H&R 29176-1 are the ones you need. Always go with the vehicle specific choice.
Options listed as simply "MK5 Golf" will be a generic spring rate, rather than specific to the vehicle's weight, handling characteristics and damper tuning.
My OEM dampers were completely shot at 80K. They weren't leaking oil, but all the of the gas had gone. Press the damper rods down by hand when off the car and if they don't spring back up again, bin them.....or......if the return rate is extremely slow, and/or inconsistent across all 4, bin them.
