BTW, since I tear the boot of one of the coils, I replaced the entire coil for $40, later I discover you can just replace the boot for $12. In case someone has same problem I would recommend just replacing the boot if the electronics of the coil are ok. You can get the boot here: https://www.fcpeuro.com/products/mercedes-direct-ignition-coil-boot-mer-2761590042
Mercedes Direct Ignition Coil Boot - Genuine Mercedes 2761590042
If someone has a problem with the coil I can send you mine just pay for the shipment and get a new boot.
I just finished replacing the spark plugs. The truck starts and runs perfectly. Thank you very much for all the support and the help you bring to this community, without people like you it would be hard to find courage to repair such expensive machines. Next job is to replace oil trans for the ML and SLK. I'm confident things will be good. Thanks again and I'll keep you posted on the valve leak I found on the ML. I need to investigate how bad and dangerous to the engine is to have such leak even if it's an small one.
Hi, I'm in the process of doing the driver side of the plugs on a ML350 '15. Although is same engine as your E class, things are arrange a bit different, and had to take out some trim peaces. Also I didn't disconnected the battery and no key plugged in the truck. When I disconnected the second terminal from ECU headlights started bliking. I was not expecting that. I hope I didn't mess with my ECU or get codes later. Although I didn't had any key connected I do have keyless entry and the push button was in. Keys are not close to the truck, but not sure if that made any difference. I guess I'll see once I connect everything. Also due to tight space I'm thinking to un bolt the oil dipstick bracket. wondering If I could have any problems with that. Please advise. Is the blue bolt on the picture.
I never met this condition if the ignition switch is off. But I don't think that would be a problem for your ECU. But I recommend to purchase a MB Star or a third party diagnosis system, like a iCarsoft
From my experience, the main obstacle is the thick hardwire, I lift it and keep it at the side. If you have to remove the guide tube, the bolt torque is 5 Nm.

Sorry to hear that and you can just replace the boot.

No necessary to do any computer work.
Well... one step fwd two back. I think I broke or I alredy had a coil rubber boot tear.
Do you just replace it and that's it or do you need to do something with the computer?

我都是重复使用的，拆下来后，稍加修整就可以再次使用了。如果您需要买两个备用，这是我找到的最便宜的：http://ebay.us/6KPFFf
六寸的基本夠長了，不過我建議您买一套三个，可以应付各种情况，不比买单只贵多少。https://amzn.to/3hdeXvv
请问 intake hose clamp 哪里可以买到，看到有些人提到这个部件是一次性的？ 另外更换第6个火花塞时，您使用的1/4 延长套筒是多长的，6 in的吗
