need the radar module as the wiring is there.

It's worth noting that this is only possible on the second phase of the facelift i.e. the 8-speed.

Little update guys, Onotole working round the clock trying to fix mine

When the B abs module is installed, car flashes up multiple errors. Those include yellow ABS fault, stability control fault, ASPC unavailable, forward alert unavailable and a few others. The codes in the DTC are a U3000-55 in the ABS module, and IPMA has a U0001-81 fault. Abs module correctly flashed. CCM correctly flashed. Just a bit confused as to what can cause this now.

Anyone with suggestions welcome

Are there any news?
Did you (or Onotole) fix the fault?
I am still collecting my party for the ACC retrofit and want to start in the next few month.
Did you install a new wire to the ACC sensor or did you just use the preinstalled connector?

The connector for the ACC module is preinstaled, but the 12V wire is not connected on some early 2016 cars. You can check it by switching the ignition and measuring the voltage on the connector pins. There should be 12V on two pins (on one side of the connector).

thanks PGG.
I have 5 cables in my preinstalled connector so it is with B+ and ignition.

I have 2 more questions to the installation:
ACC Radar:
Do I need to calibrate it? The radar is installed with ballhead screw on brackets which are adjustable. I would try to install the radar as horizontale as possible. But is any software for adjusting needed?

Steeringwheel switch:
How can i install the switch? Do i need to remove the airbag or can i just remove the (chrom) sourounding of the steering wheel?

Can anyone help?

The airbag has to be removed to access the steering wheel switches.

Hey Guys,
i give a little write up of my current status of retrotfitting ACC.

Basic:
F-Pace MY2017

Part List:
ABS Modul GX7314F446BF
ACC Sensor GX739G768AD
Radar bracket HK839E729AD
Steering switch GX7313D767CD
Grill HK83018K28AA
Badge for grill FW9316B856BB

My Jag is at the painter's from today for repaint the front Bumper.
So the ACC and the new grill will be reinstalled instead the OEM version.

In the next 2 weeks, i will change the ABS Modul from "A" to "B".
The steering switch will be changed too.

Then comes the funniest part of doing the SDD Config

One short question for my Timeplan...
How long does it take to change the abs module?
I have support from 2 mechanics and their tools.

2 hours? Or longer?

cause of the new abs block i want to change the brake fluid.

What kind of brake fluid do we need for our F-Pace?
and how much liter do we need?
