Vibration on 2012 BiTurbo
Car has a quite noticeable (irritating) vibration starting at around 75mph.
Tried re-balancing all wheels/tires, different set of wheels/tires - still vibrates.
Does not matter whet gear I am in - still vibrates at over 75 mph.
Must be somthing in the wheel rotors or hubs. Anyone seen anything like this on their cars?
Dealer is stumped.
Thanks

Did anyone check bolts connecting drive shaft to the differential?

I have lived through a similar situation on my 2005 E55.... I brought my car in because it had no power when my put my foot into it (as if the super charger was no longer working). It sat at the dealership for "2 weeks" while they were replacing things left and right and could simply not figure it out. Finally, they found some wiring issue that was causing the problem.
Personally, I think for the most part technicians end up debugging issues through trial and error (in my early days as a computer debug tech we called it the "shot gun" approach) when their tools do not tell them what the problem is.
My 2012 E63 comes in soon, so I will certainly test it for this issue.
I would also be interested if you ever went back and closed your situation with your dealer (never answered in your other thread) and what they had to say for themselves.

Pirelli or Continental?
To answer some of the other questions on the post, my car has been en many times. Tried alignment, "super good" balancing - nothing helped.
Finally gave up and put on winter snow tires - Bridgestone Blizzaks that are super sof and narrower than OEM tires, and now the car finally drives like ... well... like a Mercedes!!
As I mentioned erlier, swapping to slighly softer, narrower, and taller Blizzak snows, dramatically improved the situation.
I think this confirms my theory that the combination of wide, low profile tires, stiff suspension bushings and shock absorbers, make the car vulnerable to the slightest irregularity. Bad design. Mercedes knows better given their long history of autobahn cruisers.
First of all, I was happy with the new ECU. On top of that, I found they fix the vibration issue by doing alignment adjustment.
I used to use Pirelli and not with Bridgestone Potenza S-04.

So the problem was fixed with alignment?
Also the dealer did a tune on your car what did it cost and what dealer?
I went thru my service manager (at FJ Fremont) for ECU and cost was $1200. He told me if for some reason ECU got re-flashed in the future at dealer, he will arrange to get the tune back.
After been driving with vibration for couple of months really makes me appreciate when the problem gets fixed.
My car still vibrated on OEM Pirellis after driving 100 highway miles.
Does NOT vibrate with soft winter tires.
My WHEELS are not bent or flat,, as evidenced by the fact that the snow tires mounted on the same OEM wheels that the Pirelli summer tires were mounted on (and vibrated), work just fine.

I changed from Pirelli to Bridgestone Potenza S-04. For some reason, it was off balance after tire replacement. My car vibrates around speed of 75-80 miles per hour.
After two trips to dealer, the problem now is fixed...........it feels very good driving my car vibration free and upgraded ECU adding a bit more enjoyment.........

You can ask your service manager to check the balance.
I have a 2010 E63. I had the stock OEM 18 in AMG wheels. WIth these, it was a minor vibration above 75. Almost not even noticable so I lived with it.
I recently bought new 19in OEM performance package wheels. Had them mounted and balanced today. Now there is a pretty substaintial vibration 75+. The rims are not bent - they are new. The tires are also new - stock contis.
I am going to go back to the dealership and have them take a look no doubt. I am sure they will try rebalancing but after reading this, I don't think that will solve the issue.
Now here is some more information. I believe there is a seperate thread on this also. When turning the wheel left or right, there is a clicking noise that is definatley not normal. I am thinking that may be causing the issue and now that I switched to lower profile and larger wheels/tires, it is being even more pronounced as evidenced by the vibration.
I believe some people had their struts replaced to fix the issue...any one recall this thread? I can try to find it.
Maybe the strut issue is causing the problem in your car also? I think it was the struts that were replaced on others cars.
This is super annoying! Please keep this thread updated with any progress - I will do the same. let's hope we get this fixed - i bet it is the same issue with our cars.
