Well the vibration still is there, slightly better after engine out and new gasket to manifold.
In with the dealers next week to check it once and for all.
The guys a MB motors in Chester have been completely a joke to be honest. I have given them the benefit of the doubt but its truely amazing how crap the service has been and communication and effort. Not to mention the amount of collateral damage my car has sustained there.

Trim missing from interior vents.
V12 Bad on engine cover broken off.
Engine cover snapped.
Plastic under the engine comes in 3 parts, 2 parts where completely smashed up, new ones put on.
headlight washer gone, (probably not them that one)
Various pipes around engine lose not clipped on.

The car always comes back covered in crap.
I book it in for a 5 hour job and it takes 7 days.
Comes back not fixed and normally with other issues.
First time vibration still there, 2 weeks later with them i came back broken coil pack.
The could not find the source of the vibration even though its been in there garage for maybe a total of 12 weeks.

I've spent well over 4k and nothin improves. To cap it all off, i get to be the villian for ringing up and pestering them.
What mercedes dealer says its a 10 hour job. and it took them 8 days to fix.

Absolutley no clue, no effort and no expertise. Ive used them twice once with a radiator that was replaced 3 times before they notice there was 4 blades missing from the fan and it was hitting the engine and putting a whole in the radiator and the S600.
It only had a blown turbo that needed replacing, but it been hacked hammered and badly replaced, never worked properly since they put it in.
I look at the state of the bits i can see and think if they cant take off and put back the simple bits like the cover what the hell they done with the turbo and pipes.

Anyways, now since i picked it up from friday, bear in mind it was working fine 7 days ago apart from whoosing noise over 2k revs. Now its smoking.
Then smoking alot and engine management light comes on. Then it goes no smoke engine light off, then it comes on again.

Checked oil level thats ok and water level is unchanged and in the expansion tank the water is not contaminated.

It had new cats put in not oem but 400 cell cut and weld ones.
I touch the cats they are red hot.

Anyone know what the smoke could be and what mischief they might have done, dirty sensor etc.

"""""""""""To add to dieselman, the turbo has a high pressure oil feed coming into the top of the turbo (looking down from under the bonnet), there is a seal on the engine (I think copper, but cant rightly remember) and a copper seal on the turbo. On the underside, there is a low pressure return pipe, again copper seals at the turbo and a push fit into the crankcase. Any wear or ageing on these seals can lead to oil leaks. As mentioned, check your exhaust pipe and look for white smoke (oil leaking into the combustion chambers/exhaust manifold from within the turbo itself).

Firstly, verify if there is oil being burnt, if there isnt, check around the turbo by cleaning and dusting with chalk, and also on the cylinder head where the high pressure oil feeds out from and the crankcase where the low pressure return is.

The breather pipe as mentioned by dieselman tends to leak at the top of the cylinder head (a black circular seperator) and can also leak on the t-junction into the turbo air inlet pipe. You should hear a wheezing if there is a leak on this junction though. """""""""""



From another post. Sounds like my Clowns at MB MOTORS . Some seal bad put on.
You know everytime they have had my car i have had to pay for extra parts because they have broken, when taking them off or putting them on.
Ill have to scan the bills.

You must take the car away from these idiots. I have had dealings with MB Chester recently. They are a disgrace. Do yourself and your car favour and talk to the guys at PCS about your issues....don't worry about the distance, it will be for the best in the end.
 
Ive never touched a S600, but smoke, if you mean black exhaust smoke, engine managment lights, and whisting noises, suggest a boost leak somewhere after the AFM(s).

Boost leaks post AFM cause very rich mixtures, which would make the smoke.
Boost leasts on turbo cars make a audible whistle.
Bad AFM readings or the lamda sensor picking up super rich mixtures will cause the engine managment light to come on.

Its a discgrace that main dealers are like this.
 
I'd consider a formal complaint to MBUK.
 
Its the length of time they take aswell.
They said after 3 weeks of having the car its not the turbo or any pipes its the gear box. They are going to send it to an automatic specialist 2 miles from the unit to check it.
1 week later nothing so i rang cheshire autos and asked if MB motors had brought my car into check they said no, but they have brought 3 cars in last week to have stuff done. I thought what have you been doing for a week, i went took the car drove it to the auto specialist and they checked everything and said auto and torque converter are spot on. 30 mins it took me to do that. MB motors had it for 1 week and did nothing and no communication nothing just fobbing me off.
I just cant belive how bad its been to be honest.
 
"""""""""""To add to dieselman, As mentioned, check your exhaust pipe and look for white smoke (oil leaking into the combustion chambers/exhaust manifold from within the turbo itself).

Unless the basics of the internal combustion engine have drastically changed then "white smoke" is never indicative of oil.

Solid White= mainly water in combustion chamber or even transmission fluid .
Translucent white=water vapor typically on startup
Blue= always oil
Black= petrol

What color smoke are you seeing out of the tailpipe?
 
<P>Its white. No blue or black at all.</P>
<P>It somethimes alot sometimes not much. I am not driving the car as dont want to do damage to it. </P>
<P>I have checked the water level and its fine.</P>
<P>Considering its just had the engine out and turbo refitted etc i think its more likely they have not but something together right, going on past performance that prob 99% chance. Going dealer next week to see what they say. Like I said MB Motors in chester is unbelievably bad for a specialist. BEWARE.</P>

If the smoke from the tail pipe is white then it can be only two things:

1) Head gasket with water being drawn into the combustion chamber and turned to steam.

You state the water level is fine.
Have you checked your radiator fill reservoir to see if when the thermostat is open there are any "bubbles" cause by combustion gases enter the cooling system ?

2) Transmission vacuum modulator..
If the diaphragm in the modulator is damaged then transmission fluid will be sucked into the intake manifold.
The indication under certain engine loads is a thick white smoke from the tail pipe...
Check your trans fluid level..

Many shops overlook the transmission vacuum modulator as they are more focused on the engine...

Link below is to a USA site to give you an idea of what the part looks like.
It is a simple DIY if you have the ability to safely lift the car..

Turbo seal failure can also cause puffs of white smoke but not from the tail pipe

How the hell as the head gasket gone? I have checked only the overflow bottle level.
Also are the intercooler pipes supposed to be hot? As they are not!!!
 
Also i seem to have the same symptoms as the guy with the ML on this engine forum.

Reread my post....
I gave indications of what creates white smoke...
Either water or transmission fluid in the combustion chamber.
Never stated that you have a head gasket problem

Does your transmission shift hard?
Check your transmission fluid level and note the fluid color...
Loss of trans fluid could be a bad vacuum modulator..

Which intercooler pipes inlet or outlet?
Inlet will be noticeably hotter then the outlet..
Charge air temp is proportional to boost...

"I have noticed that my car blows some white smoke.
I have also noticed that when revved oil comes out of the rear exhaust.
I then put a piece of paper under the exhaust and hit the accelerator hard.
Oil was splattered over the paper, around the edges it was a little bluey."

You have to discern the actual color of the exhaust emission...
If the ML owner as above is getting oil then his smoke is not pure white...
More blue as he is seeing oil on a piece of paper.

You should be able to smell the difference in the smoke...
Water/headgasket will smell like steam..
Transmission fluid has a slightly sweeter smell..
Oil is more acrid...

Try the paper over the tail pipe and see if you get any oil residue...
If it is oil, then the smoke is bluish tinged and it creates another list of potential sources of the oil.

Thanks RBYCC,
Its blue tinge defo, and it does smell of sulphur.
Just had the AA guy say it defo blue tinge.
Amusing as the AA guy said lift up the bonnet all purposefully, like he was going to do something.
Looked at the V12, paused for 10 seconds.
Then said ill get the tow truck to come.

LOLOLOL.

The V12 scares most common men !!!
Possibilty if it is a slight blue tinge that it's post combustion oil...or oil entering the turbo...
Pre combustion oil is a noticeable blue emission...

The most difficlut part of owning a high performance Merc is finding a reliable mechanic..:thumb:
