Hi. Hoping for some clarity.
Experiencing like the SUV has the jitters. It’s not a wobble feeling but it just doesn’t feel smooth. Even with foot off the pedal I’m experiencing this vibration/shutter like in the cabin.
I recently had the engine and transmission mounts changed. On idle it’s perfect. Doesn’t miss a beat.
I had a miss fire and code recorded. Replaced coil. Perfect again.
I changed rear pads and left the rotors. Slight lip on edge and not completely flat and smooth. Mechanic said can get away till next pad replacement. The rear pads changed using Bembro. First time. Have always used Mercedes genuine.
the brake pedal feels fine.
Checked tyres with balancing and wheel alignment all were good.
What else could it be?
Ok Car still has a misfire. Or loss of power momentarily. No engine light though? Could another coil be on its way? Could this be the reason the car has somewhat a vibration or driving rough? Idle is smooth with no break. Mechanic is suggesting to wait till error code is recorded, so engine light to come on.
Help please. Has anyone had these issues? Also what replacement coil did you use. I’ve been told to use genuine as the Car doesn’t like other brands like Bosch etc. thanks in advance
2769060401 Is the newest part number for all cylinders expect 1 & 5 for the heat wrapping.
you can install these in cylinder 1 & 5 but order the heat wrap separate, part number is 0039978851, qty 1 is a meter of it so just cut to size.
1579060000 is the coil part number with heat wrap for cylinder 1 & 5.

just took a 276-906-04-01 out of the box and ill attach that here

I got my ML at about 82500 miles, tuned at around 87-88k and currently at 93k & very. I had my cylinder 5 coil go a couple weeks back along with the vacuum pump & pressure transducer. I had started a thread on that too just incase someone deals with those code.
My ML350 has 61K and it happened that first ignition coil failed on cylinder 3 at 42K miles and recently another coil failed on cylinder 6.
Both 3 and 6 are closest to firewall. Talked to mechanic at dealership and he said that this is common problem for M276 being installed on
W166 that coils failing prematurely cause of heat from exhaust manifold. Recommended solution by mechanic is to install Protective Hose A0039978851
on all ignition coils not only 1 and 5. Last coil that failed on cylinder 6 cost me $400 for towing, $200 for diagnosis and another $300 for part and installation.
It happened that failed coil blew off 15 amp fuse for cam shaft sensor causing all 3 cylinders on left side not working properly. Car throw 16 error codes lol
It's fixed for now but I'm planning to replace all spark plugs and coils and adding protective hoses to all coils, Hopefully this will resolve future problems
