I've often wondered with this, how you can tell whether it's already been done. What's the mileage on the car?

In Dev mode, you need to find actuation's in the braking system, you can just set it back to 0. With the error you have it is actuation's and not time to pressure. If the error is for time to pressure then you need the pump to be fixed.

WARNING!
If this does not make sense to you then I would recommend not attempting it as you can royally screw up your car.

Try this:

Make sure engine is running!

In Developer mode you need to go to Entwickelingsdaten - > ansteueringen -> Gesamstliste aller Ansteuerungen

to see how many times brake has been pressed there is a line that says: Bremsenzahler (DJ_GetBrLive)

then 1 line down there you see Bremsenzahler aktualisieren und Lebensdauerzahler F neu berechenen -> click it !
Parameter uINBR = 0
then click F3

1 line down Bremsenzahler auf beliebigen Wert setzen (DJ_SetNBr) -> click it
Parameter uINBR = 0
then click F3

then scroll down untill you see the line's :

Lebensdauerzahler F neu berechenen (DJ_CalcLiveTime)
Parameter uINBR = 0
then click F3

Lebensdauerzahler F neu berechenen und schreiben (DJ_BuildAndWriteF)
Parameter uINBR = 0
then click F3

Log out of SBC !!
log out of verhicle !!

let engine run at least 10 minutes or drive at least 10 minutes

If no coils are damaged , SBC fault code is not AKTUEL no more

RESET SBC SERVICE LIGHT:

Engine is running.

In SD Developer mode you need to go to:
Entwickelingsdaten (developer data) ---> ansteueringen (control gear) ---> Gesamstliste aller Ansteuerungen (complete list of all the control circuits).

To see how many times brake has been pressed there is a line that says: Bremsenzahler (DJ_GetBrLive) (brake payer (dj_getbrlive)).

Then 1 line down there you see:
Bremsenzahler aktualisieren und Lebensdauerzahler F neu berechenen (brake upgrade and lifetime payer payers recalculated f) -> click it.

Parameter uINBR = 0 then click F3.

1 line down you see (or search for this line):
Bremsenzahler auf beliebigen Wert setzen (DJ_SetNBr) -> click it.

Parameter uINBR = 0 then click F3 then scroll down until you see the line's: Lebensdauerzahler F neu berechenen (DJ_CalcLiveTime).
Parameter uINBR = 0 then click F3.

Lebensdauerzahler F neu berechenen und schreiben (DJ_BuildAndWriteF).
Parameter uINBR = 0 then click F3.

Log out of SBC. Log out of vehicle. Let engine run at least 10 minutes.

Reset is only a temp fix to alloy you extra time for proper fix but should never rely on it as a permanent due to the brushes ware and the pressure cylinder or whatever its called possibly be at the end of their use

When the brushes or pump start to show signs of wear the system picks up that it is taking too long to reach the correct pressure and will warn you of such.

If it is just the number of cycles counter then it will allow you to reset it and carry on as normal, as the pump is working fine.

The system is self-testing and will warn you when it is struggling to keep up. Then it is time for a new pump.
