Hesitation continues at low RPM

Has anyone found a resolution for the hesitation issue?

The hesitation problem started shortly after the fuel filter was changed and has gotten more consistent but only happens at low RPM. The fuel injector service was performed and high quality gas is used.

There hasn't been a code until this week when I got "increased emissions". The mechanic got some random codes relating to the O2 sensor but he doesn't want to throw sensors at the problem. Replaced spark plugs, checked all the coils and the hesitation persists.

Any ideas? Thanks

Miss-fire cylinder 2

Isolated the problem to a miss-fire on cylinder 2 that happens at low rpm (about 2500). Has anyone else experienced this issue? Any resolution?

Help!

I too have the increased emissions issue, and possibly the hesitation issue at low rpm. I'm taking it in today because they found a leak in part of the re-circulated exhaust system. They're going to replace the part and do another smoke test to make sure it's tight. I'm hoping this will not only clear the alert but have some impact on the slight (and not always consistent) hesitation I get at low speed/rpm. I'll report back with their findings and my post-service experience.

Back from the dealer where they said it would be an hour wait and it was. They replaced the crank case vent valves which were faulty, re-smoked and found it tight. I don't want to get ahead of myself, but I didn't notice that hesitation I was getting before (it was never huge and kind of random). So here's to hoping. I'm going to drive it over the weekend and bring it in next week for them to do a courtesy emissions test on it. You really can't beat quality service like that!

Sigh.. and the hesitation is back. It's only at low speeds/rpms though and it's just a mild to moderate surginess... Drives great otherwise, so it's frustrating that the off the line acceleration is basically gutless right now.

I tried that and though there is more power/rpms, it's still not transferring it correctly I don't think. That combined with having the trans overheat twice over this weekend (admittedly while driving through the mountains both times) I think that may be where my problem lies. Ugh.

welcome to my world

problem is way more serious here

how many miles you guys have? i have 87k miles.

remove your head covers clean it up and let me know how good it is.

You know.. mechanics at stealeships are idiots!!! they don't know a sh%^&t they charge you all the time

just open your oil cap and tell me how much vacuum you have there?

also do you have alittle bit of shaking when you first start the car??


also make sure you valvetronic levers are ok, not worn out

No shaking when it starts, at idle the rpm needle bounces between 6-800rpm, though not in an overly rough fashion. I'm taking my car in tomorrow after work and leaving it with them for a day or so until they can diagnose it. I just got the dang thing a couple weeks ago, so hopefully they will do right by me. Anyway, it has 62k miles on it and from all the research I've just done, it's a known issue. I was dumb not to look into this year/model this thoroughly, but I feel in love with it at the dealership and during the test drive it was fine. As it is though, I already had the crank case vent valves replaced (they were cracked and the vacuum/smoke test revealed only that so far). We'll see.

CCV hoses and valves can cause this issue.


its not rough idle... for someone it would sound ok, but its not silky smooth and light as it should be.

Just dropped off mah baby! They're going to go over it tomorrow and see if they can identify the issue. I sent their service manager a lengthy email with a full description of symptoms as well as links to various (other) posts about this issue, including a few links ya'll may find interesting:

http://www.aboutautomobile.com/Compl...c+Transmission
http://www.arfc.org/complaints/2005/bmw/545i/
http://www.insideline.com/bmw/5-seri...-bmw-545i.html

Hopefully that will give proper credence to my complaint as well as give them some starting points. I'll let ya'll know what the verdict is once I find out. Until then, *nervous*.

i'll keep my fingers crossed for you-tho my car has 87k miles on it and there's a slight shake when it starts,with the tach needle bouncing a little dealership told me there's absolutely NOTHING wrong with the car when i took it in- what a surprise that is! i personaly was looking forward to buy e60 545 for a few years,and after having 2 740s back when they were still cool i wanted to buy 545 but got M5 instead-which was was amzing but comes with crushing depreciation and a huge maint. bill! so i was looking into 545 more than ever,and now that i got it-i think it would be the last bmw i gonna buy... good luck

Well, the verdict for the trans over-heating issue is the transmission thermostat needing to be replaced. I guess it's stuck mostly closed and isn't working properly. So they're getting a part from BMW and replacing it tomorrow. As for the hesitation issue, they didn't find anything specific. No codes, no obvious mechanical problems other than the trans thermostat. I had given them some links to other people's complaints and they're aware of this issue on the e60's but I'm not sure there is anything specific they can do. So eh, I'm glad they found something that might have caused further issues down the road, but I'm left in limbo on the hesitation problem. It sucks not having that off the line acceleration I should be getting from a 4.4 liter v8.

Mobody knows how to fix it (( they say it's okay) lol!!!
BMW v8 suck!!! That's why they switch to online now.
I think problem is sitting in the heads they are clogged!! Not enough air the mixture is rich!

check the hose between the the oil dipstick pipe to the bottom of the intake manifold,,,just move the air flow hose and inspect it for cracks,,,,it has like a net cover around it ,but move the hose gently to se if you notice any abnormal movement,,hose is like $20 or less,I always have at least 5 in my shop,,,frequent problem and also sometimes do not show codes

Thanks bro!

Suggestions for how to get back there? Do I need to take off the cabin filters housing?

I dunno if this is the same thing, but my '08 550 has a dreadful start from a full stop. Unless I take-off under stiff acceleration the car completely bogs down like it's not getting any air, is this anything y'all experience?
