BMW 320 Diesel - Smokey when left running! HELP!

Postby tracey_vsg » Wed, 25 Mar 2009 11:38:06 UTC

Hi everyone!

I'm new to the site but hoping that some of you can help :? I have a 2003/53 320cd Sport Coupe. Recently, it has started to become very smokey if left running idle for even a couple of minutes. For instance, I dread stopping at traffic lights because when I pull away the smoke left behind me is terrible :oops: although sometimes it is worse than others. A few weeks ago I pulled away and I couldn't see the street behind me! What an embarassment!

I took it to Douglas Park BMW and they did a diagnostic test which reported the no. 2 heater plug was gone. I had this replaced and still no difference. I then took it to another garage to have the turbo checked and this appears to be fine - no movement at all. I am at my wits end so any advice would be greatly appreciated!! :)

Many Thanks
Tracey

Have you checked your EGR valve, could be sticking open which might mean under idle load, a greater proportion of your intake air is non combustable.

It is easy to take off yourself and check. Can be cleaned easily too, read the threads on here mate.

I'll second that, 95% chance stuck open. Best to ensure it is closed and just disconnect it. Makes a negligable difference to the combustion temps which promotes a fuller combustion anyway. Your car will perform better if you remove the vac pipe and plug with a screw or similar.

Good Luck!

Hi tracey sounds like a fuel issue is the smoke white/blue or black. Also has the car had any mods ie.. mapped/tuning box fitted is the problem all the time or just when the engine is cold?

WOW! thanks for the responses! :o

I haven't had the EGR valve checked but will definately get that seen to. Cheers for that :wink: Fingers crossed thats what is it.

The smoke is blue, which I believe is oil related? Please advise me if that changes the fact it could be the EGR valve.

As far as I am aware the engine has never been modified and I'd had it for over 2 years. Its smokey even when the car the car has been driven for at least an hour. I took it about a 60-70 mile motorway journey to see if that help but it hasn't really made any difference. It probably doesn't help that I only do short journeys now I have moved closer to my workplace.

Thanks guys!

correct when did the car last have its engine oil changed?
the smoke could also be caused by the engine breather being blocked with old oil.Has this part ever been changed?

I had a full service carried out about 200 miles ago, which was after it started being smokey. It had an oil change, oil filter, fuel filter, air filter and the no. 2 heater plug changed.

As far as I am aware the turbo breather has never been changed. Do you think its worth giving that a try as well.

I am having the EGR Valve checked at the weekend so fingers crossed :(

If the smoke is blue then this points to oil that is burning, the crankcase/turbo breather 'must' be changed as a priority... part of the "i purchased a 320d what should i do" bible. This could well be your problem? How is your oil level, smoke can be caused by over filling.

Best to disconnect or clean your EGR anyway.

Thanks for your reply. I shall get the turbo breather changed as well, anything to try and get this problem resolved.

The oil levels are fine, although it must check its again as it was about 2 weeks ago I last checked it. I always keep oil levels below the max but never over or excessively under.

I am definately going to get the EGR valve cleaned this weekend and possibly disconnected.

I appreciate your help.

My money is on the breather.
I would change it ASAP before causes damage to the turbo.

do you know what oil was used in the service?

also as stant1man posted over filling the oil level will cause blue smoke.

what mileage is your car?

Hi

My money's on the crankcase breather as well, mine's a 2003 it had done about 100k and the old loo roll style one was clogged like tar.

Fit the new plastic vortex style inner into the old casing, costs about £17, never needs changing again.

Tony.

Thanks alot, I will get that changed at the weekend too. I have been reading on a few websites that the crankcase breather should be changed about every 20-30k miles and I'm probably correct in saying that it'll never have been changed.

My car has just over 75k miles on the clock. As the service was carried out at a BMW dealer, I am assuming it will be the correct BMW oil that has been used. When I'm topping it up I use Castrol 0W-30. Is this the best I can use?

Also, where can I get the new plastic vortex style inner for the old casing?

Regards
Tracey

Hi

See attached page, order item 15 and you will get the new style vortex inner and 2 gaskets, or order item 11 and you'll get the lot - cover, inner, gaskets and bolts but it's about £35.

Hi

Any BMW dealer will order it for you but if you phone round a few you may find one who has it in stock as they are now changing them as a service item.
