"EGR valve is nonsense!"
How smokes the car is not from faulty EGR valve! Problem is what the motor oil leaks is from the axis into the turbo and ill axis mountings!
The oil goes into the exhaust pipe
and intake it back into the engine where it actually burns (white smoke).
When your car no more acceleration power
, problem is a associated where the turbo pressure back to the intake is not to higher as it should rightly be! When you run at full throttle to hear such as the whistling sound from the engine, right? If so, believe me that the turbo is K.O! and not AGR!
Tip at the end of the letter: if AGR can not work, does easily unscrews and clean it, does it works too properly!
Is it acceptable solution over the recommends that the excludes out the AGR lower emission system from the motor, right?

Loss of power some white smoke


If you have the 3.0 liter engine the most common problem for white smoke and loss of power is the vacuum regulator/oil separator, they are built into one piece located under the intake manifold. There are four hoses that should be replaced at the same time that go to it.

Driving along lights dimmed, instrument panel died, loss of power then engine cut out & wouldn't start. Starts with a jump but when i turn key to heat glow plug, instrument panel goes mad


I assume there's a problem with alternator. Check the grounding to engine, check continuity of a positive wire between alternator and battery. the energizing voltage should be checked as well. Might be the bad connection between battery and vehicle body grounding. Diesel cars are sensitive even in a little loss of connection and rust in the connection points.

The oil in the engine is cream and is smoking


It's quite likely to be the head gasket, but here are a few cheaper possibilities to consider it's it's not overheating or suffering any great loss in power.

If it's a diesel, white smoke can be caused by unburnt diesel which could mean incorrect injector or valve timing or a leaking injector.

If it's petrol, have you driven in deep water? the cat could have water in it which also produces white 'smoke'.

I have bmw 525 diesel. I see excess white smoke


white smoke from a diesel is usually lack of fuel, black smoke is to much fuel, check your fuel filters for restriction. this is providing that the smoke is not coolant in the exhaust but if that's the case it should be overheating. also if it is cold were you are you might have a fuel gelling problem that will also cause white smoke. just put some anti-gel in the fuel and see if the problem goes away.

Hi, I have an BMW X5 56 plate 3.0diesel. 41k miles. I have noticed that there appears to smoke coming from the exhaust upon acceleration. This is happening all of the time. Also, yesterday I lost power (as...


Have a go at the Positive Crankcase Valve (PCV). its located under the engine cover towards the rear of the engine in an odd shaped black plastic box alongside the fuel injectors, Dont pay BMW the Big dollars. Buy a filter for $50 AuD on Ebay or the whole unit for $120 AuD. You have to remove the engine covers to do it but thats not so hard really, just a bit involved and takes 10 mins to remove the engine cover. The actual filter is a throw away job, but the whole PCV assembly is just a degrease and clean. Its held in place by four small hex headed bolts, when you lift it you'll find the small can shaped filter pinned underneath. Swap the filter. its VERY unlikely to be your turbo at 41,000m.
The PCV is a known issue that causes smoking and even power loss, BMW actually did a retrofit kit PCV for use in cold climates., Are you in somewhere cold? and another possibility is not using the correct 'Winter diesel' in a cold spot. Very common fault for X5 owners going up to Thredbo or Perisher snowfields in Australia for the first time!
Happy Motoring
