So, I reached out to Volvo UK and they came back with the following info.
Option 99811 is:
- heavy duty battery (760CCA, 70AH)
- 180A heavy duty alternator (standard specification D5 has 150A alternator)
- Police 17” wheels
- 17.5” front brakes with front brake wear warning system (these are the biggest front brakes from the XC90 model range)
- full size Police spare wheel & tyre
- tyre sealant kit
-Jack and wheel brace
-warning triangle
- tunnel console blanking plate (where the cup holder fits). A spare cup holder assembly is supplied to replace blanking plate when car is decommissioned and sold on.
- 2 X rear fog lights
- steel safety dog cage in load compartment
- Day Running lights turned off (Software is required to turn them back on at a cost to customer)
- unique Police upholstery (hard wearing)

Option 998195 is:
- Emergency Specification Supplementary Manual
- additional Police wiring with communication ports and connectors to allow fitting of Police equipment
- Emergency Service Equipment Mounting Bracket (for mounting of Police radio equipment in the dash area)
- Observer’s 3rd mirror (fitted on top of LH/front door mirror assembly)
RA04 Police Chassis is:
- Police specification front shock absorbers
- Police specification front coil springs
- Police specification front anti-roll bar
- Police specification Nivomat self-levelling rear shock absorbers
- Police specification rear coil springs

- Reinforcement brackets fitted to rear suspension lower stay arms
Above is designed to give optimum high speed stability and handling with heavy loads which these Police specification models are subjected to.
260G Engine Optimisation Aftermarket – Engine calibration Police is a standard Polestar software upgrade to allow more power / torque on D5 Police engines. It takes standard D5 engine 205 PS / 420 Nm up to 235 PS / 470 Nm as these Police cars require more performance for high speed driving. The engine upgrade is performed in production build by putting software upgrade in ECM.
Now I know and based on the above, will make my insurers aware
Shame that the Police didn't pass on the cup-holder or spare wheel/jack/various other bits but also handy to find out that the car is already Polestar'd and together with the other upgrades is why it handles reasonably well.
