2023 EQB 350
New owner; several questions
Hey everyone!
I found a great deal for a lightly used-lease 2023 EQB 350 that barely had 6800 miles on it. The carfax was clean and it did have that battery recall on it, so I took it in to the dealer to get the recalls taken care of and tire balanced. I am needing help from the community getting my bearings around mercedes maintenance since this is my first mercedes.
-I called two different dealers and for the "service B", one is charging $850+ and another dealer is at $450. Looking at what service B entails for an EV, I can do most of the work, but I would want them to handle fluid top-offs and mechanical inspections. Has anyone here tried to do some of the work themselves, or others at a 3rd party mechanic shop for basic maintenance and tire rotations?
-I have to check if my vehicle has the older black cap for the coolant, I just found through these forums that it is a problem with the EQB coolant caps. My EQB was assembled late 2022 and delivered early 2023 so I'm assuming I'll have that issue. Are there other things I have to be aware of and to fix early on?
Thanks in advance!

[img alt="Here is my coolant cap. The part # is correct, but unsure if previous models had the same part number.

You should do the services yourself. Dealer service departments are losing a big chunk of revenue because EV's need little service. They have dreamed up ways to get you in the service bay for a 'check'. If you know even the most basic things about vehicles, do it yourself. The cabin air filter is accessed from below the passenger seat side dash. Check the tires, coolant, top up the washer fluid, do a general check with a good flashlight. The brake fluid at two years is a stretch for needing to be done, but you could out of an abundance of caution. My fluid is still at 0% water at over three years old, meaning I'd be exchanging it for essentially identical fluid. The EQB is a great little SUV...hope you enjoy.

The two dealers in my area charges 1k for service B. I looked up what the work includes, air filter changes and brake fluid. **** the price gouge. I googled how to reset the counter since I saw the brake fluid was done in the last 6 months. Then again I'm reading conflicting stuff like it could void your warranty. Say if you had a brake failure they could argue that it's because you didn't perform service B.

While under factory warranty, you're not going to want to be play any games with the services/intervals. Have service done according to time and mileage, in most cities, there are two Mercedes-Benz dealers, and one will have the better reputation for cost of maintenance/repairs, I'd go there.

I agree with high line autos on searching around. My local dealer was $855 but a second dealer was in the low 400s. And I too looked at all of service B.. I think it could be fine for a lot less I agree, at least closer to just under 400.
I have a used vehicle but it’s a 23’ with 7K miles on the nose.

Also a newbie. I haven't taken my 2025 EQB in for service yet, but one reason to take your vehicle in for the minimum Service A and B is avoid warranty issues. The maintenance book states that desiccant cartridge for the HV battery needs to be replaced at each service interval, but no where else do I see that on the list of services performed for either Service A or B. Fortunately, I have the first 2 years of service included with my purchase, but would have to pay for a year 3 Service A before my lease ends.

Scared of Service
Hi. I‘m in the same boat. Have bought it outright and it’s running with no problems. Knock on Wood.
I just had my second Service done and I feel like it’s not worth it for an EV to go to MB. With a ICE Car it might be different. You can feel the difference after a Service there. With my EV, not so much. On the Invoice(0.0$) it states several Items but not what should have been included in Service B.
I miss any mention of Breake Fluid work or Material.
Missing any mention of Cabin Air Filter change in labor or Materials.
No mention of any check and result of the High voltage Battery Check.
The attached Checklist where everything was checked ok is a ICE Car Service Sheet. Nothing in it is EV Specific.
I feel totally mistreated here again.
To me, it only shows how less EV knowledge is in these Services Garages. I will skip any other Services from now on. Everthing that needs to be done can be done by me or if I choose so, a regular garage near me.
Overpriced and suspicious in the actual Work been done.

Correction!
I found the details for the Break Fluid change and one Cabin Filter (aren'ed there two?). I skipped a Page from the Report on the Way home. Still not going back.
