Fuel delivery problem then? It sounds like while "waiting for the beeping stops", the fuel pump will come on and deliver fuel to the injectors? So maybe there is a fuel leak somewhere?

 

[Funfgang]

that would make sense...cause ive been loosing gas milage...although, ive heard this is due to the ethanol used in the gas now...




this sucks

I've always turned the ignition to position 2 and waited until the beeps stop before starting... yet I still have the "cold start problem" intermittently. I didn't know about the fuel pump being "primed" during that time, but I have heard about the SMG hydraulic pump.

Thanks,

The "wait until the beep stops" approach does not work for me. I thought that the replacement of the expansion tank part would solve the problem; I was wrong. My M3 did no start on the first attempt for the past 2 days. I agree with you guys that it must be a fuel delivery problem. I will contact BMW to complain about it; they have to issue a TSB to fix the problem. We might have to petition them.

BMW NA said they are unaware of the M3 starting problem and recommended talking to the service manager. I'll talk to her.

I had this problem on my '05 just after I got it about a couple of months into it. Took it into service and it was running smooth again. Now a few months later same thing is happening. Right now I'm due in for service again as my counter is near 1K so Im going to bring it in.

Unless someone finds something definitive looks like it will just come and go. Take it to the service center and have them fiddle with it.

 

[bmwphd]

Have you tried this? 1) Put the key in position 2, wait for the seatbelt beep to go away, 2) without depressing the clutch pedal move the key to the start position and hold it there for a couple of seconds (I hear some mechanism working), 3) start the car the usual way. It worked for me this morning but I have to reproduce it several times to see if it really works. I figure this is less harsh on the car than actually having the engine crank and choke on the first attempt.

Loss of fuel pressure overnight

ok, it looks like we need a petition to BMWNA...this is WAY to many 06 48000-60000 dollar cars having this SAME PROBLEM

I may be wrong, but in all my experiences with fuel injected cars, going back to 1981 Jaguars (German Bosch-Jetronic), in cold start problems of sorts where you have to prime fuel system by holding the key in On-position, nearly without exception the culprit was loss of fuel pressure over time. Overnight, for example. This was due to a tiny leak in system, even on connectors. As some posts show, fuel expansion tank, for example. Sometimes, faulty (leaking) injector(s). I doubt any of these would show up in diagnostics, but may be? My '01 just started to have this problem, I plan to check all fuel system out. I remeber replacing injectors and pressure regulators on my early cars. But these leaks can be anywhere, including fuel pump. :dunno:

i friggin hate this...i dont prime it, it always starts first time...but sometimes is kinda hesitant...dumb as hell

It has to be a fuel delivery problem. I took the car to the dealer again; they will let it sit overnight and try to reproduce the problem in the morning...

 

[Funfgang]

^^^ i did that, and they dont find anything...its gay as ****...i called BMWNA and obv. they have no idea about the problem...this sucks.

So at least two of us brought it to the attention of BMWNA. Does anybody know how all of us can file a "formal" complaint, petition, etc? I don't want to spend all this money on this car and get frustrated every time I get into it - I bought it to have fun.

 

[Funfgang]

^^^ I know, im sick of this and NO WAY do i want my car in my dealers possesion for 4-5 weeks...cause it would probably take them atleast 1 full week to find out the problem, 1 week to actually get their act together, 1 week to order and install, and 1 week for them to tell me they did something wrong...im just not happy with that...geez...I hate BMW but thier cars are too amazing...

loud air pump?

When I start my 06 M3 in the morning the secondary air pump is very loud; it turns off after 10-15 seconds. Does anybody else have a loud air pump on their M3? My car is in the shop for the cold start problem and the SA said they would replace the secondary air pump. To me that sounds like eliminating the effect and not the cause but let them have a try.

On another note - of paranoia that is - does anybody think that BMW put the engines that did not pass muster in the previous years in the 06 production cars?

 

[M3SMG02]

Well, for me, its been a solid 2 weeks so far this has been happening. I tried all suggestions here, but still the same thing. Im outta warranty, so I dont have that luxury of bringing it to the dealer without them charging me oodles of cash.

I have aftermarket warranty, and I'll try an indie shop (Motor Works West, in Jersey, these guys know their stuff) and see if they can figure it out. I'll tell them about the fuel delivery problems discussed here. I'll keep you guys posted.

 

[bmwphd]

they did not fix it

They replaced the secondary air pump which was very loud but the starting problem is still there. I'll take it back to the dealer - this is so frustrating.:bawling:

 

[Funfgang]

your in delaware...im in philly...its tHE GAS!!!!!!!

 

[bmwphd]

your in delaware...im in philly...its tHE GAS!!!!!!!

I guess we have to switch to jet fuel... :idea:

I think there's a fuel leak somewhere; otherwise why would it always start on the 2nd try?

Have you taken your M3 to Otto's?
