Purchased a CPO Benz with a Mileage Blocker Installed

[RoyalOac]

Hello all,

I would like some advice from you guys as I was very shocked to find out this afternoon that my CPO Benz 2015 E350 had a mileage blocker installed previously.

The story is;


Car purchased May 2018

Had heart surgery so couldnt drive for few months

Last Tuesday, the check-engine-light had came on along with a host of problems such as the reverse camera not working, the brake HOLD not working, and MPG tracking not working. I took it to the dealership on Thursday and they dealership was not able to figure out the problem all weekend. Fast forward to today, I get a call from my service advisor that the head tech had found a mileage blocker installed in the cluster. They told me that after unplugging the device, there was an additional 7k miles added to the odo reading.

They aren't pointing fingers at me, nor are they stating it wasn't me, but said that the sent all the information to Benz to figure out when this was installed. I am clearly fuming at this point and know if the Benz has the know-how to figure out when this was installed, I will clearly be vindicated.

I want to ask you guys, what kind of compensation is warranted? I clearly don't want the vehicle anymore since you never know what kind of problems I can run into later and the 'CPO' already left a bad taste in my mouth as a BS way to sell a used car. Do you think the dealership should offer me a full refund? Any advice and thoughts are welcome. Thank you
