Well, I guess you'd never done that with any dealer before, as a matter of fact, I just had a similar situation with my wife's CLK, and MB is giving us s brand new 09. Don't even have to pull out my top lawyers from the city to get the job done, cause everything is on record. If you have a strong case, I don't see why dealers or the manufacturers won't stand behind their products and honor their policies. Maybe you should spend sometime studying more about your rights than laughing.

I hear what you guys are saying but my sound that I am having is specificaly dealing with the area that I'm concentrating on.
I know there is a pretty big gap between the rod and clip, but the ticking isn't coming from there. When I posted the video where the ticking went away, the only thing that I did was address the part that I've been looking at all along and not the other part. I stopped at Ace Hardware to get some C clips. Let's see if my band-aid idea will work. I'm waiting for my engine compartment to cool down first. I will post my results afterwards but I don't know if I can get to it tonight anyway. Quote:

Ticking noise has just started a couple of days ago. I have late 07 build and the car has 6K on it. The noise is very annoying. There is a slight gap from the rod attachment next to the gold piece, its like 3-4mm but thats not the source of the noise. Sometimes you think the noise is coming from the engine head like a valve knocking but i'm not sure. The noise can be very misleading, being that it's not to loud and noticeable for right now.
Lets see what happens in a couple of week. My guess it will get louder and the noise can be traced easily. Also, the noise used to happen on the regular on cold start but now it does not go away. Changed the oil and noise is still there. Subscribed. |

Mine just started to rattle at 4500 miles. But, mine only does it upon start up when hot for a second or two. I can grab the rod that I can see from the top and rattle it by hand. BTW, don't try this when hot! I burned my finger on the manifold even after only running for 30 seconds!

The exhaust manifold there gets extremely hot. (I believe above 1000 degrees) I actually have a couple scars on my thumb from touching it 30-45 minutes after my car turned off.

^^^ I think I agree with a lot of that.
Shouldn't BMW be the ones fixing this? I know it may sound odd coming from me since I don't let anyone touch any of my car's, but this is truly their problem and their manufacturing or design screw up. The correct thing here is that BMW needs to address this issue. Things of this nature do not occur from downpipes or basic modifications like 99% of the people on this board. (In my opinion downpipes, PROcedes and everything I have seen around here are basic modifications)

Thanks for your tinkering here-it adds greatly to overall knowledge, though I confess I am still confused as to what the real problem is and what the real solution is. My guess is BMW doesn't yet have it figured out yet either.

I went to Home Depot today and picked up some more C clips since the others were to thick, but I'm a little hesitant with installing them only because there seems like there is something else that I'm overlooking. This is what I'm thinking today: What if BMW is correct about the wastegates not closing correctly. What if the wastegate rod loosened making the rod longer. If this were to happen then the pressure by the wastegates on the hole inside the exhaust pipe wouldn't be as strong (as when i first bought the car) and therefore the ticking could be happening by the wastegates clicking against the hole. If this is the case then all I need to do is adjust the rod by making the rod shorter. This would make the pressure on the wastegate hole greater and would minimize the ticking (if the ticking is really coming from there). Like I said, I'm constantly thinking about this and it sucks that I have to go to work because I want to get started on this ASAP, but the reality is that I do have a job and a family so it looks lilke I won't get started on all of my thoughts until this weekend.

If BMW still does not have a solution to your ticking problem and you really want to fix it, there's only one way to do it, which is take out both turbos, disassemble them, replace the factory rod with a shorter piece. I know our turbos are not particularly easy ones to disassemble since the exhaust manifolds and the turbines are one piece, but I always believe if someone can put them together, there's a way to seperate them. You can not bring this to a off the street shop, but a professional because as I said before, everything has to be spot on.

The rod is adjustable. See the threads on the rod? Also, give me some credit man. You're making me sound like I'm some kind of idiot or something. I guess I'm just the optimist here and you're the pessimist.

Thanks for doing all this Mr. 5. I can't understand why people are giving you a hard time, you obviously know what you are doing so where's the harm in that? Best of luck getting that noise fixed, keep us posted on your findings please!

Mr. 5 and AU is the ticking very constant and ALWAYS ONLY on engine decel or does it occur during other times as well. Either my DPs are hitting against a heat shield or my car has developed the same issue. I'm guess DPs though since I just installed them a few days ago.

Only at idle and decel.
For me, the ticking never happens at acceleration.
