Rear SAM Signal Acquisition Module A1644403101 for Mersedes-Benz

Got it, and haven’t installed it, I wanted a backup for the price I couldn’t beat it and I plan on having my car for a long time, and know at the age of my car they will get harder to replace in few short years, but I can say the contact and time frame was just as they said and it enabled me to go in and make changes to the one in my car now and not worry about messing it up because I have a backup,

Love it!Works great!

The Good: After multiple repair shops told me that the module in my 2010 Mazda 5 was completely irreparable, I thought my only option was to buy an expensive replacement. I nearly bought one from Amazon or eBay, but saw endless complaints about buyers having to deal with frustrating, costly programming. I found this shop through a ChatGPT recommendation and decided to give them a try. The ordering process was incredibly smooth, and they even provided a great discount code.

My fears were completely allayed when the module arrived. It was truly plug-and-play. The second I finished installing the module, the dashboard warning lights cleared out immediately! Best of all, I saved a ton of time and extra money by avoiding dealership programming.

The Only Drawback: It did take over 3 weeks for the item to ship to me. I was later informed that the delay was due to the part being out of stock. While the wait was a bit long, the excellent final result made it well worth it. Highly recommended!

Good service

As described and worked flawlessly.
