It’s supposed to be going in for a diesel software update tomorrow but not sure that’s a good ideaThat's good but I wonder why it appears inconsistent, although I hope it stay like that for you.
Sorry, I had not seen you response with a picture when I posted my last comment.
If your Diesel software update is being done by a Main Dealer (I always use Main Dealer) then maybe they can explain why you are seeing so much inconsistency.
The only time mine does not turn the engine off if I am stopped, is if the Hybrid charge is showing less than about 35%.
the diesel software from what I’ve read detunes the car to reduce NoX And increases adblue usage similar the the Vw emmisions problems a few years ago so I’m not overly sure I should be taking it in for that doing at all - I’m going to get it booked into a Mercedes specialist to see if they can help replcing the AGM battery has definitely made a difference but still not right it seemsSorry, I had not seen you response with a picture when I posted my last comment.

It’s worked fantastic all weekend this morning back to its old ways hahaIt just seems strange that it is so inconsistent. I was pleased for you when I read your message timed at 6:03 this morning, only for it all to change a couple of hours later.
You make an interesting comment, is this 10mph speed what other members experience? I ask this as we have a 2021 petrol hybrid and the petrol engine most definitely does NOT cut in at that speed or anywhere near it. Most of our journeys are around town but my wife does express her frustration with a beep noise that comes from the car whenever the vehicle exceeds the speed limit.. I wonder who set that option?? I only mention this as the petrol engines does not kick in, even at 30mph, plus there is a slight gradient outside our property and the boss does not hang about when pulling up that hill but it is still just electric horses that pull our trusty steed. So far we are averaging 141.2mpg (UK) and the fuel tank indicates being 91% full. The car was filled up when it was delivered and has so far never revisited a fuel selling em poriumYes. It will set off and drive up to 10mph before the engine starts.
Also if I am driving along at any speed and the momentum is keeping the car going, the engine will turn off and then use the hybrid system to keep going. With careful use of the accelerator and keeping an eye on the charge/discharge dial it will run on electric at any speed. It is only when setting off that it is limited to 10mph.
No drain on the battery it’s in with a specialist in a few weeks so I’ll wait for them to let me know what the issue is but yes it’s very intermittent seems to not like coastal routes hahaThat's great for the weekend but why has it changed today.
Have you got an intermittent wiring problem?
I replaced the 12v battery and I had a good 4 days of it driving like a hybrid but come Monday morning it’s severely hit and miss maybe gone onto electric twice while coasting in 400 miles and sitting on dieeel at lights etcHi,
Yes, I picked up the car from service a week ago.
Now the battery works perfect!
No more errors, all sections has a similar voltage. More over I saw a 99% of charge!
Whole process took 10 days.
The disassemble process is really very hard. But the weld looks as from factory.

Koteckis I think will be a 350e plug in petrol hybrid - which makes sense they changed to plugins after only a few years of mild hybrids given the trouble people seem to have with the mild hybrids - mine is inconsistent and it’s baffling me typical electrical issue never consistent new battery is sitting at 12.7 volts after a night off there’s no drain on the battery my next step prior to it going into a specialist Friday is check the aux battery as that has to hold up for the millisecond between the 12v main battery and the 130v he batteryWe haven't solved the problem because one day his car behaves the same as mine, the next day it is completely different.
Incidentally, is your car plug-in as well?
Mine is the latest hybrid and the E-class range of hybrid is: Saloon: E300e petrol, E300De diesel. In the UK you can only have an estate with the diesel option.Koteckis I think will be a 350e plug in petrol hybrid - which makes sense they changed to plugins after only a few years of mild hybrids given the trouble people seem to have with the mild hybrids - mine is inconsistent and it’s baffling me typical electrical issue never consistent new battery is sitting at 12.7 volts after a night off there’s no drain on the battery my next step prior to it going into a specialist Friday is check the aux battery as that has to hold up for the millisecond between the 12v main battery and the 130v he battery
