/ Bump starting car
Am I right in thinking that by only having to heat the glow plugs rather than turn the starter motor there'll be less demand on cold battery and so more likely to start?
You might be able to bump it, but I suspect the battery is knackered - a good frost usually kills off the little bit of life left in an old one.
You'll have to repeat the process at the other end sadly.
There was definitely life in the battery this morning, tried starting it 5 times and still seemed to have life after 5th attempt just didn't start engine. Called breakdown, they jump started it. since then I've stopped/started it again 4 times and each time started fine really quickly. just wondering if its due to cold this morning. odd really. If it don't start tomorrow just hoping there's enough life in it to heat glow plugs so I can push start it.
You may be able to bump start it, but in my experience there's a 50% chance you end up with a still dead car, but at the bottom of the hill rather than the top..
Battery charger left on trickle charge overnight works. Not only charges the battery but heats it too.
Course, running your working car to the nearest Halfords to get said charger before it shuts at 8pm might help.
Original equipment batteries typically last 6 years and after-market ones 4 years. Some more some less. If there is no known reason for the battery being low and it is near the end of its expected life then at the next hint of a problem, bite the bullet and buy a new one. However, bad batteries have a habit of breaking alternators (and vice versa) so often a second problem comes along.
I agree, if your battery had enough juice to turn the engine for five start up attempts. Then I'd guess that your glow plugs aren't up to scratch.
Easy start works beautifully, but it is the kiss of death and engines quickly become addicted to it.
Personally I prefer the brand 'start you bastard'. It actually exists!
If it is weak any way a cold morning will be enough to stop it working as the engine will need to turn faster than normal to produce enough heat from compression to ignite the diesel in a cold engine block. The glow plugs help but they're never going to heat up 50kg of frozen cast iron. At the same time the battery is producing less omph than normal.
you might already do this but one trick which can help is to turn key to arm ignition (and the plugs) but stop one click short of turning the engine over. Wait for plug/coil light on dash to go out (will take longer in the cold) then switch back bff, do the same again but turn all the way.
pretty much - when you turn the engine over, the starter motor takes a lot of current which causes a volt drop across the battery (internal resistance). This in turn reduces the glow on the plugs. Same reason headlights dim when you start the car.
Simple question: how old is the battery? Unless the battery is recent, ie less than 2 years old, get a new one, they don't cost much these days, and you can easily do it yourself. At least you'll get up without the worry of will the bugger start?
Be careful jump starting though. You can knacker the likes of catalytic converters and the like if you are not careful.
