Car Wont Start When Cold - BMW Forum

mcmanamon · 03-02-2005, 06:31 AM

Hi guys – I would apreciate if anyone could help – I have 325i E36 convertible 6 cyclinder. And the car will not start when its cold ONLY. I have taken it to a garage they were very help full – there is absolutely no errors on the computer – so its running like a dream – however when its cold (about 1degree C) then the bitch won’t start – the guys at the helpful garage have no idea – but one of their mates at BMW said it’s a faulty block – common problem that BMW will repair free of charge – the only problem is convincing BMW will be the difficult part – he said – so I hopped on this forum to find some evidence but I can’t find any. Does anyone heard of the same problem and if they have had the engine replaced what was the best way of approaching BMW – lets admit it they are slimy bastards.

PS love the guys posting pictures of there nude girlfriends – keep up the good work

regards

Your battery probably needs to be changed. For each degree drop, there is a significant decrease in the amount of power a battery can put out. If the battery is weak, the car won't start.

You can test if the battery is the problem by trying to jump start your car.

batteries usually die in the cold.

doess it turn over, or does it do nothing

Thanks for your reply - the battery will turn her over for hours - anything other suggestions - when the recovery guy turned up and he connected his leads we still had the same problem

I tried to jump start it but it would work - I'll try again

I have been thinking about your car and it has to be software or plug problem. The old formula of suck, push, bang, blow hasn't changed. So if gas and air is making it into the cylinder and it is receiving an electrical current, it has to work. LOL... in Canada one degree Celsius is a warm winter day, not cold. If "cold" were an issue, then all those cars in Canada would be having troubles big time.

I'm putting my money on a software or sensor glitch.

It is possible to have a battery that operates fine under normal temps but its the cranking amps you need to check on the battery. I was having the same problem when it got to 10*F. Except my battery was fine it was the battery terminal that was just loose enough. I wiggled it, tightened it and BAM! it worked. Anyways what I am saying is I have had batteries work just fine once the temp was in mid range but go bad when it got cold out. You can take the battery to a shop to have it load tested. Which will tell if it has enough cranking amps. It may still have 12volts but not enough cranking amps. Good Luck!

BTW tell your mechanic that your car isnt a DIESEL! Its not like it needs a block heater or anything.

crank sensor or air flow meter.

ENGINE TEMP SENSOR!

you have a heat gun... blow some hot air onto that guy(but not too hot or u will melt the insulation) and start ur engine. if it starts, there's ur answer ;-)

Try replacing air filter and air flow regulator

zackpc2010 · 02-16-2010, 10:41 AM

It looks like your battery is dead

92cleanbeam · 02-16-2010, 12:55 PM
