Customer Question

Hi, I have a pre-owned 2005 Mercedes-Benz c240 4matic. I bought it (2 years back) when it had 140,000 miles on it. I recently thought of trading in my car and thus took the odometer reading only to realize it sitting on 240,000 miles. My average driving is about 10-15,000 miles / year. I was thus shocked and I did a quick distance test. The results confirmed that the digital odometer is over calculating the distance by ~70% (I drove for 22 miles and the odometer showed 38). I spoke to the local service center and they asked me to go to the Mercedes dealership. I am obviously vary of shelling out a ton of money to fix an already depreciated asset. I can thus use some expert advice and guidance (as to the problem that may be causing this, how to get it fixed, cost estimate etc.). Kindly help.

Hi Lou, thanks for your response. Actually, the odometer was indeed set on KMS. So guess, we are good here.Thanks a lot for your help in this regard.
