I have a 2004 RR HSE with 83k miles. It has Check coolant level indicator as well as "Air Susp Inactive". I had coolant topped off again and the light turned off for a short drive then turned back on. Then the Air Susp Inactive warning turned on and stayed on. I'm having problems braking when I drive. And when I'm drying up hill, the vehicle seems to lose traction? Any ideas?

probably the shuttle valve in the ABS unit is defective, solution renew shuttle valve, dont let dealership sell you a new ABS unit very expensive

I had a persistent problem of hill light warning and TCS warning lights coming on for no apparent reason. There is a wire connection between the stop light switch and the control unit to let the system know when brakes are being applied. Changing the stop light switch cured it. The replaced switch was certainly sticking and the new one was of a different design. Replaced it myself as switch comes with a wiring loom. Need to get on your back under the steering wheel! Not very expensive. My car 2001 TD4

I have spent way too much money trying to get the 3 amigos to go out...ABS light, TC light and downhill descent. I have decided to try and ID the wires that go to those particular dash lights and cut them. I am tired of this ****. Landrover told me three different things that may cause this issue and told me to start with the least expensive one first! Go to hell, Landrover. I will NEVER buy another Landrover product. Which wires can I cut?

This triple threat occurs on these cars. The dealer may try to sell a whole new ABS modulator but there is a flutter valve repair that they have a TSB for.
