I guess my turbo could be running hotter than normal, but then my engine coolant temperature is normal, if the two are related. I guess there's not much I can do but keep an eye on it for now, I figure there's no point in going to the dealer yet.

I think mine has the same thing but not too sure after looking at your picture again. Mine has a 1" section of smooth plastic that almost looks like the heat altered the rough texture of the normal plastic but again I'm not too sure about this. It looks like a very minor problem if it's even a problem.

That's exactly what it is. It's a small patch of smooth plastic where the rest is rough all around it. As far as I can tell that patch is smooth because the very topmost layer of plastic has melted.

Like I said, it's nothing to panic about, I'm just keeping an eye on it for now.

I wonder if that is a manufacturing flaw with the box and just happens to be where it is and has nothing to do with the car or the heat of your engine at all, it may have been like that when installed. I will look at mine I am on a short weekend trip to Austin to break in the car, oh, got about 38.3mpg leaving Houston yesterday.

It this on the top of box, and could you just replace the top.

I thought this too. It may be normal.

[maswastage]

Just an update- I've been keeping an eye on this, and as far as I can tell it hasn't been getting any worse. What's more confusing is that it doesn't even seem to be getting hot.

Last night I took the car out for a round of spirited driving, and immediately after parking I opened up the hood and placed my hand in between the airbox and turbo, and while it was warm, it certainly wasn't hot enough to melt plastic.

I even touched my hand up against the spot of melted plastic and it felt cool to the touch- and this less than a minute after driving relatively hard. So now I don't know...

[HoustonScott]

Checked mine nothing there. My guess is that was there when installed. How it got there in the manufacturing process no one knows...

[Nalod]

could the box have been taken off and touched the turbo, or was placed on it and it melted just a bit?

Drive morry..worry less. This isn't a big deal and is probably nothing.

Their testing process goes like this..."Hurray it starts! Lets start mass producing them right away!"

this going to happen to every single 335d out there.....

Not really. BMW is very good about monitoring before production, and his 335i is a 2010, probably not even a real issue. Especially since he said he had also checked it and felt the temperature himself.

However, if you'd like you can explain the situation to a BMW mech, WITHOUT letting them look at it, er go avoiding the ridiculous fee of them inspecting the car to conclude that nothing is wrong with it

Hi everyone. Please check my post on this site.

I think I have a more serious problem at the same part of the motor. The bigger turbo stopped working three times in 18 months. When it repeated for the fourth time I sued BMW here in Turkey.

Additionally the air pipes running close to the turbos are blown lately and the small turbo ceased working. My car is 80k km right now. I think, if you drive the car fast enough on highways, where allowed, there is a possibility that it also happens to you. Or, maybe, mine is just a lemon.

I am pretty sure that it will happen again for many more times. You do not need to worry if you do not drive hard enough.

I don't have much technical knowledge, so that is all I can tell about it.

Fuel consumption: 12.5 l/100km, 335d, 2007, no modifications.

1. problem occured in 2 months
2. 8 months
3. 19 months
4. 24 months

that look bad

Wow, this sounds like trouble in 335d paradise...the N54 HPFP sounds like nothing compared to this.

Yep the sequential setup is complicated. They're not perfect. One thing to remember is that the HPFP problem on the 335i is predom. based out of the U.S. and not worldwide.

[HoustonScott]

This guy from Turkey is the only person with a problem on the 335d. There are allot of those cars on the road all over the world, and this one failure. My gut is that what ever is wrong is causing the failure and what causes it has not been identified and fixed. Not worried at all....

Update on that turbo issue? Last post from Turkey was half a year ago.

It is on the courts now. My lawyer told me it can take up to one year and the success is not guaranteed. He said courts are reluctant to decide against big companies like BMW. So I am waiting for now.

I searched the net for some evidence but there is not many cars with the same problem so I think it is something special of my car. I think some parts there at the motor can't handle the high forces of turbos or the 286 PS and 580 nm or whatever (my amateur opinion).

What I will try to do is to force them to an agreement to change the car with minimal financial contribution of me.

I think it can happen because of driving style. I am revving the car a lot on the highway and the problem happens mostly after 30 km of fast driving to office.

They do not know exactly why that happens, they just change the part and give the car back. But I think this can be dangerous if it happens while you try to overtake a car on a two line country road. If there is a car coming from the other way, you can be in real trouble then. Who can take that risk?

[crazyniz]

Driving style may come in to it, but at the end of the day BMW have designed a 286bhp 3 litre twin turbo car...it should within reason be able to handle "spirited" driving.

stick to your guns chetuo, see it through.

The sames happened to my 335d after 30k miles.

and another member on the forums "terza" has suffered 3 times.

so the cases are mounting up.......

[Ron1n]

If by mounting up (after 3 model years), you mean like 4 cases, you're right.....that's definitely on the same scale as the HPFP failures.

I didn't understand what you mean but it happened to me just after two months. And it is a repeating porblem. The vacuum pipes are also in risk and blown at least two times. There is also the oil leakage which posted by some users on this forum.

The cars are very expensive here in Turkey. I paid 94k Euro and waited for 5 months but every six month or so it drives like a Fiat Panda. So, for me, it is a serious problem. And dangerous too...

There is at least three person on this forum who had the same problem. I also asked friends form Germany and waiting for an answer. I am told that people there also experienced problems like that. If I can find a case won against BMW at European courts or somewhere else I can use it here in Turkey to win my case.

Except that problem the car is fabulous and I love my car very much. But my life is worth more than a car and I feel at risk while driving it.

What do you plan to do?
