The noise you have should be different then the noise on the 325/328/330 cars. I havent heard of any 335s having this problem.

Yura, I agree with flicks28, never heard about 335's engine doing the same thing as 328/325 engine. But look, it's better be safe than sorry: I would insist that the problem be fixed. If it is too loud, ticking noise I do not think it is normal.

BMW did a PUMA order on my cylinder head. The part is not here and it has been over a month. BMW advises the ticking noise does not harm the engine.

While waiting for the part, my rear window has stopped rolling itself up. So BMW replaced the window motor (car is only 15 months old and I never use the rear window). Next, the external bulb warning light to this BMW 2007 failed and all new sockets have been replaced.

BMW is not the company I thought it was and that I experienced with two prior 3 series.

Bottom line: ticking noise will get a "bleed" procedure. This will not work long term.

Recommend: Document document document your problems. Contact attorney if in shop for 3 repairs and the defect continues. File complaint with USDOT.

Solution that BMW should issue: Recall every model and update cylinder head.

[3rd3]

How has the repair worked for those of you who have had the repair? Any problems? Regrets or compliments regarding the proposed fix? I see one individual had the ticking noise in his BMW e90 repaired with a head, then it ran rough, and he claims it was repurchased. Otherwise, I have heard no positive comments about this repair.

[gbeckowski]

I just picked up our 2007 328xi from the dealer. It was in for the third time to address the ticking noise. The previous two times the bleed procedure was performed and the noise returned after a few days. It continues on a regular basis. My experience has shown the noise to be independent of temperature but is related to the distance I drive per trip. It definitely happens when I am driving a couple miles at a time.

This time the dealer did not hear the ticking noise so they did not do anything. I was told to call corporate customer service. Customer service instructed me to take it to another dealer to get a second opinion before they would send out a regional engineer. I think I need to log each ticking occurrence from now.

Coincidentally, the other items the 328 was in for were the same as 3rd3's, that is, stuck rear window (regulator replaced) and a defective lamp socket.

So I got a call from my dealer letting me know that my cylinder head is in and waiting to be installed on my car I have to say that was fast, as they only placed the order last week. Anyways, the car is going into the dealer first thing in the morning on Thursday I will give an update of what happens after, hopefully all good news

[3rd3]

gbeckowski:

If you have a video camera . . . I know this may be a pain, but, document the noise, the VIN, the date, and the mileage on the car.

Also, please be advised that your car has now been subject to repair and the defect continues. This may qualify your vehicle as a lemon in your state. I suggest contacting a lemon law attorney immediately. BMW is playing fast and loose with this issue...Maybe a few cases of paying for the vehicle to be repurchased, the plaintiff's fees, their defense fees to successful plaintiff/owners will allow BMW to recall the defective cylinder heads.

I now also have an oil sensor that refuses to tell me the oil level in my vehicle (regardless of how long it has been operated). All my friends and family say "wow that thing is definitely a lemon." I don't think a jury will find any differently...we'll see!

And don't get any hopes up on Reps, Customer (lack of) Care at BMW NA LLC. They have some amorphous "market team" who will claim the vehicle is normal. I suggest avoiding all of this and filing suit if you can under the laws of PA.

So I finally got my car back Friday evening after being at the dealer for 2 days. Looks like the tech did a good job of making sure everything was connected properly after replacing the cylinder head. I haven't had a chance to drive it much after, but the drive back home from the dealer went well. I obviously did not hear any ticking sound at that time, as the engine was already warm when I picked it up (road test).

One thing I noticed, was that the ride felt a little smoother and quiet. Not sure if it was just me, but it just felt a lot better.

Anyhow, I will post some updates here once I start driving around more.

The good thing about this was it looks like I got an oil change with that, as well as a coolant flush. I am hoping they put new fluids in there

The bill of material compared to other members that had it done looks different. That might be because this was a canadian dealer, but here it is:

I think I have the same issues as mentioned above on my 08 E92 328i. I have a very noticable engine knocking noise when I am next to a wall.

[mikeokimster]

I went to the deaership today to have them check this out. I discussed everything about the process on getting the HLA noise to dissapate adn suprised the SA. There was no trouble and he had one of the techs do the 5 step bleed process.

[Fortyb]

My car with 5400 miles on it was having that tapping sound also but only when it was cold. But friday i changed the oil and put in Mobil1 5w 30 and havent moved the car until this morning and normaly i would here the tapping after the car warmed up but this time as cold as it was this morning (26F) it was a nice smooth idle with no tapping. That's just day one will check again tommorrow maybe it's the castrol . Have you changed your oil yet?

I have not changed my oil yet. I did however get the bleeding done. The SA advised that driving the car harder will aleviate the noise from the HLA's.

It doesnt have anything to do with the oil. The ticking will be back.

On a side note, I always use 0w40 when using Mobile 1 and most people do the same with Mobil 1. With Castol it is 5w30.

[Fortyb]

Do you use 0W40 on your 325i also? I know 0W40 is good for turbo charged cars but i'm not sure for NA cars. As far as the ticking i'm on day two with no ticking and i left it out in the cold. It use to tick everyday, but i'm sure you may be right it might be back but then again it might not time will tell.

Wow. I finally found a thread that talks about the problem I've been having with my 2007 335i.. The engine ticking sound is definitely not normal, I remembered, first time I got the car, I left it running accidentally while i was at a restaurant eating lunch. It was that quiet, i didn't know the car was on. Now, it sounds like a diesel engine..quite annoying at a stop sign when you hear it. I think it made that sound around 7000 miles, now at 20000, it still there. Car is at dealer for wastegate rattling servicing, I should have them take a look at that noise as well..

The bleed process is usually a temporary thing and will eventually come back. How many miles are you putting on this car/day? If it does not tick a lot, I would not worry about it right away. If you notice the sound coming more often than before, it then might be a good time to get it looked at.

Yea, I think that is a good idea. There might be a chance they will hear it and it will save you many more trips in the future

Just a general update on my situation:

I have now been driving my car with the new (revised) cylinder head for a couple of days. During those days, there hasn't been any ticking noise I was able to try it out on short drives on cold days and everything was running well. Will keep you guy posted on anything new that comes up!

[new2u]

I got the cylinder replacement done about 3 weeks ago, and I could hear metal ticking noise even when the lot boy was driving out my car from the dealer's parking lot.
I was like wtf and went in to the service department right away. A technician came out and told me to drive the car for a full tank of gas to allow new parts to settle down. (bs, but I decided to try that anyways..)

Now I'll be going back to the dealer tomorrow to fix the problem.
Ticking noise is louder when the gear is in "D" or "R". And it doesn't even go away after the engine got heated.

Something must be terribly wrong....

So my advice is... go to a dealer who've done this a lot and know what they are doing..

Same here. It has been almost 4 months since mine vehicle got the cylinder head "Revised" replaced & has been doing very well. I'm happy with it

[new2u]

Update to my last post:
Dealer found exhaust leak on both banks. They replaced both exhaust manifolds and replaced all exhaust gaskets. Good news is that now the ticking noise is gone(I just got my car back today, so I would need few extra days to be 100% sure. )

[typeszh]

My car is in for the third time. I had to call BMW corporate, hopefully something will be done.

Edit: Finally they are going to try the head replacement. THANK YOU BMW CORP

Edit2: Got the car back I still hear a slight whine or tick under 1.5k but not as severe. I will continue to monitor it and my MPG has improved so far.
