You can't map it out with VCDS - that can only change the coding whereas to permanently remove it the ECU needs to be flashed with new code, the same as a traditional remap.

It can be DIY'ed using Nefmoto software and a generic OBDII to USB cable, but that does carry some risk as it has the potential to brick the ECU if it doesn't work or goes wrong.

The easiest solution is to just fix the vacuum pipes to the solenoid and the two SAI valves so the system works again. There's not really any advantage to mapping it out when you still have all the hardware in place and don't plan to remove it. Its more the remap allows the hardware to all go away.

Thanks Michaela. Do you have a photo of the vacuum pipes so that I can locate them and fix the problem?

Vacuum line schematics are in the engine service manuals in the thread linked below. I've used them myself to rebuild mine. A roll of vacuum hose is £15ish on eBay
