Hi, since there are way more 55 AMG engine drivers in the W211 Forums, i would humble try to point you to my thread in the CL55 AMG Forums.

Can anyone tell me what ticking that is?

Sorry haven't meant to double-post at all. I just need some help/ideas.

EDIT: Here the Video if you dont want to follow the original link:

Sounds like idler pulley to me but what the hell do I know! I had that issue when I bought my car and changed it and it was gone. Look at the pulley when running and/or with it not running, see if you can move it back it and forth.

Mine sounds exactly the same. What oil filter are you using?

Crissus

Is that really producing that rhythmic "tick tick tick tick tick tick" sound?
I thought that would be more a grinding sound or "rattle" when the double idler goes...

Stock MB one.

Maybe it was a little difficult to hear that part of it when listening to a video but mine had a similar sound but was not really rhythmatic (is that a word?)...just noisy. Just check it, takes 2 minutes.

Pull off the super charger belt. Run the car. If it is still there spray a small amount of lube on each pulley. One at a time. That is how I found my noise.

my e55 sounds same, dk if there is something wrong or its normal

These motors are not quiet, and frankly, sound unpleasant at idle and low revs.
Most of the time, it's normal. My 06 makes the same sound as my previous 06. Completely normal.

I'd start with the lube process just to make sure nothing else more serious is going on. I'd also suggest the above and move forward accordingly.

Thanks for the Input. Just for your information, the ticking is only audible at:
0:51 up to 1:17 and for a couple of 2,3 seconds starting at 1:52

The rest is really the well known "unpleasant M113K" sound. Yes they do all sound like that (test-driven couple of em before buying this one).

What sstill bothers me though, is that you can only hear it from below the car or when kneeling sideways near the engine area. Also it annoys me when going into any Drive-ins like at Mcdonalds or else.
I first really thought that this would be a failed lifter, because of the frequency of the ticking, but the sound is not at all coming from above, neither from the front.

I'll check further this Weekend and post my finding here.
Again thanks for all input.

I haven't got 'this' sound. TBH it sounds pretty 'normal'.

I've got a high pitched ticking sound that comes from near the oil cap somewhere and is only present on cold starts for a little while. Noisy tappet FTL. Nothing serious, just a bit annoying.

The sound you hear in the wheel well from the lower motor I believe is the oil pump, from what I understand they are normally noisy.

Crissus

Yes and thats another point i forgot in my initial posting.
I heard from a guy in a german forums that repairs Mercedes and especially AMGs that he changed at least 5 oil-pump wheels and chains on the M113Kompressors because of various sounds they produced.
He said the chains lengthen themselves over time and start to make those sounds.

tsquare

I have never heard of oil pump failure on any M113 motor.

Maybe not the pump itself, but what he's talking about is the drive chain. The oil pump has it's own little chain right in front of the timing chains with its own tensioner that could be making noise.

Think I have the same tick. Having a mech look at it tomorrow. hopefully it something as easy as the idler pulley. I was told it was on its way out, scheduled to fix it, but maybe this it. I noticed a light chirp sometimes when taking off with any decent amount of gas. I then cleaned the pulley's just with a dry rag to get some dirt out. Also hit it with air can. Chirp went away it seems, but tick now. Hoping it is simple pulley.

I will hit it with some belt dressing or wd40 for a second to see it tick goes away? Also , see what mechanic says.

It definitely is louder when listening near drivers wheel well. not sure it is coming from pulley, just hoping. when listening though passenger wheel well, it sounds quiet but you can hear the tick coming through from drivers side

any other info welcome. Hoping it is not the start of lifters or internal parts.

Will post results tomorrow.

Ps. I saw maybe the oil pump suggestion but wouldn't that have been noisy/ticking the entire time I have the car? this definitely started today.

60nomad

Holy cr*p! I heard this same thing 2 days ago for the first time coming from the right rear wheel area (I think). It only did it when it shifted into second gear and when going slow, normal driving or even less then nprmal driving but not any other time. I kept making it repeat it by stopping and doing it again and again and 90% of the time I heard it. Is this the same thing you're talking about? If not then anyone have any ideas on what it could be?

Maybe I will take it out today for a little just to try it again. I put it away Wed. and haven't had time to use it and if I do not take it out today then I will not be able to do it again until later next week.

cobra101

well, your chirp is probably the infamous supercharger chirp. lots of info online. Many say it is normal and they have grown to love it. Mine just started and it seems annoying.

solutions I have heard: 1. small drops of stop squeak between the s/c pulley and pulley clutch behind it. 2. light 400 grade emory paper between the sc pulley/clutch. and of course either belt replace first and then sc clutch replacement (some have just fixed bearings on the sc as well)

my mech said my tick is not too much to worry about but could be the strat of lifters/valves. not sure, but it definetly just started and is much more noticeable in quite streets or garages. but then it pretty loud I think. not quite old merc diesel style but to me very noticeable. and certainly wasn't there 2 days ago

adianaty

Op, if it comes and goes it could be your AC compressor. It's hard to tell what sound you are talking about exactly, but try again with the AC completely off and see if you still hear it.

Well despite the tick coming from other side of idler, it seems to be an idler. When cleaning them it must fave gotten worse. I sprayed a very small amount of lithium grease on them and it started to go away and then return. I put a bit more lithium and item seems to be gone for now. New asp 3 piece islets on the way.

Hopefully this is a permanent fix. Will post update next week.

Crissus

I bought myself a stethoscope, and the ticking comes not from the top, but from the front bottom portion from the engine. I can hear it clearly when i put the stethoscope at the upper oilpan from below.

However chances are still that the sound of a broken idler transfers itself through the timingcase cover to the oilpan, where i placed the stethoscope.

As soon as the fixed SC pulley is ready, i will buy new ASP pulleys also, to make sure it isnt the pulleys.

Jimshorts

Possibly a header tick... had that in my car.

Crissus

Was it also only noticeable when the engine was warm?
Thats still the point i dont get. With cold engine no tick, with warm engine ticking starts.

Jimshorts

I did only notice it when the car was warm. I would hear it really well when driving next to cement barriers on the highway at low speeds. The ticking would come bouncing off of them, I do not recall it at an idle though.

Do you have after market headers on the car?

Crissus

I found a guy that has the exactly same ticking noise like i do on video... And his camera was able to capture it much better actually.
Listen below:

Crissus

Found two more and all have that sound in the background as it seems... LOL.
It really seems to be "normal" ??? I cant believe this...
Anyone here bought this car/car with 55K engine new? And can confirm its there from the beginning?
