    Just Joining the B250e crew

    Happy for you, it's a fun car, you will love it. You can buy aftermarket CarPlay adaptors that have reversing camera option, it's a couple of hundred bucks but usually plug and play. Although if your car was manufactured December 2015 or later (and has the NGT5 radio) you can just buy a $20...

    Hissing whining sound on acceleration

    That's a nice, long writeup, HOWEVER: it has very little to do with the milling noise. I'm really sorry that your LDU got the water leak but it doesn't mean 100% of the LDUs get broken. I'm aware of all the info in your post, scaremongering is still not warranted. Yes, we all have to check the...

    Hissing whining sound on acceleration

    I'm sharing my experience and I have the early drive unit, my car is the ED from 2015. I have enough of people scaremongering owners believing the issue is bigger than it is. Opening the rotor side while no Teflon seal available on the market other than a Chinese make is a really bad decision...

    Hissing whining sound on acceleration

    That is false. The milling noise is caused by the two cheap SKF bearings I quoted in the gearbox, not the motor. The rotor side does not even have to be opened for the fix, the gearbox comes apart without touching the rotor side. I know because my car is now silent after changing those two cheap...

    Hissing whining sound on acceleration

    These were the parts that I needed, total cost was appr. €110 - 6207+6208 SKF Explorer C3 bearings - ~€70 ( I bought them at the local bearing specialist to make sure they are genuine SKF, not fake) - 2x axle shaft seals https://www.ebay.co.uk/itm/173811815168 - ~€10 - 2l gearbox fluid...

    Malfunction go to workshop

    That's helpful but not related to the yellow error message. I like to encourage owners not to think of the worst straight away. :)

    Malfunction go to workshop

    The yellow/amber "Malfunction, visit workshop" error message is very common but it usually is not serious. A MB dealer or a specialist with MB diagnostics can clear the error. I was driving almost 2 years with that error message, I had to click OK every time I started the car. Now I got it...

    Hissing whining sound on acceleration

    I'm happy to help anyone but all the info I gathered is already available online in this forum, the Facebook group https://www.facebook.com/groups/bclasselectric and various Tesla forums. Youtube has repair videos too, I think for the Rav4. I was consulting to someone from Hungary who did the...

    Hissing whining sound on acceleration

    Just to reduce anxiety: 140km might be achievable in a mild or warm weather, 100-120km is perfectly good in January, in France. it will be more around the 130-140km range in summer.

    Highest driven milage of B class electric

    I think it had a competitive battery size for its time and for its mid-range pricing (in Europe, anyway). The Zoe hasn't introduced larger battery until 2016 and the Leaf until 2018. It's a first generation electric car, for that it's still pretty usable in 2024. As for being a town car: it...

    Hissing whining sound on acceleration

    I second the gearbox bearings. There are two rather basic bearings 6207 and 6208 on the incoming side and it spins at the same RPM as the rotor, up to 12000. They wear out and cause this whining noise, it's the same for all early Teslas and the Toyota RAV4 electric. Search for "Tesla million...

    Highest driven milage of B class electric

    Unfortunately only the STAR diagnostic tool paired with Xentry software can clear certain error codes, that's what dealers use. I'm not aware of any 3rd party tool that can handle drive train or high voltage related errors in the Mercedes. You need an official dealer or a Mercedes specialist...

    Highest driven milage of B class electric

    That's because the battery heating turns on automatically after each cold start to bring the battery to optimal temperature. The car does that at 100% or 50% of charge just the same. @LondonWdd14289ownwr suggested that for this reason he will not charge the car to 100%, but keeping the charging...

    The motor noise (infamous Tesla milling noise) is coming from the gearbox in most cases. Two cheap bearings needs to be changed, 6207 & 6208. These spin at the same speed as the rotor (up to 12k rpm) and wear out prematurely. I got them replaced last year, the car drives like new since (101k...

    Highest driven milage of B class electric

    162k km (101k miles), 09/2015 manufacturing, first registration 2016. 2.5 years ago, at 93k km the main dealer mesaured max capacity as 26.7kWh, equivalent of 5% degradation. I haven't experienced much drop in capacity since. Summer range (15-20Cº in Ireland) is around 130km in normal use (80...
