Picked up an Edition 1 this past week. Just a couple of things I wanted to see if any of you were experiencing:
1. There's been a slight overflow of coolant out of the front reservoir when the car is up to operating temperature. I pulled off the cover over the reservoirs and could see some dried coolant around the area. It's not puddling under car - but I can smell it and see where it dries down the sides of the reservoir. Have been told by the tech that the SLS was known to do this at times - and that AMG overfills to a certain degree, the coolant and that it would eventually get to the proper level. I've never had a new properly functioning car do anything like this. To me it would seem the pressure release threshold of the cap may be too low. No overheating whatsoever on the temp gauge. Did have a "blue" coolant message briefly flash twice. Possibly it was the sensor sensing an overfilled condition vs an overheating condition. Thoughts?
2. There is a pesky vibration that appears to be coming form the crossbar area that only starts after about 2-3 minutes of driving when going over rough pavement or road imperfections. Sounds like a vibratory, resonating buzzing that must be resonating through the aluminum cross brace after some components get up to a certain temperature. Can't imagine what it could be.
For both - taking it in this week for them to evaluate.

I've racked up over 600 miles so far and all is well and I am very pleased. The transmission feel in C mode is way different than the PDK I am used to, When it is cold and you put it in drive there is a feel of slippage. Almost like you are slipping the clutch on a manual transmission. I am not sure if this is normal or not.

Mercedes of Durham. Great dealership experience. Staff there and AMG tech top notch for me. Car was taken back there over weekend for them to address issues I mentioned. Also asked them to take a look at the tail lights as there is some residue/apparent cracking/separation around edges of tail lights. Yesterday when driving it out of driveway, there was a pop/thunk that I felt which came from front end. Saw on another forum it may something to do with the engine compartment diagonal strut (?) which may need to be sanded down so it wouldn't bind against adjacent component. Has only occurred once.
I think if I can get beyond these hopefully small issues, the car is something special. The exhaust note always brings a smile
To cec69 - the cars have a bit of a delay, especially in Comfort mode when starting off - feels like a manual. This is normal.

With regards to the thunk there is a campaign on that issue.
It is caused by the structural struts which require torquing.
Take it to your dealer and they should have the info on the fix.

Just a cut and paste of what another member kindly put on another forum. The campaign my tech found and described sounded like it matched this:
-----------------
LI62.30-P-061211
- Cracking noises when driving over undulations -
Topic number
LI62.30-P-061211
Version
1
Design group
62.30 Front cross member and reinforcement
Date
04-07-2015
Validity
190.377/378
Reason for change
Complaint
Cracking noises from the area of the windshield/ engine compartment when driving over undulations or speedbumps.
Cause
Engine compartment diagonal strut
Remedy
Modify contact surfaces of engine compartment diagonal strut on left and right.
Note:
The operation steps are described for the right diagonal strut as an example, but must be performed on both struts.
Work procedure:
1. Remove diagonal strut (Figure 1; item A)
2. Check flatness of contact surface for diagonal strut in area of windshield (Figure 2, item B)
3. Sand the contact surface for the diagonal strut in the area of the windshield using emery cloth or abrasive paper (120 grit) (Figure 2, shaded area)
Note:
Only sand lightly in the immediate contact area and do not sand down to the bare metal.
4. Repeat the work at the front contact point (Figure 3, item C and shaded area)
5. Clean and recut all threads (5x per diagonal strut)
6. Also sand the contact surfaces on the diagonal struts (Figure 4; item D and shaded area)
7. Install diagonal struts (revised torque: 30Nm)

Just a followup - my car has re-started the thunking/popping/jarring sound when going over speed bumps or turning up or out of driveways. I had the "fix" done - but obviously it wasn't lasting. Anyone have this continue or return after having the repair?

Probably best to visit the deale
Sorry to hear this, y only recommendation is to go and visit the dealer and let them escalate this to the mothership.

Thanks. I think you are correct. Such a hassle! Would think they would have picked up on this problem during development. It's as if the cars released to the public are still in the testing phase. I realize anything that is mechanical can have issues - no matter what the price. Thanks again.

I have the same problem. Dealer made some quick fix adjustment yesterday but the problem remains. Guess I will need to schedule an appointment and leave it there for the full fix described in this thread.
Have had the Edition 1 for just a month but only 750 miles to date. Like it lots more than the SLS I owned for two-years!

My 65 had a similar issue to the braces with an AMG bulletin fix, but had to be resolved permanently by an indy mechanic who replaced the bolts with the braces with different bolts...issue solved......

I recently took my vehicle in to another dealership after having the service campaign done previously - and the tech re-did the campaign - shaving more of the rough surfaces off, and replacing some of the bolts on the diagonal struts - and thus far - it seems to have worked!

Dealer in Wilmington, NC (Bob King Mercedes). I asked the tech afterwards if it "looked" like repair had been done previously - and he said he didn't see evidence of that. Maybe first tech in Durham was too gentle with the emery cloth. I did notice a "dusting" of material under the hood where he had sanded the metal components. Did he take more off than the campaign indicates? Or just do it correctly? I'm hesitant to kick my heels together in celebration yet - but after multiple trips up and down my driveway over the curb apron, it has not happened again. Fingers crossed.
