No that noise is not normal. Why does my car not make it? If it's still doing it then you got bad new parts, or they replaced the wrong ones. The only time this or a lifter tick should happen is if your car sat for a long period of time - like weeks. Find a different dealer.

Just asking if this is something to worry about.I just bought a 13 p31 car with 25k miles on it and it makes a almost knock noise on cold start up and goes away completely in 2 seconds right after start up.
It almost sounds like a pulley or tentioner from the out side and slight knock for a split second from the inside.
The car will also do it after a 10-15 min cool down and start up again.
I just had the dealer change the oil and that did nothing to help.is this normal or something to worry about?

Renntech carbon air box
carbonio carbon python intakes
Kleemann cam
kleemann tuning
kleemann headers
82MM mb tb
supersprint mid section
supersprint resonator
c63 mufflers

EDIT: Never mind. I thought all those mods were to your C63. Still doesn't sound right but as long as you have it documented that you complained and they told you no problem, you should be good to go even if it ends up failing at some point.

For many manufacturers/dealers normal = yeah, we know it ain't right, and we know a lot of them do it, but we don't know how to fix it, so keep driving because we are confident that this problem that we don't know the cause of is probably not going to leave you stranded anywhere.

People that also have or had this issue at start up were your cars development sls engines or the normal pistons and what oil are you guys using?
The first thing I did was a fresh oil change with 5ww 40 mb 229 oil at the dealer and that did not fix it.
Maybe 0w40 on next oil change?

That ain't right and I predict the dealer will blame one of these parts:
180mm pulley
Renntech carbon air box
carbonio carbon python intakes
Kleemann cam
kleemann tuning
kleemann headers
82MM mb tb
supersprint mid section
supersprint resonator
c63 mufflers

None of these start up issues have anything to do with rods or pistons. No difference between normal engines or P31 engines with the SLS internals.

Just spend $9k to have all cam lifters (32), cam adjusters (4), and camshafts (4) replaced out of warranty with 55k miles. one lifter had a hold in middle and some cam damaged. Decided to changed out all new parts from 2012 SLS 63. This is a known problem for 08-11 especially with the older lifters. There was a bulletin on it too....

Just got back from the dealer and had 2 techs listen while I started her.now the car was fully warmed up and it made a very slight rattle on 2 back to back starts and I was expecting them to say its normal but both said it needs to be worked on and that noise is 100% not normal
They said on a true cold start they are cranky but not normal for what my car is doing.
Car is going in on Wed to stay over night so they can hear the worst of it on a true cold start.

After listening to it a bunch of times it sounds like a rod or crank piston issue.they also said cam tentioners won't make noise after a 2 min cool down they need 3 hours to drain the oil.
I have row intakes will that be an issue if I need a motor

Very doubtful a bad rod would not just knock on start up static revving you would be able to hear a constant knock increasing with rev increase think about it not plausible a bad rod is always bad not just start up and if you listen with a stethoscope its top end noise but please let us know what the end result is I think they just have no idea really and no row airbox is a stock mb part

After going back and forth and explaining that I just dropped 60 grand on my car and I'm not happy at all with it they are changing all 4 cam adjusters.
I should have the car back next week.

Lol dude I guess you don't have much time dealing with the dealer.they have had my car for over a week now and still say they can't replicate the issue and said its normal.

Just an update the dealer had my car for about 2 weeks the first go and changed all 4 cam adjusters.
Got the car back and it still did it hot or cold start.the dealer has had my car for almost another 2 weeks and going back and forth with Mercedes in Germany and confirmed its not a normal noise and they are requesting detail logs and video to send to mb in Germany
I will update as soon as I get more details

Update!
Whole top end was redone
New 4 cam adjusters
Cam chain tentioners
All new valves and lifters bothe sides
Bore and scooped the engine with camera to see if any damage.
Oil pressure valves etc
The master tech was German and said he treated my car like it was his own.
Car idles like a Toyota Camry and you can't hear any lifters with the hood shut.

They did both sides because u need to wait 4 hours for all the oil to drain and its very time consuming to pin point witch one is bad and most likely from the same batch as the bad one so all were done.
After they went back and forth with Germany sending videos and audio of the valves they agreed to do everything.
Most dealers will say the noise is normal but I'm **** about my cars and got lucky the master tech was on my side.

Yes the can adjusters were done a few weeks ago but my car had 2 issues.after we did the adjusters I felt that the car had a slightly louder valve train noise then its supposed to and the master tech agreed.

So far so good.I'm uploading a video of a cold start(20 degrees) now there is a very and I mean very faint valve tic and it goes away after 2 min but all you can hear are the injectors working and its way smoother in person.
The video makes it sound so much louder
