If both are having low pressure issues, I would look at what type of fluid you are using in the tank, as I had issues some time back with my A8L W12, I was using the orange rain x, and not only did it slow down the flow, but it coated the level sensor with a film that kept the sensor from sensing fluid, so I had a constant "low washer fluid" warning, so I put some hot water in to flush the system and sensor, well it worked, but I found that I actually had the water a bit to hot, and melted the tank at a certain level, so I couldn't fill to the top, lesson learned.
Pumps are numbers 9 and 10, and the assembly is located in the passenger side front wheel well, you could try some warm water to flush, or disassemble and clean the screen/inlet on each pump.
