C1512 ETS brake fault code

Hi guys,

After some hard braking on race track, it appears this fault code and ETS lights on for some seconds. I guess that durind this time ABS is off.
Do you have some experience with this type of problem?
Any informations will be useful.
Best regards,

C1512 w202 ets fault brake

I would clear the code and see if it comes back later.

If you are tracking the vehicle, I would recommend some harder pads AND some high temperature brake fluid. When did you flush the brake fluid? Also, when tracking you need to purge the brakes very regularly (each day) to eliminate air bubbles.

If the brake switch is faulty (cheap and quick fix) it does have some strange influences on ABS, ETS, tempomat, etc.

Thanks for answer.
After I delete, the problem appears again.
I use Ferodo Racing DS2500 pads and Motul Racing brake fluid, 660.
The whole system is properly set for racing only the ABS module and ABS command unit is stock as factory buid. So I think this is the problem and I try to find a way to trick it

Well good to hear you are using high quality pads and fluid. However, I don't see how the ABS module and command has an influence to the code I've never seen something like that

Same issue happened with my previous silver C43/C55,

our dolls uses (5-123C ESP/965) Bosch pressure sensor, which is very sensitive about fluid temp range..!,

when you use sporty/thicker oil, and start screaming,
ESP/BAS pressure sensor will detected the differ fluid viscosity, and send the H/T signal it to the ESP/ECU brains..

no worries, nothing will happen to the brake system, it's a matter of heat monitoring, and ECU want to prank you..

Its attached to the ESP/BAS pump,

but no need to replace it, it's a matter of code that stored to the ECU/ESP modules,

if you don't want that code to show up, you will have to upgrade all ESP/BAS + M/C + booster from "W220 or R230",,

i'm always doing that with any brake upgrade, but it's really not necessary if your current brakes performs well..
