Hi 👋

Wanted to see if anyone can help me locate a battery current sensor for my 2014 Smart ED.


Any help is greatly appreciated

Unfortunately, you image is not showing due to you being a new member.

Is this the same current sensor talked about in the link below - with some vague possible connection with bricked battery packs which nobody makes clear?

Hi.
Yes that is the sensor I’m looking for. I called Smart/Benz and I even called Bosch, they do not sell it on its own.

I tried to look for options, like a aftermarket sensor, a sensor from another car, besides the stated Fiat 500e sensor that someone else use. I found nothing, I’ve been tried eBay. If anyone has a lead on a Used HV pack with a good sensor. I greatly appreciate it. Or if someone knows another sensor from another car (besides Fiat 500e) that will work.

I’m even willing to buy from out of country. Haha.

Thank you all

Can you tell us more about what's going on with your car? We have had multiple discussions here about HV battery issues a few owners have had and we are trying to figure out the causes and connections and of course the fixes.

Thanks.

Yes, what happens when the sensor fails? Is it associated with the battery pack getting discharged flat?

Hi

Sorry for the late reply

I have a Fault codes for my BMS and sent my BMS our for repairs (was not cheap). Once that was back it was told that it had common problems and guaranteed that all is fix within the BMS. After installing the BMS back into the HV battery and started to see signs of life again as I did a quick initial start up and shut down so I can clean up and get moving. Little did I know there was a few more fault codes. These fault codes are apparently linked to the current sensor, I had a few mechanics checked the codes, clear it and it still there, looked around online and found info on the link u posted as it was the same codes as that, then sent the same codes to person that repaired my BMS and he also confirm it’s the current sensor is bad.

I called friends at Benz/Smart and no luck as they don’t sell that sensor by itself, called Bosch and they don’t sell it to anyone as it’s licensed to Smart/Benz only. So here I am looking for a good used one in hopes that it will fix my problem.

Removing and disassembling the HV battery is not fun. Did it 3 times already. If anyone attempts this. Be VERY careful.

Thanks Mike. Keep us in the loop and keep us updated. You never know - someone here might stumble onto something that could help you and vise versa. As Mercedes disappears from the picture for us, more and more of us are going to need to become more aware of what's happening with our cars.

Good luck.
