Question about 2004 Land Rover Range Rover

2 Answers

I have a 2004 Range Rover HSE. It all started a few months ago when the key wouldnt turn in the ignition to start it. I had it towed and then the key would turn but the car would not do anything. Now its driveable sometimes but you cant trust it because every 3 or 4 starts it wont start unless you play with it for a while. I have to unhook the battery ends for a few mins then hook them back up and wiggle the steering wheel until it will start. It only has 42000 miles on it. It also says coolant low and air suspension inactive. It is full of coolant! PLEASE HELP!!

I have had the same issues with the ignition switch, you can replace the switch, but in my case the solution was actually a new battery. The early L322 Range Rovers have a very high power drain with the vehicle turned off. I have never found a good solution for this except for a main battery cut-off which is not a good idea due to computer issues. If you have periods of time when you do not drive for over 2 weeks a cut-off would be worthwhile.
Load test your battery, and replace if necessary. A number of warning lights can come on when the battery is disconnected (or very low in charge), with a good battery they usually will go off after the vehicle is driven for about 100 yards.

    I have a 2004 Range Rover HSE and had the same issues with the ignition switch not turning. In my case, I needed replacement battery and everything was fine. Shortly afterwards, maybe 6 months later, I travelled for the weekend and upon return car would not start battery dead. I boosted battery and everything was fine until next morning. Finally, took to dealer and took navigation system (brain) was not functioning which also affected Radio was draining battery. The cost to replace drain was approx $2,000. I asked if there was any way to shut down system to avoid this happening until able to replace brain. They were able to disconnect system. The only problem with doing that is no radio, no disk player or navigation system. I can deal with that right now, because, I have iPod with this cool adapter with speakers for iPod and phone with internet for navigation if needed.

    I forgot to respond to the coolant light issue with my solution Land Rover technical service bulletin #TEC 260203 addresses this issue The specific gravity of the coolant has to be 1.075 with. 50% Antifreeze mixture. Spec gravity testers are inexpensive and available at most auto parts stores. Some stores rent out tools and they may be on the list of items they lend out.

    Concerning battery drainage as I stated originally theses cars all have this problem, solutions suggested include but not limited to constantly running Hard drive cooling fans to security system waking the car up when other people use their wireless remotes to open cars nearby, some modifications of frequency of the Land Rover wireless have been suggested but I doubt they work. I have not heard of Nav systems draining the battery, there are numerous faults that do occur with the units, failure occurs if water leaks into the inner fender well damaging the unit. Also the car was 90% BMW right down to the cigarette lighters. I like to call them BMW X 7's. As such the Nav systems are compatible plug and play with BMW units, those units DVD based will plug right in. I have seen them available every once and a while on E-bay for around $500-600.

    The Navigation is prone to water ingress from the E pillar area, once this happens the Navigation ECU stays awake and causes a 90mA draw on the system, draining the battery. Several of the Audio components are located in this area and have similar issues. In the later models, the phone module is usually the first to go.

I'm sorry I have to disagree with some of the comments above. The early HSE's do not have a heavy battery drain provided that they are not faulty. Vogues may have a large drain but the whole point of buying an HSE was to avoid dreadful ergonomics that can with the navigation touch screen and to get a second multi-format CD player instead of the archaic tape drive in the Vogue! It wouldn't surprise me if that navigation unit is a source of trouble but your 2004MY HSE doesn't have it. Mine is ten years old, still with the original battery and starts first time even if it has been left standing for a month. However, there are two issues with this vehicle that you should be aware of: First there was a software fault in the BMW sourced air conditioning. The system failed to acknowledge that the car was switched off and if the ambient temperature inside the car rose it would switch on the fan to cool the ecu. So if the car was sitting in the sun in a car park for any length of time it would flatten the battery. New corrected software should have been loaded by the dealer at the first service after about mid 2004. If this wasn't done that might be your cause. The second point is that the batteries in the L322 have memory and you may not be getting a full charge. To recharge one properly you have to put it on a special charger that discharges it completely and then recharge it from scratch. This takes about 24 hours. Other than that I am afraid I can't help you. Good luck.

2004 range rover hse key will not turn after i replaced battery

I have had the problem with my 2003 2 years ago and recently happened again.
I have a Range Rover specific scan tool and determined nothing was wrong with the security system, etc
The igniton switches do wear out and replacing the switch will fix the problem, but before this try spraying the key with WD 40 insert and remove it continuing to spray the key, wipe off all dirt that will show up on the key as you do this.
It took about 20 cycles of this and then my key began to work, continue spraying then cleaning key off a few more times for good measure.
Mine now works like new. I am sure though that I will have to replace the switch at some point.
Hope this works for you, good luck

Why wont ignition make contact 1998 range rover hse

Sounds like the ingnition switch or cylinder lock. Was the truck stolen?

If they removed the ignition switch off the back of the cylinder lock then that may be your problem, that may be the reason why you do not get the spring action at the end turn of the key. look at the rear of cylinder lock and see if switch is removed.The other problem may be the cylinder lock may be broken, remove the cylinder lock and see if the arm that turns the switch is broken.that would also cause the problem you are having,
Let me know the results. good day

I have a 2004 range rover hse. I received a "stop engine oil" message. I just had my car serviced and had a oil change from the dealer 2 weeks ago any ideas?

check the oil level at once, sounds like a filter is leaking or the drain plug....if so, do not drive it, rather, have it towed back to the dealer...
