7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Talking BMW 730D 2006 Running issue please help

I have a 2006 BMW 730D.....

Basically driving home one evening it started "juddering" Missfiring" as slowing down and idling ruff on idle...

Now its got worse... you go to pull away it just says engine reduced power and then cuts out the engine and you go to restart it and nothing, push start again and it fires up.. it takes longer to start now but really have no idea of what the problem could be... the cars done 80k.

Any help would be grateful as really need the car on the road for work journeys. Thanks

That sounds to me, that you're problem is throttle body related. It's a common fault with E65's.

It's going to be an intermittent problem, which gradually gets worse. These code readers are to be taken with a pinch of salt. The codes provided may not necessarily, be of any use to a BMW garage. Ultimately, you're going to need to take your car to the nearest reputable BMW specialist and pay for an electronic diagnosis. They'll be able to tell you what the problem is exactly and how much it'll cost to put right.

If, it is the throttle body, it ain't going to be cheap, I'm afraid.

I hate to correct you Paper. You've been so knowledgeable and everything else. But I think you missed this one. I believe the 730 D is a diesel. That's the D designation. It would not have plugs or coil. It would have glow plugs or some type of heat to start it but after that they make no relevance to the running.

This site does not really have a lot of diesel owners on it. Found this on a UK site. Realize it's for a five series. However the engine might be the same. Worth a shot looking here.

Did you fit that injector youself?

your a brave man if you did . The fuel rails runs about 3000 bar of pressure . Enough to lob a few fingers off.

After you fit the the injector you need to code it in the DDE. each injector has a different no. And its stamped on the injector. You need to put this in the DDE.

Reading the first post I thought fuel pump , maybe the electric in tank pump . I read something somewhere a while back regarding the juddering issue with bmw diesels which says it`s the high pressure mechanical pump , maybe the electronic diesel control ( EDC ) on the pump .

Tried to find that info , no go , but I found other info which may help .
First , a couple of UK companies can repair your pump if that is the problem .

And some posts from other forums by folk with the same codes , different remedies

Mein Auto: 730d sport
did you sort this issue ? just bought a 730d , it was running great but I still removed and blanked the swirl flaps and had a remap with EGR delete , 150 well spent and mores the point , prevents any of the usual 3.0d issues , I would have all your injectors reconned but before that , whip the inlet off and see if your swirls are working correctly ?

Mine does a very similar thing (730d) but only when just started - runs fine for a minute and then starts to shudder for about another minute then fine for rest of the day (sometimes stalls), I have had no luck working out what it is but presume that it's not a injector as it would be constant, I was presuming that it would have something to do with fuel pressure (was going to use inpa to read values while running to see fluctuations) but very hard to find as you can only test once a day and no errors in memory (yet to do glow plugs)?

what year is yours (mine 05 facelift) - I was not sure if the flaps actually caused problems on this car -I know there was a problem with the 5 series but I thought it was sorted on this model (ie they don't fall into the engine anymore) - I also would have removed all the injectors - local shop here will check and clean them for 15 each and can recon if required?
