Really, that's interesting! I'm not sure it was ever clear exactly what one had to do, just that there might be a coding way to resolve it.
Can you share exactly what it is that you did? Settings before and settings now?

Also, do you have active cruise control by any chance?

Interesting results. What were your settings before the changes - really need to know that for reference - as there appears to be no similarity between cars fitted with the same system, unless ACC has an impact.

While mine is still spongy, since I had the front discs and pads replaced under warranty it is better.......

Do you have adaptive cruise?

That's my latest theory for spongy brakes... Cars with this are set up with soft initial bite to help the system to modulate the braking.... Thoughts?

SkyJawa · 10-29-2015, 04:44 AM

Yes mate I do, its certainly a possibility though I'm not sure theres any difference in feel when its on or off so would likely be all the time regardless of cruise active.........

ACC also has FCW so maybe that has an element where it starts braking for you and firms up the pedal for you to slam your foot on it.

Only way to tell would be seeing the coding of a few ACC car, standard cars and Safety Pack with no ACC cars (IIRC that has the FCW in the package?).......

I cant say that mine feel soft but then again I've not driven another car with MS brakes. I always found them to be very responsive with a good level of bite.

I have no issue with my cars stopping power so I'm not sure I want to try setting them to aftermarket!

If you look at the attached I don't have these options. C_Variante_Bremsscheibe_vorne_e (Front Brake Disc) has no valid values to choose from.
C_Variante_Bremsscheibe_hinten_e (Rear Brake Disc) does have different values to select but none are in mm.

The values may change of course once you VA code the aftermarket performance brakes.

Hi I have exactly the same situation as you. Have you ever figured out why is this different from the other ppl's posting? Mine front rotor size also not changeable, and don't even have rear rotor size selection as below. Anyone could help or have any idea why? Thank you

I believe that means you don't have correct pszdata for the i-level installed in your car. Get the latest pszdata and check again.

Question: Why is it necessary to manually change rotor size after adding SPBR and VO coding DSC? I would have expected VO coding to include new rotor size.

I thought it would, but some say yes and some say no....

I have updated to the latest pszdata and esys and still no rotor size options. I guess there are two different sets of the DSC contents as i have seen others who doesn't have these options, too. Quite weird....

Can you fix this problem. If you say yes; how to?

Regards.

graphys · 05-02-2017, 04:09 PM

Can any one fix this problem? Added SPBR but not change anything.

Please help this issue.

Hey guys. Anyone can fix this issue? Please answer.

My values I attached here:

Did you ever get this solve.. I code my brake and have the same value as your.. Any help is greatly appreciated

Great thread resurrection. This could be useful to others.

It was only yesterday that when slowly manouvering I noticed the brakes felt crap, like 40% of the servo assistance dissapeared.
Normal driving outside the car park, felt fine.

I wonder if it's related to what's been discussed here.
