By "Engine Start" do you mean pressing the Start button?
The security light does keep flashing after the car is unlocked, and after the key is docked - this is normal. It doesn't stop flashing until the Start button is pressed.
Getting this far suggests to me that the security check has been successfully passed. Ignoring the HDC fault for the moment this is basically reporting two things - that the bonnet is open and that the clutch is not pressed. Both could be significant - if the clutch is not fully pressed then the starter will not operate, which would seem to match your non-start symptoms. So the first thing to check is the clutch sensor - if this is not working properly and the clutch is not being detected as pressed then the car won't start. Secondly if the bonnet is open the car won't lock (see next point).
The horn sounding when you lock the car isn't normal - it means that a door or the bonnet is not closed properly and in that case the car doesn't lock. The horn is telling you that it hasn't locked because something is open - the FL2 is silent when it locks properly, just flashing the indicator lights to confirn the lock. Given the bonnet message above that's the obvious place to start - again check that the bonnet is properly closed (both latches - one each side) and that the bonnet closed sensor is working.
It sounds like something much simpler that that to me. The fact that the engine starts and runs if you hot-wire the starer suggests to me that everything is basically working as it should, and the Press Clutch message suggests that is may simply be that the clutch isn't being detected as pressed, |

Hi Pab!
-- Yes, pressing the start button. When i do this, it engages "System Check", performs its checks on instrument cluster but still does not start - Then says (i think) HDC System not available or HDC system Fault
-- Once Key is docked, red LED light keeps flashing, even when i press the start button (Gear in Neutral, Clutch down) - Then performs system check (Does this mean the start button is working/fully functional/doesnt need recoding of some sort?
--I will need to check this - as it hasnt been checked - clutch now sits on the floor and doesnt come back up - mechanic said i need to bleed the system, if clutch is all the way down already, gear in neutral - it should start? Is the clutch sensor difficult to reach or? Might be worthwhile checking the neutral gear sensor as well? -- also, the steering lock i see is hanging from its cable that leads into internal electronic systems (attached and connected) - will this need to be attached to steering wheel column to function?
-- I agree, even with bonnet closed, all doors closed, windows all up - the horn goes off once every time i try to lock, but never actually locks anything. --because it always says bonnet open all the time, i assume a faulty bonnet sensor - but this shouldn't cause the starting issue?
-- You could be right, i will have them check this out tommorrow Below are a few other considerations i have put together with my research so far coupled with aspects from different places. 1. Suspect Coding on KEY/FOB -Checked twice by Direct Data(Auto Diagnostics shop), they said the FOB is working fine (but would not give me details as to how they actually checked this) 2. Battery Problems (Low Voltage, Dead Battery) - Replaced with Manufacturer spec 658 Willard brand new battery 3. Fuses and Relays - Had auto electrician come out to test and check all relays, fuses etc - all looks fine 4. Steering Column Lock - Is hanging from its connected cable into the dash (assume, still connected) 5. Radio not Shutting Down properly - Would cause battery to lose power (this is not the case having connected brand new battery) 6. Bluetooth Headset - Mine doesnt have this, nor satnav 7. Manual ECU Reset (remove battery, leave for 10 mins and then touch both + & - terminals together - Did this a few times, no difference. 8. Fuel Pump - 9. NO Voltage at Glow plugs (AT ALL) through multitude of tests, glow plugs are not receiving any power at all (Tested with Digital Multimeter whilst pressing start button) 10. Faulty Starter - If starter is connected direct to battery, car will crank and start if using engine start spray 11. Ground Cable connected from - terminal to the body - Will need to test this somehow, although im sure i wouldnt have any electornics working at all if there was a ground short? 12. Immobiliser (BCU) - no idea what, where or how to test this>. [/b][/quote] |

I believe that's a simple problem of authorization.

Thanks Alex, not sure where in the world you are - but here in South Africa, Land Rover plays themselves like GODS with the prices they charge hence avoiding them as far as i can - also, the earliest booking i can get is +2 weeks away. I will keep the forum updated as we go along. as per above from User PAB, i will try and have the current place that is looking at the car do the following first checks before moving on.
