Also, if trailer is plugged in, the RHS trailer brake light also doesn't work. The bulbs are all fine, and have checked the handbook and fuses, but there is nothing for RHS brake light. It is as if the RHS brake light circuit is dead! The last 3 days have become full time faults. The car will not reset and clear and the suspension remains lowered. Narrowed it down to this. The faults and suspension drop occur after I start car and let my foot off the brake peddle. Hold the brake down and suspension airs up fine and compressor turns off when bags are full. RLM Faults: U6416-86 Invalid data received from vehicle dynamics control module - signal invalid. C1A20-64 : Pressure increases too slow when filling reservoir - Signal plausibility failure. C112F-72: Air Spring valve. - Actuator is stuck open. C1130-66: Air Spring Air Supply. - Signal has too many transitions/events. Location. North Carolina. ryanjl said: Not sure what the problem is. Customers generally can't calibrate their own suspension. It's going to be "not in customer mode" while it's in calibration mode. That's a warning for the Land Rover techs to put things back to normal before they toss the keys back to the owner. Check and top up the oil level, if necessary. Start the engine. If the lamp remains illuminated, switch the engine off and contact roadside assistance or a Land Rover dealer. The Hill Descent Control (HDC) lamp illuminates continuously when the HDC system is selected and the system is controlling a steep descent. Common cause turning the key on and starting to quickly, foot on brake pedal and engaging reverse. Resolution. Switch off. Switch on and off five times completing "System check in progress"and on the sixth start then all faults should be cleared. If not then you have a hard fault and it needs attention.

Wife went shopping and when parked could not select P with the rotary selector which was jamned up in D. The D symbol was flashing and the green range light came on and off. Later a gearbox failure message came up on the display. Hello guys . I have a Vogue from 2006 and I have the same problem. When you go on the road, after 30 seconds, at speed above 90 km / h, a message "Engine system failure" appears. furthermore, it appears at the same time on the "Terrain Response System Fault" radio screen. After that, the car slows down and doesn't let me accelerate more than 80 vHnZtGF.
