Hi John, all doing well mate.

I'll be honest and although it can be changed there will be some trial and error as I've not discovered what the T values are that can't be altered at they're fixed within the modules firmware.

Here's what the manual says...
Quote:
HWS adaption:
Channel 6,HWS activation delay time / HWS pump activation times, value 0...255, range 0 - 2.55 sec
Channel 7,T3 / T12, value 0...255, range 0 - 2.55 sec
Channel 8,T4 / T13, value 0...255, range 0 - 2.55 sec
Channel 9,T7 / T16, value 0...255, range 0 - 2.55 sec

The times T5, T6, T10, T14 and T15 cannot be changed by way of adaption. The time T9 = T18 is calculated from T9 = (T2 + T6 + T8) - (T3+ T4 + T5 + T7)

If T9 < 0, then T8 = T8 - T9 and T9 = 0.

Otherwise the pump and nozzle run asynchronously!

HWS pop-up washer jet motor activation times:

Channel 10,T2 / T11, vaule 0...255, range 0 - 5.1 sec
Channel 11,T8 / T17, value 0...255, range 0 - 5.1 sec
Nice and easy so far

Login to module 4F, Security Access 12151, Do It, then change the values in adaption channels 6 - 11.

Just for reference here are some values (6-11)
100;40;100;70;75;100 from my A8
100;40;60;100;75;100 Factory Settings
