I was going to, but then I measured the area to be worked in and the various connections to the + and - terminals, and I let my neighbourhood handyman figure it out. I fail to see why it would be necessary to link the new battery to the vehicle, even if it was mentioned. It took around thirty minutes to get it on. That cubicle is incredibly cramped.

My 2019 E63s' primary AGM battery was just changed. After last August, the stop-start rarely works anymore. Just 500 yards after starting today, it kicked in. Fluids are clearly not heated to the point where they can be seen below. When the green square with the A sign appears, it means that stop start is functioning properly. Got the traffic lights working again, but then it stopped working again. Starting next month, I will get the capacitor replaced.

Several online sources have informed me that the engine compartment provides access to a cover located behind the light. Even after a quick scan, I failed to spot one!

After I warmed them up, they were nearly transparent. It's annoying, but it's condensation, not a leak.

You can't tell the two camps apart.

My 2017 SL lights are giving me the creeps due to the dampness. The weather (cold!), but maybe not quite. Although it began in the corners, the haze has now spread across the majority of the lights. I read several notes on this and thought that maybe turning on the fan heater to warm the lights will help. At first, I thought I had it figured out, but as soon as I turn off the heat, the condensation returns. I suppose water evaporates to petrol when heated, but it doesn't necessarily go out of the light. Is it absorbing additional moisture as it cools down again? Worse worse, I have just received a notice stating that my "intelligent" lighting is malfunctioning. 🤔 The installation, which involves removing the front bumper, doesn't appear to be easy, but I saw that there are second-hand units available for around £350. My fingers are crossed that this will go away once the weather warms up, since it might be a summer/winter phenomenon. Views, pls 👍🏻

Fitted a new gasket to the cover and spark surround. Those wheels on this engine aren't circular! The worn-out rubber felt a little compressed and worn out! The acoustic cover is still removed, allowing me to inspect the coils for any additional leakage. All right, tightened down properly. While I am waiting for new spark plugs at my son's place, I must say that the current plugs are still in quite decent condition. His employment with Niterra (formerly NGK) is fairly practical.

I discovered that all four of the spark plug recesses were filled with old engine oil after yesterday's oil and filter change. Unexpectedly, the coil and plugs were functioning well (and continue to do so) and there was no engine misfire; I suppose it had to have been there for some time. Cleaned it all up & picking up a replacement cam cover gasket set today. I really hope the cover isn't cracked and that's the only thing it is. Are there any other common reasons for this problem?

Thanks for making it available "over here"; I've sent this tutorial to several folks on the other side since, as far as I can tell, W203 (and similar) diesels have a thermostat problem; I had to replace mine in the first year after purchasing the vehicle. It was well worth the little investment because it not only got the engine up to temperature but also raised mpg from 40+ to 45+, making the heater operate.

Weak 12V power source. Less time to charge due to chilly weather and shorter journeys. Probably the dealer will swap it out for you.

Someone ought to know about this and have verified it!

Does anyone know who has tested for diesel leak off? I was wondering if any of the repair shops had expertise in Mercedes diagnostics using Star or Xentry.
