W212 E63 AMG Facelift
FAFFAA0A-1B06-4444-8EE9-C43A9D5C2AF0.jpeg Hi all,

I’m new here, but hoping I can get more involved now I have an e63!
I picked up a 2013 facelift w212 around a month ago, loved every minute of it. It has had a few tweaks like cats and resonators removed and some mapping and is currently at around 750bhp.

Anyway onto my issue...the car has full MB service history and no service was due but the garage I bought it from performed their own service on it which was filters, oil change and air filters now I have already had to replace the air intakes as these had completely collapsed and got sucked right upto the filter I was pulling them out like a clown would keep pulling hanky’s out of his pocket. I notice this more so wen I pull to a stop off gas completely, a fair bit of smoke sometimes can be seen coming from the rear, more so if I have it in sport or sport + I would say, it is strong smelling. I managed to get in touch with the previous owner and he said it had never done that with him so my concern is that it either has too much of or the wrong oil in from this last service?

Does any one have any ideas what it could be? I was going to ring MB today to get it booked in for full oil and filter change ASAP.

I am grateful for any help on this, it’s my first Mercedes and am looking to learn/expand my knowledge along the way.

Cheers, Scott.
 
Welcome Scott.

The car should warn you if the oil level is too high, does your car have a dipstick to check or does it rely on the sensor in the sump? If the latter then what does the oil level check say?

is it possibly over-fuelling? It depends how well the map has been written and applied, as you notice it more is Sports modes when the fuel map may be altering the injection timing etc it is a possible cause. Without some of the catalysts you may well get a stronger smell of fuel combustion products from the exhaust?

hi can not help with your problem but welcome to the forum thats a cute dog you got there
 
"... it is strong smelling."

Of what? Petrol? Burnt oil? Coolant?

My thoughts too. - Does it get better or worse when the engine (and exhaust) are hot?

It's probably been mapped to add fuel on the over-run, officially to keep the bore temperatures done... but unofficially to make it pop and bang. - If the exhaust isn't hot enough to ignite it, then you just get fuel coming out the exhaust.
(The "race cars add fuel on the over-run to cool the bores" is something I only recently learnt. I assume that's what the Sport+ map is doing too.)

Hi DSM,

Just checked the dipstick, it is high on that but no perfectly leve ground in any close proximity. Is there a secret menu or anything do you know of? I can only find info on older versions how to get to this. The ok and phone button don’t work.

I thought that at first and sort of ignored it for a while then I just got more worried hence me speaking to the previous owner who had all the work done and he said it had never smoked which made me dismiss any mapping and put it down to the service.

Yes I agree it would smell any way and the previous owner said the same thing but he was worried when I mentioned the smoke.

Hi Pobody,

See my reply to DSM.

Also, it still does do it in comfort mode. It’s usually I notice when warm and I’ve given it some.
My biggest concern is the previous owner was shocked when I told him.

Could too much oil cause the smoke and the smell is the fuel which is in the same cloud of smoke? I would make a video if I could but do not want to drive it if possible until I know. Especially if it is too much oil as I’ve been driving it a month. The smoke wasn’t always very aparent to me though as the tints are very dark in the back.
 
The snag you are going to run into taking the car into an MB dealership is that its been modified. The only people who really know what to expect as "normal " are the company who modded the car or whoever serviced it on a regular basis.
You would need to ask the previous owner about who serviced /modded the car. Bear in mind also that modding a car has implications for long term reliability and the previous owner may have had some inklings that things were about to go pear shaped before he sold it. If you are concerned that the oil level is too high you could try reducing it by using one of the many oil extractors available on the market that suck the oil out through the dip stick. A good working level to aim for would be 3/4 of the way between the hot /cold ---full/fill marks on the dipstick when the engine is warmed up. Another thought is that the garage that just serviced the car used the wrong oil--- iirc AMG engines are very fussy about the type of oil that's put in them.
 
So, following grober's advice, get an oil and filter change, ensure it is the correct oil filled as stated to 3/4 and talk to whoever modified the car.

I hear what you are saying. I know the MB was Europa in Sheffield that did all the servicing for it so I can take it back there no problems. I always thought the oil should be checked when cold as it settled and an accurate reading could be achieved?
I will speak to the garage where I got it from to see if they can find out what oil.

Oil can be checked hot or cold, most dipsticks have a hot or cold marking. If the level is at the maximum when cold then it will be over the maximum when at operating temperature hence the advice to fill to 3/4 on cold.

I have parked it level and will check shortly and report back

It’s hard to tell in my opinion as it isn’t consistently on the stick... this was from a couple of try’s.

I'd have preferred it staying with MB unless I knew the garage was using OEM parts.
Usually non specialists will just ring their local supplier and get the "parts" delivered.

I was thinking exact same as grober has pointed out when I was reading this.

MB haven't done all the servicing now though and if you take it back to them with non OEM parts fitted then that is their out clause.

As has been stated an oil/filter change would be very adviseable using OEM parts.

Me too, but I didn’t get it serviced, they just did it as I guess they service every car that comes in, they do have Ferrari’s and all high end cars so until now I had no reason to be worried about it. I have requested from them the amounts used and type of oil.
I just meant I would take it back to Europa to get the proper oil and filters etc done as they know the car and can use The right stuff.

What is your take on the dip stick readings above?
 
I have since found out the oil used is carlube 5w30 fully synthetic...
Which cheaper than MB Mobil 1 and could be the cause of my problem.

Possibly the cheapest and nastiest oil out there and the wrong grade. Does it meet MB 229.5 spec?

I would get MB spec oil from MB Newcastle delivered (£54 for 10 litres inc sump plug washer and oil filter)
The garage that changed your oil should have used 229.5 spec 5w/40 fully synthetic.
Genuine Mercedes-Benz Petrol/Diesel "A" Service Engine Oil and Filter Kit NEW | eBay

5w/30 is recommended for diesel engines.
I think the oil is the cause of your problem. Get it changed ASAP.


Edit...... Thought you has a CL500 for some reason.
I'd use Mobil1 0w/40 fully synthetic.
