Re: How to put car in neutral if battery is dead?

Good point that only the rear wheels may be locked. I've been able to get it temporarily into neutral when I have jumper cables attached, but it always goes back into park. I may play around a bit more to try to figure out exactly what triggers it to go back into park (maybe a time delay, turning th...

Re: Broken battery charger

I was thinking the same thing, but as far as I can tell the elements that need to be programmed are on the same board that had the part failure. I did make an attempt to repair the damage on the board - I scraped away what was left of the burnt up ferrite bead and put a short in its place. I then sw...

Re: Broken battery charger

Update: Well I putt the refurbished Tesla charger in and towed it to the dealership to get it programmed to work with my car, however they tell me that after three hours of trying they were unable to get it programmed. I don't know anything about what they tried or what the issues were, but my exper...

How to put car in neutral if battery is dead?

My 2014 B-class has a dead (12v) battery (as well as other problems preventing it from being operational). The dealership wasn't able to fix it, but they "manually put it into neutral" so that I could tow it home. When I got it home I connected it to jumper cables so that I could open the trunk to e...

Re: Broken battery charger

I'll keep you posted - at this point I just need to get it back to the dealership to have the new charger programmed. I may never know whether FB2 is the only damaged part or not as I have swapped the internals of the entire charging unit with the Tesla unit. I though about trying to replace the fer...

Re: Broken battery charger

Photos of the Mercedes Charger, the damage component and the replacement Tesla charger are at https://photos.app.goo.gl/XuKYn61gkeJNxFTt7 . You can view the activity stream for annotations, but basically what they show is: the first few pictures show the charger with the angled bracket on the right ...

Re: Broken battery charger

Just an update. I bought a refurbished Tesla Gen 1 10kW on board vehicle charger on eBay for $650 and brought it to the dealership so they could swap out the broken charger for this unit. Unfortunately after working on it they told me it was incompatible because it had different plug connectors. I b...

Re: Broken battery charger

Thanks for the replies. I've learned a bit more since my original post. The issue is the onboard vehicle charger (MB part # 242982062180) has died. I'm able to find this part for $5k from various MB parts suppliers, and I can find a Tesla unit (part # 6009278-00-F) that seems to be functionally equi...

Broken battery charger

My B-class refused to start, so I brought it in to the dealer. Apparently the "charging unit" went bad and needs to be replaced to the tune of $10k! I'm looking around to see if I can find a second hand unit, or some alternative that is functionally equivalent that might be cheaper (i.e perhaps a te...

Re: D.I.Y. Illuminated Chargeport

Soldering isn't difficult, but it does take a little practice. There are many good youtube tutorials, or since this project only has a few soldered components, you could probably call on a favor of a friend who is a do-it-yourselfer to help with it. You could also use a solderless breadboard to conn...
