EQA 250
On summer I get more than 500km (310miles) of electric range and on winter (-22C) I get 50% range (250km = 155miles).
Here some videos which I have made:
Service mechanic observations:
Summer range 100% battery charge:
Winter -22C consumption test:
All too frequent malfunction warnings!
190 e, CLK, W204 estate, C 350 cdi, E 359 CDI Cabriolet and 2 E class 350 CDI night line estates.
Unfortunately we brought a year old 71 plate car from a main dealer! From the 2nd month started having issues monthly “malfunction “ warnings in the binnacle and “towing not permitted” (see pictures) when getting into the car - won’t start. Have to lock up walk away 300ft and wait 15 minutes.
The Dealership keep the car for
weeks “we know there is a problem but the diagnostic won’t tell what it is!”
have tried to reject the car under consumer law MBFS are refusing!
The final straw is a recall for a power steering issue “possible loss of directional control “

What part of Finland do you live in?

Winter is coming here is Finland, so it will be interesting to see how the winter goes, last winter we had -25C temps several weeks and a lot of snow, but EQA survived very well. Electric range decreased 50%, which was expected, but still managed to get 250km electric range which is fine, atleast for my daily needs.

One query I have for the forum relates to retrofitting a motorised trailer hitch - OPTION 550 ITEM # [SA-550]. These are not available as factory or dealer fitted options in Australia. Does anyone out there have knowledge of whether the factory genuine parts comprising this option are available anywhere in Europe?
Check more on my video, towbar function shown in section 1:59:

Reading the vehicle manual in detail there are quite a number of factors that towing influences in the balance and performance of the car.
By the way, how does the vehicle sense not to let you deactivate the tow bar once you a load on the ball? I presume the tow bar switch would be disabled if the trailer plug is connected and the vehicle can sense a trailer is connected, but what happens otherwise? Does it have a load sensor in the ball coupling?
I'm keen to see if its feasible to retrofit this feature, or at least to source the factory tow bar wiring loom if my only option turns out to be installing an after-market version of the tow bar mechanism itself. At least then some of the vehicle safety smarts may still work if programmed correctly even if that clever motor retraction feature doesn't.
Its interesting that @philipot indicates it wasn't an option for him on his 2021 model. I was checking out the more recent EQA 250+ build my car options on the UK MB site and it is certainly an option offered currently.
@Tonde1 would you happen to have access to the MB part numbers for the components comprising that option on you vehicle?

Towbar, electric, ESP trailer stabilisation • 550
When I connect the trailer plug to the car, car indicates it, and it ex. automatically proposes route navigation using trailer when I power on the car.
I also presume the tow bar switch is disabled when the trailer plug is connected, but haven’t dared to try 😃
I could do another video of full sequence involved to couple up a load and trailer, but cannot promise…as it’s now winter ❄️ Could try to do it on spring time….
Anyhow, if there a chance next time you have dialogue with your local MB dealer/service, see if they'll give you the part numbers. I've tried here but they say its not accessible on their systems as its not an option available here.
By the way; what do know about the "ESP trailer stabilisation" function? Is it a software coding thing or a piece of extra sensor hardware?
