Unfortunately, I am not able to provide any reference from the manufacturer on this. However, recommendations usually point to a certain range, which is between 20 to 40 psi, rather than a unique figure for TDI/TSI engines of VAG cars.

Normal running pressure range in an R134A system is in between 22, and 57 psi with respect to below reference, https://sciencing.com/normal-running-pressures-r134a-8003413.html Below video also provides some tips, and safety precautions for filling up the gas individually, https://www.carcarekiosk.com/video/2011_Skoda_Octavia_TDI_CR_2.0L_4_Cyl._Turbo_Diesel/air_conditioner/recharge_freon

Any portable steam generator / cleaner with vacuuming ability helps. For ease of cleaning, and protection, I chose to use leatheratte seat covers, https://photos.google.com/share/AF1QipPDer_oWqKiqZvr3JvH0vVG3YEtsOoJ76_1CyfTdt8kuyEFjJSttqEeTes-xd3Utw?key=R0JHQ3FKX0VhZXM2b09Wd25YRklBS21oejU1eVhR
