Idle issue?

carlili4190 · 06-04-2011, 06:51 PM

Sometimes when I start up the car(35i) the idle seems to jump. It looks like the car is being revved up. IE the car starts.. Idles at ~600-800 and then jumps randomly to ~1700 RPM and then back down to ~1000 and then back up to ~1700RPM. It does this a couple of times and then settles down to ~600-800 RPM. Does anyone else have this issue?(if it is one?) This also doesn't happen all the time, just on the occasional start up

Yes - I get that occasionally also…edit - I have the 35i also

colton_matthias · 06-04-2011, 08:04 PM

I think it happened twice to me... I wonder what it is.... :S

Nahoa · 06-04-2011, 10:06 PM

Yes, it's happened. Used to happen with the 330i, too.

I get this on both my bmw's. Can't say if it's 'normal', but I'm guessing it is b/c I get it on both vehicles.

Every time for a cold start. I spoke with BMW NA about this. They said it was normal. It still bothers me.

I can see it on a cold start. However, it happens in a garage and it hasn't been that cold in Chicago recently

Mine did it once when I was getting ready to back out of the garage in reverse. Glad nothing was directly behind me......

No I mean cold as in the oil temperature at startup over night.

Never had it happen to me but the X3's programing worries me in general. Normal mode & sport with only chassis selected maintains 1.2-1.5k rpm when driving a steady speed. This seems quite low and if driving at 2-3k rpm the engine starts to get quite noisy.

I have this problem too - on my 5th BMW and 3rd turbo engine variant. NOT NORMAL. The X35d doesn't do it, never has, and the Z4 35i does not do it - never has one time. The X3 has an issue and I expect it to be fixed.

Let me tell you something - I love BMWs, we all do or we would not be on this site. Let me tell you something else, BMW NA will screw you in a second to save a buck. I am sure this will be fixed with a software re-program of some type but it will take us hounding the dealers.

paul386 · 06-06-2011, 08:55 PM

My 35i does it occasionally too. There is nothing consistent about it... I would say 1/5 to 1/10 starts it does it.

Powerrunner · 06-06-2011, 09:20 PM

My 35i also does this once in a while when the car is cold. Does not happen frequently just a half a dozen times thus far. Have had my 35i since Febuary.

Baccars · 08-20-2011, 04:52 PM

Just bought mine 3 weeks ago and it started doing this at 700 miles. I have had it back to the dealer 3 times and have gotten the cold start story. Sounds like I am wasting my time until they agree and get a software fix

charlie k · 08-21-2011, 10:52 AM

I have same problem/ never know when this will happen . also when driving i get loss of power. i was told this is the hi pressure fuel pump. untill the service dept sees it /they wont do anything.

charlie k · 08-22-2011, 06:13 PM
