Back in 2007 when my FL2 was brand new, the battery went flat on day 4. This was because I had not set the alarm. LR assist said that as the battery was flat , and of the Calcium type, it would need recharching at the garage as the engine alternator would not recharge to 100% full from flat. (Normal day to day recharging on a nearly full battery was ok by alternator). So as you have faltened your battery, presumely even with engine recharging, you still don't have a fully charged battery.

You are unlikely to cause damage. The starter motor will get hot after a while and they are actually less efficient when hot, ironically. It would more likely be terminations issues if it's been an issue with 2 batteries. Primary suspect would be the chassis bond for the negative terminal. Never looked to see how/where it's done and can't right now (in Germany) but there will be chunky cables with heavy duty crimp rings or similar bolted to the engine and/or chassis. If the bolt isn't tight and clean or the crimp isn't secure then you can experience resistance in the terminations resulting in a voltage drop under high current loads (there's no higher a current load than when starting). The actual battery terminals are equally as important of course but since it's been changed and presumably correctly so, it probably isn't the issue but easy to check and worth doing so. **TAKE CARE WHEN USING UNINSULATED TOOLS ON BATTERY TERMINALS** It's possible for a termination to vary with temperature if not adequately secured, simply due to expansion/contraction. A final point is to make sure lights/heated seats/screen heaters etc. are off when starting in cold weather. Also, a preheat of the glow plugs (diesel only) can often help. Press start button without clutch (manual)/brake (auto) depressed until dash lights up. Wait 3 or 4 seconds - press pedal - start as normal. This uses some initial current for the glow plugs but will encourage firing, therefore hopefully shorter cranking time. |

I think insulation wouldn't be feasible. Your best option is to use a trickle charger when not in use (overnight etc.) but access to mains power might be a problem if it's in a car park for example.

Thats pretty much it, ill try it in the morning and see how i get on, just difficult for a garage to diagnose as by the time i get it there it will start just fine!!

Next time it does it have the Land Rover Assist guys out straight away, they can diagnose the fault and then you can get it sorted with the dealer. |

I have suffered the same problem with starting the car in the very cold temperatures recently, -10. The glow plugs should help with starting in these low temperatures and I have had a message on the dashboard similar to "cranking will start after glow plugs have heated",but failed to start. The battery was new in January but i put it on charge to top it up and the car started the next morning, although not in as cold temperatures.I have not had any problems since.There does seem to be an issue with cold starting in very cold temperatures. |

Strange. I've had no starting problems whatsoever. My FL2 sits outside, doesn't get used every day and it still fires up first time.

I have the same problem! Only when it's say -6 and below. I have a fully charged battery, well it crankes over with no hesitation. I bought the car second hand with 3 months cover, they have agreed to change the glow plugs, fingers crossed. It's being done on Monday so i'll report back the next time it's cold. Funny thing is when i press the start button i've never had the delay, it tries to start straight away. I have tried the two stage start but it doesn't seem to make any difference.

Ah, something is wrong if you don't get the delay. The glowplug timer isn't working for some reason. The glowplugs arn't getting hot enough. No wonder you've got start problems.

I have now gone through the hole non-starting crap with my FL2. Problems started below -5 and did also end in flat battery and several click click on all electronics.

Hi, I picked up my 07 HSE just over a week ago and I have the same problem - cranks and cranks below -5 but won't fire. I do not get the glow plug heating lamp on the dash when I start the car. I have tried switching on without depressing the clutch in order to try to pre-heat before cranking and that did not wotk either. Is this a common problem or just one the lies hidden until the temperature plummets? Does anyone know where the temperature sensor and the control unit for the glow plugs are located?
