Unhappy Wastegate Gate

I got my 2007 E93 with 84K miles about a month ago and immediately heard the wategate rattle. I knew what it was because I joined this forum and read all about it. Why wouldn't the previous owner fix it I wonder? It's loud, annoying, and embarrassing.

Last week I took the car back to Carmax to have them fix it.

The service guy called several days in a row saying they couldn't determine conclusively that it was the wastegate. On the third day I was annoyed and insisted that they do more than listen for the noise. The next day he called to tell me they were sending the car to a BMW shop for them to look at it.

Today I'm told that the BMW shop will be re-flashing the ECU. Then Carmax will inspect it to see if its fixed. If so, I'll get the car back tomorrow.

Are they doing this so they don't have to pay for parts since the BMW warranty won't cover it? Should I expect it to work? What should I do if it doesn't work?

Anyone have any experience with this?

If your warranty is like mine, you can take it anywhere you please. I don't know how high your copay is, but I doubt it would be high enough to deter me from taking it to the best indy that I know of. (My copay is waived if I take it directly to CarMax.) In general, I trust BMW specialist indys more than dealership service, and that is also based on personal accounts of people I've met. Try the bimrs.org site if I typed that out right, to start getting a few indy candidates in your area.

Since I was still in the first 30 days there was no copay if I took it to CarMax. Plus I thought I'd let them have a crack at making it right.

Thanks for the link since I prefer Indy's as well. I know it's $50 less if I go to CarMax in the future but that's no big deal. Plus I'll need to find out what their repair approval process is and the easiest way to get a loaner.

Reprogramming should have been done a long time ago but it might help the wastegate rattle. When do you hear wastegate rattle? Typically it should just be when cold and once warm it should not be audible. If it is it is time to get under the car on a lift engine running with heavy gloves on and check the heat shields on the cats too and shake anything loose. Since the wastegate is integral with the turbo you might repeat might be able to get your hand or a tool up there to feel or even see if the wastegate is rattling.

Please post how this goes. BMW did do reprogramming on the DME to eliminate many issues with the engine in general and one of those was a change on the wastegate algorithm but that should have been in 2010...

It rattles on cold starts. Sometimes it's louder than other times. Sometimes it rattles for a few seconds, sometimes for a few minutes. But its so loud that I can't imagine the previous owner tolerating it and not getting it fixed. It's the first thing I noticed the morning after I bought the car. Makes me wonder how long it's been happening and whether a change in the software will work.

I watched a YouTube video that showed a guy disconnected vacuum hoses as a way to test the noise. I tried it and the rattle got quieter with the hose disconnected. I'll post it if I can find it.

I'm hoping to hear good news in the morning.

I got a call this morning and was told that it was back from the BMW dealer. They did the reflash on the ECM? ECU? He says "there's still a slight rattle with the roller bearings but all 335's have the same rattle." So they went out to their lot and started up another 335 and heard the same rattle. So, that means they are satisfied with their work. I'm skeptical of course.

They are really nice guys and I don't want to give them a hard time. But I'm pretty sure I'm not going to be satisfied if I hear the slightest rattle.

My bottom line question is should I hear a wastegate-related rattle AT ALL after the reflash? If not, then does that mean they need to start replacing some parts?

So, I have the car back. The rattle is still there, but this morning it only lasted for about a minute and disappeared almost entirely. I'm going to test it for a few more days just to make sure, but I think I'll be taking it back to insist on new parts.

What an excellent test! Statistically, I believe that yields a 50% confidence level.

Are you OK with that? Is CARFAX?

They are perfectly fine with it. I've heard them say several times that all 335's have that problem. And I tell them that's because the owners tolerate it and don't get it fixed.

Here is the official language on the repair document:

Concern: Customers says there is a wastegate rattle upon cold start.

Cause: Verified concern. Found fault stored for charge pressure below spec. Found TSB SI B01 01 12. Inspected turbochargers per TSB. Upon inspection found turbocharger wastegate clanking. Out of extended warranty by 3k miles. Rec update s/w levels to start.

Correction: Recommend sublet to dealer for ECM software update per TSB. If update does not rectify cold start wastegate clank we may need to replace wastegates actuators/turbochargers. Dependent if low charge pressure fault remains.

After having the car back fo a couple of weeks I've discovered two things. The software update has improved the shifting significantly. The transmission feels wonderful and I can move up and down the gears much more smoothly. No more jerking between first and second.

More significantly, the wastegate rattle remains. BUT, it lasts for no more than 60 seconds where it would typically last for 2 to 3 minutes. When it is rattling, the noise is just as loud as it used to be.

I've decided to take it back soon to insist on the proper repair to eliminate the noise for good.

For anyone interested, here is Service Bulletin TSB SI B011 13 07. It covers the diagnosis and repair procedure for "N54 Distinct Clanking Noise from Turbocharger Area" in the following models E90, E92 and E93 (3 Series) 335i and 335xi, E60 and E61 (5 Series) 535i and 535xi.

I'm unable to find TSB SI B01 01 12.

Last week I found time in my schedule to take the car back to Carmax to get the wastegate rattle resolved once and for all. The big motivator was that I had begun getting the yellow half engine light when I accelerated on the highway.

When it was in the shop the first time all they did was the reprogramming. The car seemed to run better, but the rattle wasn't fixed. This time they changed a solenoid, some hoses, and the reservoir. That took about a week. Then, after testing the car they decided that the turbos needed to be replaced. Yay!

It's taken a few days to hear back, but I have just been told that the warranty company has approved the new turbos and the parts are being shipped now. So, I figure I'll be driving the loner Camry for at least another week.

Still, I consider it a victory since I had to continually insist that all the repairs they were attempting would not be satisfactory.

Carmax will not know how to work on it and they do not have the BMW tools to even see the BMW specific codes. Since your car is an 07 it most likely has all gen1 turbo parts. For sure, all the vacuum lines need to be replaced. One vacuum leak on the turbo side (from the vacuum port by the oil filter) can give you this issue, but it probably needs the turbos replaced like most other 07/08 cars.

Now that they've fiddled around with it for a week, I believe they are sending it out to the large BMW dealer in the area to actually replace the turbos.
