No idea on that one I'm afraid!!
I set pre heat again this morning and there was a decent frost on all of the cars. Mine was last belt and wa at departure time and 100% battery so 16a is most definitely sufficient!

I wonder if on 16A it directly powers everything via the charge point but on 8A or 13A it powers from the batteries and recharges them which adds some inefficiency?
"Mine was last belt and wa " - that's what you get for posting using the phone!
Meant to say "Mine was fully charged at departure time"!

Rear tyre wear
Hey everyone. Yesterday I received a tyre pressure warning in my OSR tyre and took it into the shop for a closer look.
After only 12k miles over 11 months, with an estimated 70% of those miles done on the motorway, both rear tyres (Bridgestone Potenza 245/40/18) had worn down to 2mm but even worse was the OSR had worn through to the cords on the inner shoulder - causing the leak.
The fronts are in great condition with over 5mm remaining all round.
So this post is to say firstly, as we are now in winter, everybody go check your rears! And secondly, what kind of distances is everyone else getting?
Our other car, a BMW 5 series MSport had its rear tyres (Michelin) changed after 28k and my previous MB, an SLK covered over 20k without needing a change when it went back at the end of its lease.
Maybe it's the combination of the huge weight at the rear and the instant all on torque, when you accelerate?
Anyway, the last time I had Bridgestones was on an X5 and I remember those being soft wearing too....so I am now on Pirelli P-Zeros, let's see how it goes.

I'd be surprised if the car did something different depending on whether it was charging at 8 / 13 / 16 amps.
Personally, I suspect that the initial current draw is very high - say 30a (for example) for the first 5 mins or so to warm which then reduces gradually as it re-circulates the heat and adds only a little - something like reducing from 30a at the start of pre-heat to 15a after 5 mins and to 10a after another 5mins. This means the 16a supply can replenish the battery back to 100% before you get to it but the 13a brick charger can't.
It's only a theory - I'll have a look at the battery charge state on Mercedes Me app at various points tomorrow morning before I leave to see what the charge state is!
My original Conti's on the rear lasted very slightly over 10k miles and 9 months (2 months early on I did no miles due to not having the car - charging problems). They were down to the cords over about half of the width which was a real surprise..Hey everyone.

After further thought on this I think the internal charging unit is smarter with how it does the pre-heat but if you use the external charger it does indeed feel like it powers the climate control using the HV battery while also trying to charge it back up.
It seems a Nissan Leaf will pull the maximum it can from a 7kW point so if you have a 3.6kW leaf it will pull that, if you have a 7kW leaf, it will pull that....the better charger leaf will be quicker to climatise. Neither cases does it use the HV battery.
Loving my new 350e sport estate collected a week ago can believe it was supplied with no floormats fitted aparantly only come on amg upgrade anyone else notice this? Facinated by the economy but puzzled by when I first collected the car it started up at 19 mile electric range since then charging at home off plug starts off just 12 miles - not using a pre heat etc any ideas on how to get range back up to starting at 19 miles? If its the cold does parking in the garage help?
The range guess-o-meter is purely there to confuse drivers. Assume you can do 5 miles on batteries in the winter and 10 miles in the summer and you should get a little extra range than you've assumed but probably not much. Unless my batteries are substandard.
My lease company put their mats in. They're OK. Not AMG trim, I'm sure, but better than nowt.

Quick one - will post something proper night. But a 16A charger is not sufficient to keep the car at 100% during pre-heat. I've a dedicated Rolec 32A charger. I know it limits to 16A but here is a picture during preheat
(Bugg3r can't upload on iPhone). Anyway it shows 91% charged and 3.7kW charge power
I'll be setting it earlier tomorrow...

I was down at 93% at point of departure this morning - first time I've known it to be below 100% in the 12months I've owned it. It was -3.5C with a very thick frost on all of the other cars. Mine was completely defrosted and warm so I'm fine with a slightly depleted battery!
It appears to depend on the outside temp / how much frost it has to clear. Mine was at 93% this morning but it was nice and warm. I've never known it below 100% at point of departure with pre-heat set.
Setting earlier will mean it's cooled down in the time the pre-heat isn't running, I'm fine with a lower battery and a warm car!!
Note sure the leaf quite works like that. Yes, it will draw 3.6kW (16a) or 7kW (32a) depending on the model and the charger but I don't believe the pre-heat / climate control is any different on either car (i.e. higher powere climate system on the 7kW Leaf Vs the 3.6kW Leaf..
I'd also be very surprised if the car climate control system was configured to draw power directly from the charger cable / circuit if plugged in but from the HV battery if not plugged in - it's much simpler, cheaper and more reliable to use the same system (i.e. the HV battery) to power the climate control at all times and use the external plug to re-charge the battery at whatever rate it can. This would be the same as the Merc.

Mine didn't have any mats in it either. Couldn't believe it. The studs are in the floor for them. I kicked up a fuss and was given a set of the black tweedy jobs. I think they are about £100 from the parts department.
The electric range based on what the previous trips have been. If your commute is the same every morning and you get 10 miles into it on electric, it will say 10 miles the following morning. You won't see 19 again I'm afraid unless you have a 19 mile downhill commute in 20 degree temperatures.

My supervisors does have a heated steering wheel
Today I plugged in at 07:10 at 13A, set the pre-climate with the button in the car (which also means I can turn off the passenger heated seat) and by the time I left at 07:50 it was still doing it's stuff and charge was down to 87%, not too bad, was lovely and warm.
Only got about 9-10 miles of engine off on my 19 mile commute though.

Mine came with mats from MB leasing, proper Mercedes ones. If our company had stayed with Arval it would have come with thin crappy Arval branded ones.
Yep, my wife has a Leaf also and I think the heated wheel is permanently switched on!!My supervisors does have a heated steering wheel

Question about the pre-heat: is it always 15 minutes or is it smart and adjusts the time to the outside temperature? I e if I set the start time to 07:45, does it start heating at 07:30 or earlier if it's really cold out?
Wife's Leaf was down at 98% yesterday morning at time of leaving despite being plugged in. Looks like pre-heat on pure electric cars is similar in operation to the Merc!
I believe it always activates 15 min's prior to and runs on for a maximum of 5 mins past the set departure time. It just varies the heat output / seat heating during that time to ensure it's at the right temp for departure.
Not as cold this morning so mine was warm and 100% charge at departure time!
