SOURCE: intermittent not starting

BMW engine is aluminum engine. Watch out , don’t let the engine over heated too much.

According to your explanation, sounds like your engine is over heated, I like to know , how hot the engine was when your BMW stalled and you have to wait around 45 minutes, after you started your car again and how long can you drive and get it hot again.

Any aluminum engine, we must watch out very carefully, sometimes just one time over heat, the engine will be damaged very badly, as soon as you have over heat problems, you have to check the following items.

Hose, water pump, fan belt connect to water pump, thermostat, coolant level, oil level, electric cooling fan should work normal, Check your radiator circulation, timing etc.

Check the coolant in the radiator see if there is oil,
Check the oil cap and oil stake see if there is white steam, if you see something like what I mentioned, that possibly your engine has blew up the head gasket or the engine cracked already, hope not, but you have to watch out and check it right away.
Sometimes during the summer time, if you feel your car is hot or you smell burning coolant and do not keep driving, maybe only driving several blocks or several miles, you are going to completely damage your engine.
From my Union 76 Service Station long time experience, I had so many cases about the aluminum engine damaged by over heat even my own BMW 530i.

Please check your car as soon as possible. Good luck.

By the discription you give this sounds like it may be a starter motor problem.

You are smelling burning antifreeze. likely a head gasket but only testing will determine that for sure...Do not drive it. get it to a shop or more damage is likely.

SOURCE: Clouds of smoke

Hi All.

I am a BMW technician and i see this problem daily. There is a filter on the top of your rockercover. it is called an oil separater or a breather filter. you can only get the filter at a BMW garage so if you go to stores and ask them for this filter they will know what you are talking about if you tell them you are after having your turbo replaced. Fit this filter and you will notice the smoke will get better if it does not go away completely you might wait another 3-4 weeks and replace it again. hope this helps.

Regards,
Shaun

My audi19 tdi if I let it stand for a while then I have to crank it several times before it starts,n clouds of black smoke comes from da exhaust,what can n da problem


Should have glow plugs installed.
try leaving the ignition on for a few seconds rather than cranking.
leaves time for the plugs to warm up.
may need replacing.

Sounds like you have a diesel! If not then your in need to tune-up, timing could be off, 02 going bad, or bad gas.

I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

My 2004 745li bmw leaves white smoke when driving off sometimes


This widespread problem is the one part no one thinks of: ENGINE VACUUM PUMP.it runs mechanically off camshaft;once seal leaks,oil from camshaft housing enters vac oump and becomes ingested by engine,therefore exiting tailpipe,water accumulation in by product of catalytic converter changing smog/carbon to water/vapor.REPLACE VAC PUMP AND SEAL ,SMOKE WILL STOP!!!!

Car overheating while driving but not in idle


Head gasket, if you are lucky it might not need a new head.

Smokes at idle, not while driving.


you have hit the nail on the head ,starting a cold engine and just leaving it to idle takes a while to warm up ,but driving it straight away which is what you should do get the engine warm quicker ,also reduces your carbon footprint.When the engine is cold it burns oil till the correct clearance and tolerances are reached .

When I turn on my car there is white smoke @ idle also when accelorating leaves a big cloud of white smoke like a burn out please tell me what's going on! Thank you


Your vehicle is 8 years old and possibly has 150,000 miles on it. You could be facing a ring job for the pistons and definitely a valve job that includes valve guides and seals. An experienced tech. will tell you after a compression check how bad ($$) it may be. Fortunately, you can shop around for a garage, some folks aren't so lucky.
