335i owners check in! (turbo/wastegate rattle)

[bimmerfixr]

Wondering how many 335i owners/drivers are having a problem with turbo/wastegate rattle noises that they absolutely can't live with?

[Paperbill]

not sure about the noises, but I had to have both replaced at around 20,000 miles

[TeaRoy]

Had to have them replaced?? May I ask why? I get something was wrong...but could you elaborate? Thanks.

[Paperbill]

engine light came on, loss of power, that was all. Spent a week trying to fix it

'07, 335i coup, 15k miles. I had my 335i towed in May '08 after the fuel pump crapped out.When I got it back , I noticed waste gate rattle around 3500 R.P.M when releasing gas pedal. They had flashed the new software update. I took the car back to dealer and after 10 days, they replaced waste gate actuator and did some software tuning. When I got the car back, the noise was more pronounced when accelerating.
Took it back to dealer the second time, and after 3 days working on it, gave it back saying the problem cant be fixed !! They have a open puma case with BMW and would notify me when a permanent fix was available. Now the waste gate rattle is noise is even more pronounced.

Anybody heard this story from a dealer ? or recommend any solution. I saw somebody mention that they has their turbo replaced ?

i have a '08 335xi. is this something im most likely going to run into later on in the mileage? i only have 1,500 miles right now. am i looking at any repairs coming up soon that a lot of other ppl encountered?

[derbim]

look below for my post entitled "heads up....."

This "issue" just started occurring on my 09 335i coupe that just turned up about 2,500 miles on the clock. Two days ago I heard it for the first time. It appears at around 1500 - 1800 RPM and is much more noticeable on deceleration. I went for a road test with my local BMW dealership's shop foreman and he seems to think it is a turbo wastegate noise but wants me to leave the vehicle there so they can diagnose/repair, but I'm not sure if I want to open that can of worms and possibly make things worse. After all, it isn't causing any problems or power loss (at least not that I'm aware of).

I had the waste gate actuator issue last fall. My dealership had their ace technicians do the replacement, and the job was done flawlessly.

I could not live with the noise, nor should anyone, especially if you are still under warranty. Nothing worse than a Bimmer going down the road sounding like there's a bunch of empty beer cans rattling under the hood.

Waste gate rattle is fixed. I guess I was one of the first. See my earlier post "heads up". Because it was such a new problem, dealer and BMWNA tried several different fixes. Eventually had the gates replaced, but the real issue appeared to be software related. After about 3 upgrades, problem is fixed. It was not crimped hoses to the actuators, nor was it the actuators themselves. I have had continuing problems with misfires, and again, software was the fix. Evidently there is a problem with earlier versions, causing, as I understand it, math errors in the embedded strings, leading to a misfire after so many miles. A new software upgrade came out in early April, and now it runs better than ever.

I just had an upgrade but the noise is back...along with brake squeal which they fixed before

Is the brake squeal on acceleration or when the brakes are applied? I recently started hearing some squealing when I apply the brakes esp. when almost coming to a stop. It doesn't happen often enough to bother me and I am inclined to assume it is due to residue on the brakes or some material in the pads themselves, but either way it is probably transient.

Stopping squeal is normal and can be cured with a few hard braking attempts.

This squeal, like many complain, is a squeal while accelerating and at low speeds. It sounds terrible and isn't a normal squeal from dirty or glazed rotors.

Dropped mine off today at my BMW dealership for diagnosis/repair of the noise. We'll see how it goes...

how did it go?

[joec1101]

They had the car for a few days and finally diagnosed it as an oil line rattling against something else in the engine compartment. Once they secured the line, the noise went away. So far so good...

After everything I read and having identical symptoms as others with the problem, I was damn sure that's what it was. Guess not....

I am a little peeved at the dealer, though. When I got the car back, I noticed (not until I got home of course) there is now a gash in the left front wheel as if someone ran a cart or tool or something into it and also the door sills are now scuffed and scratched from the shop techs dragging their work boots across the surfaces.

Its going to happen, I see the scuff marks on my car on the bottom door sill from me and the wife getting in and out.

Dude, if you are bothered by this what will you do when you get the 1st ding or scratch. It is a car and cars don't stay new forever.

i have been driving my 335xi since december, and i have to say this car makes some wierd noises for sure. its at 36000km's (22000 miles)

the one that i noticed the most was when the car was started below -15 celsius (+5 fahrenheit) the car would start normally and idle very high, then after a while a very loud "Ping" would come from the exhaust. i could only guess a wastegate or misfiring issue.

another noise is when i start the car, before it reaches low idle it makes a ticking noise. once low idle is reached it goes away. not sure if this is normal.

any imput?

another strange noise that im am very sure is nothing to worry about but i still think is wierd, is when your in the car with no radio or any noise. there is a faint beeping that kind of sounds like it is coming from the back seat, but i have never been able to locate the source. maybe i should make a hat of tin foil for this one? XD

sorry if i thread jacked a littlebit, but i didn't feel the need to start a new thread for this one

I took my 07 335i coupe to the shop more than a week ago. I was told every day that it should be ready by "tomorrow lunch time".. it took them 8 days to finally say you can come and pick up your car. I signed the paper work than fired the engine and noise is worst than before!!

What can you do? I told them no way I take the car before they fix it... they were sorry and said they'll fix it....
Its in Dallas and the shop is BMW of Dallas.
Anybody experience with them??

Turbo cars have things you aren't used to hearing.

The idle is normal in cold conditions. The "ping" you hear is the exhaust valve that opens and closes to reduce noise when on the freeway.

Ticking is normal, usually injector noises.

can something be wrong if i am running golf tee mod, zip tie the rubber tube?

No the car doesn't care if the exhaust is open it's just making it louder free'er. There really is nothing it can affect at the end of the line. Some back pressure might help turbo spooling, but I doubt anybody can tell...it opens under acceleration and closed while cruising simply to reduce noise.

I have the rattle noise on my 335 and it drives me crazy!!!!
I took it to the shop twice and after 10 days they claimed the "issue" solved. I took the car home and in couple of days I can hear it again in the morning. So my question is: Is there a permanent fix or I have to live with this (its an expensive car!!!!!!)>>>>> I don't want to and I hate it to high degree.
It was manufactured in 2007/April.. it might have something to do with it??
They changed both turbo and adjusted the wastegate 100 times...
I am wondering what else they could do this time.. or they are just not competent and I should go somewhere else!??
Any idea?
Thanks in advance,

Turbo cars make noises, but I'm starting to think I hear the exhaust valve and that is making more noise than the waste gate.
