Ive been tooling around in the new 335 6spd my mom bought while my M conserves its miles:devillook

and I noticed the other day the car took awhile to actually start. I pushed the button and it cranked longer than I felt it needed to. It always actually starts but sometimes it will crank longer than normal.

edit: this was not a totally cold start either I had been driving it earlier.

Other than that it runs great, its very fun. Push the little button on the dash and its even more so.

What is the build date of the car?

Geez lets see, she took delivery pretty early on it. Its one of the first...Ill have to check tommorow.

That, sir, is most likely your High pressure fuel pump beginning to fail. Hope that's not the case, but that's one of the classic symptoms.

6000 miles with temps from below zero to 80+ and I've never noticed a difference in the start. It sometimes idles higher after the start, but the start is always the same.

Has anyone noticed anything weird yet on their 335? Starting or otherwise, since the car is still relatively new?

Starts fine, and already clocked 10K miles, except for a little rough idle right after the start (if car was sitting for longer than 8hrs). Otherwise all good...so far.

my friend's e92 is starting to do that too he took it to the dealer and had them check the fuel pump.... they said his fuel pump is fine, there's another thread on e90post about the same issue hope it helps:

sorry can't post link gotta do it the old fashion way copy and paste, still too new on this board... stupid rules...

Sorry to tell ya... but the hard start (long cranking) is definitely the fuel pump. That's what got us to bring ours in, and it took them 2 days to say it is the high pressure fuel pump. BMW has a technical bulletin about it.
Needless to say, it's now over a month and our car is still at the dealership, waiting for a new fuel pump.

Ahh...That thread on e90 is about fuel pumps, and even has a link to the TSB regarding the HPFP...

You ever consider lemoning the car and then turning around and getting into and '08?

I am wondering if it's worth the effort.

-Todd A.

Todd, we've considered it however it's the car we researched prior to purchase and still love it. I'd suggest that you share your thoughts on enacting the lemon law directly with BMWNA as that'll really get their attention.

I'd say they'd be willing to "bend over" as far as necessary to make you happy. Let's just say I know. :awink

Im actually quite amazed others have had this problem. I am going to go talk to the dealership about the fuel pump.

that does not sound good. Notice anything weird when you are driving it?

what kind of rough idle? does the car shake?

Nothing weird at all driving it. I was driving tonight and it felt good, also the start problem wasnt there.

possibly it was just a fluke. Can you describe the rough idle?

For first minute or so, it feels like the rpms are too low and there is slight vibration, shaking, then second exhaust pipe opens up (there is a valve that if car is not warmed up will only utilize right muffler, until warm or rpm go up) and everything is good. I found that out on the cold morning when I started the car and went to get something from the trunk, and I only saw that right muffler was on, and wondered why the left one wasnt. Couple minutes later it was on when the car was warmer.

Oh that's so not cool. Mine just starting doing this and I was wondering what it was. After driving a mile or so it goes away. I havent had any delayed starts yet but this sucks if its just a matter of time.

I hate to be the barer of bad news, but it is definitely the high pressure fuel pump, and get ready for a long wait. My car has been at the dealership for 7 weeks now, and still no eta on when the part will arrive. They said it is drivable, but that it will crank for a few secs(which seem like minutes) before it will start.
Does anyone think that you can lemon it for just that?
I do not know much about this, so any help would be greatly appreciated!

You would need to look up the lemon laws in Missouri (MO=missouri, right?)

It's not that easy to pull off. According to the law in CA, after 30 days you qualify, but again, it's not so easy. I am actively researching this right now... It look's like i would lose a few K to a lawyer, as well as the judgement, assuming it was in my favor. Call it 5K. That's on the border for me to absorb. Keep In mind that I persoanlly love the damn thing, so I'm willing to wait this out a bit longer (3.5 weeks so far.).

In Missouri you can lemon after 4 failed repairs or 30 business days out of service.

I don' think Lemon Law would apply. If they have a remedy, but it's taking longer due to parts shortage, then lemon law most likely won't work. If they are trying to fix it and time after time is not fixed, then yes....

That's what I initially hought as well, but when I read the letter of the law, there's seems to be ambiguity about that:

Form the Office of the A.G. Ca Website:

"....or (3) The Vehicle is out of service because of the repair of any number of problems by the manufacturer or its agents for a cumulative total of more than 30 days since delivery of the vehicle."

That seems to imply that the normal 4 times, safety etc. parameters do not apply when the car is out for that extended period of time...


what i have ascertained is that the average buyer/lessee isn't going to get any benefit from Lemoning the car... The simple truth is that most people, at 6 months into a lease or buy, simply haven't paid enough money into the car to make it worth it.

-Todd A.

In that case, looks like some would have grounds for Lemon Law, but I wonder how much time and money (on lawyers) one would have to spend to fight BMW. I hope they making affected people car payments or making some other kind of compensation.

My car also started with the longer crank times in the morning. The dealer checked the fuel pump and said it was OK. They installed the newest software version 25.02.00 to fix my complaint about slight bucking when cold. The software fixed the long cranking problem as well. They said this might be the cure in my case. So far after 3 days it starts almost immediatly each time

I noticed a few extra seconds of crank time on initial start up sporatically

This is fascinating reading, and very worrying. Thanks for everyone contributing.

I'm not sure if I've developed paranoia now, but I've noticed an uneven idle on cold starts. Since I have a manual, it means that I wait for it to settle until it warms up so I can avoid jumping around in 1st gear.

Any ideas? Or is this normal?

I have a March '07 build, and 3 times over last week I have had a 2-3 second startup.....each time with a warm engine.....I've got about 3200 miles.....the car normally roars to life immediately when i hit the start button.....

there is nothing else i've seen which indicates any problems with the car, at idle or at speed.....the only difference is the outside air temperature has gone up considerably in the last week here in Germany....previously its been in the 40's up to 60, but this week we were up in the mid 80's.....

i'll let the esteemed assembly know if the fuel pump goes out.....i've mentally prepared myself for it, but I hope it's not the case.....I've got to ship it back to the States in a few weeks, so it would be really bad timing.....
