| Starting issues - an interesting one |
|
Hi all,
Heres a good one for you boffins to guide me on....
Car in question 2006 TDV6 SE, 49000 miles, full service history to date, no warning lights at all.
Last Sunday mornign after the cold day Saturday and snow, went to start the car, took 4-5 cranks before it fired. Whilst cranking the nav screen was dimming and brightening in time with the cranking. Once fired, all tickety boo.
Battery was original OEM unit, checked the charge on the terminals 14.5V at idle.
Me thinks, agh first real cold snap must be battery. So replaces battery with a top spec bosch with capacity near as damn it equal to the OEM unit.
Installed it Sunday and run like a dream since them.
Left the car yesterdya about 100yds up the road for half a day, started it and ran onto the drive, left overnight.
Bitterly cold night last night, went ot fire up the car this afternoon exactly the same as last Sunday - 4-5 cranks to fire and nav screen dimming and brightening in time with cranking.
Checked the output on the terminals again today, 14.5V at idle, battery sitting at 12.5/6 V with everything off.
WTF ? Spoke to local independent and asked about glowplugs, he said doubt it.
I am sure one of you clever sparks has seen this and can give me some pointers.
Thanks in advance all, great to knwo this site is here for such occasions !!!!!!

Glowplugs I reckon 
Go to the multiplugs on each bank and supply a feed to each pin from the battery with your multimeter in series and on amps or an amp clamp around the wire and see what each glowplug is working properly.
Should be around 15amps I think

Cheers Tawny
I've been trawling the site looking at other cold start issues.
It's odd that we've had quite a number of well below zero nights and the car has started tickety boo.
Just 2 cold nights that it hasn't.
I'd have expected it to be the same every start over winter.
Odd.

You've done the obvious one, the battery.
I'd be looking at the Starter motor for Brushes & undercut the Commutator...........
It sounds like it's loading the Battery in a regular cyclic way. It may be shorted turns in the Starter Motor or some other Binding type thing
Let us know how it turns out
Goodluck

Check for good clean uncoroded contact on the major battery leads. Especially at the far end of the leads. A vaccine does not stop you catching a virus, or passing it on, or getting ill from it, really ill. It does reduce the likelyhood of you dying when really, really ill.

Remove the engine cover and on each bank on one side you will see a brown multiplug and the other side will have a black multiplug

I had my local independent try on a number of different occassions to fix my same cold start problem, which the car developed last winter.
Battery was changed (had been same since new, over 5 years), but no difference.
Glowplugs checked, apparently a couple were faulty, and were replaced (no mention of any issues getting them out!)
At the last attempt, I was charged £380 for replacing the "temperature control ECU" - which I can't find any info about anywhere (can anyone confirm their cost?) - but that did seem to make a difference. All last week, even at -10 one day, it started first time.
Trouble is, at -3 degrees this morning, it started struggling again... eventually getting going with the usual plumes of white smoke out the back...
Also, FWIW, before the ECU replacement I used to get the "special programs off" message at every ignition attempt (which folk have attributed to battery isses). Now I just get an "HDC fault" instead.
Anyway, I'll update once it's been looked at again.

Hi there
Had the same problem all this week with mine. Car has been in the garage this week and had a "Mass air flow senor meter fitted...[not much change from £175][/b] and that cured it for one day. Back in the garage today as having the exact same cold start problems. Incidentally, after calling around a few garages just as an idea what it could be wrong....most had similar age Discos in with the same problem.
Back to the "easy start" tomorrow. Starts instantly with that and has no problems till dawn!
Cheers

Hello there,
Has anyone got any ideas? I too have just replaced battery but car still will not start, (has been -16 overnight here at the moment). Have spent mornings building little tent with tarp over bonnet and blowheater underneath. At -2 engine starts going. No faults showing until I wear battery out cranking it.
Will check glow plugs when possible to do without fingers falling off.
Bought this car due to living in country with snow and ice. Now pretty much housebound with family due to inability of Land Rover to deal with cold. Absolute joke of a car. Have had to replace usual things (as highlighted in forums), electronic handbrake, metal L bar latch in tailgate, climate control panel. Now front passenger door won't open, I suspect due to same piece of metal as tailgate shearing. Dealers down here charge a fortune and do as little as possible. This is supposed to be a heavy duty all purpose vehicle and as far as I can see I would be better off with a Renault 4.

My original Disco MY05 hse had this prob. First you think its the battery, so you replace it, then all well for a few days. then the problems come back.
Its your alternator. Happened on both my D3's. What happens is the brushes on the alternator wear down with time. If you get your car started and immediatly check batt voltage, you read 14.5 volts, and think all is well with the alternator, but as soon as you take some current out of it while driving,( heated seats, radio, elec windows, suspension compressor etc...) it starts to break down and not provide a charge. Thus your battery gets no charge while driving
Think of it like a flat battery. If there is no current being taken from it, the terminal voltage my well be up 11-12v, but as soon as you try to pull some current from it, the voltage takes a nose dive.
Susp fault, HDC faults etc all come part and parcel of a duff alternator. they are very sensitive to low voltages and will shut down.

Hello Mr. F... thanks for that, that does sound like a possibility given the circumstances. The car is now back up and starting on the old battery (charged overnight), aaargh, £129 down. I'll put in an order for a new alternator and see if that fixes the issue although I also will check glowplugs as well...
