300tdi cold start problem

Postby littlelegs » Fri 23 Mar 2007 2:33 pm

:shock: Hmm. Well had to set off for work on tuesday morning at 4am. Slept in - typical. Went to start the landy and although it would turn over it was v slow and wouldnt fire the engine.

Not having any time to mess i took our girts car with a view to looking at mine later. When I got home it started first turn of the key. The only thing that had changed was the weather. At 4am it was minus 4 or 5 and by the time I got home it was warm and sunny.

I checked the battery and it was a little low on charge so i charged it back up and it showed full within 4hours. Put it back on the car and it fired up 1st go. The following morning it was about minus 2 and again it was slow to start. The battery is over 4 years old at least.

Gonna check the glow plugs this weekend. Any other ideas?

Hi, your battery is over it's sell by date and I think the best thing to do is change it. Cold weather will take the edge off your battery. The guarranty they give on batteries will give you a clue to how long the unit be reliable.

There are many ways to test batteries and one way is to look at the cells to see if they are dry.

I change my battery every two years without fail and never have a problem. These 300tdi's need very little turning over to fire them up even in cold weather without glow plugs as they are direct injection but you need your cranking amps to feed the starter. A high amp hour battery is good in very cold weather.

Not much more to add, but to agree with what has already been said. My 300Tdi ES takes an extra couple of turns when really cold, and this varies with the amount of alternative fuel I have mixed in :D . Put a better battery in and now I dont notice the difference...

when you buy a new battery...........

Postby trailerfitter » Fri 23 Mar 2007 8:18 pm

make sure the [half shaft] fits as some bigger batteries won't fit under the clamp.
If you go to a motor factors that most garages buy from they should be able to help you out and give good advice.. Generally if you pay for a battery with a good life guarranty it'll cost alittle more but will be reliable...........good luck chap :)

PS Take the motor there so you don't have problems fitting the damn thing.

Here's another tip - when its very cold, put your foot on the clutch before starting for less effort on the starter motor.
