Thank you for doing this! Easily found and ordered the part next day on Amazon then easily switched it out in 20 minutes. $70 and 20 minutes of work at home vs $700 and leaving the car at Mercedes all day. That's a win in my book! Appreciate you!

You have saved my life!! My daughter has her driving test tomorrow here in the UK 🇬🇧. Last night I realised that if there are any fault warnings, then the examiner will refuse to let her take her test in it. The cost including Labour costs about £300 + VAT (Tax). So I followed your instructions and bought a Auxiliary Battery, fitted it and had the garage do the code. All done at )75 + VAT. Real time video is much better, so keep them coming. Thanks again Francesca

Thank you so much for this step by step real-time video. I just replaced the voltage regulator per your video. Saved me a ton of money because the dealer was going to charge me almost $500 to do it and I did it myself having only to purchase the part for less than $100. I did not have a computer to reset the code, but once I replaced the regulator, the error message on the dash went away. Hopefully this takes care of my issue for a while. My car was a 2015 C300 4Matic. Awesome video. Saving it in my favorites!!

You'll have no choice but to get it diagnosed. At the very least get that code read. Not any code reader will access that module either, has to be a pro level scan tool. Another variable is the part itself, I'd never put an electrical part into a Mercedes that's not original. These vehicles have circuit tests that have expected results, and if that part isn't up to EXACT specifications, it won't pass/work.
