Don't get the dealer to bleed the system as the machines give crap feel.

You need to do it the old skool way with two people and pump the pedal and hold it to get the air out.

We tried this as well... And didn't work

Are you leaking brake fluid anywhere ?

If not, it's 100% a brake bleeding problem.

I think I had described the brake bleeding process with the GT1.
In summary, I go to the diagnostic/testing menu of the DSC (ABS) unit and when I bleed a caliper, I open the in and out valves at least 3 times each at intervals of 60 seconds (my compressor and hence brake bleeder are not so fast).
Doing this makes a very very big difference.
It takes time, but the result is fantastic.

Thanks Alex. You have PM.

Alex, thanks for the pointer. I have sent you a PM asking for more detailed instructions but I don't know if you have received it as the sent message doesn't seem to show up in my outbox. If you can (or anyone else), please kindly send me more detailed instructions on how to bleed the brakes as I need to translate them into Chinese for the mechanics here (and I am a complete idiot when it comes to technical stuff). Thank you so much!

Hello

I understand the photo below has the GT1 menu in Greek, but I can translate.
Basically you need to connect the car to a strong battery charger and then also connect the GT1.
Do the initial diagnostics and then go to the testing menu.
Select the DSC unit and then 'activating parts'.

What you see in the far right is.
- Inlet valve front left
- Outlet valve front left
- Inlet valve front right
...
- Isolating valve DSC
- Return pump



The corner of the car that I am bleeding, while the bleeder is moving the brake fluid, I activate first the inlet valve (for 5 seconds the DSC will open it).
Then I activate the outlet valve (again 5 seconds).
I do the same thing another 4 times. In between waiting 15 secs or so.

The idea of doing the above is to let fluid pass from the DSC valves, replace the old fluid and eliminate any air.

I hope this helps.

Thanks Alex! Will have the dealer try this!
