Hi,
Just had my 2013 c220cdi serviced at a dealer, being nosy had a look at the dash cam after and noticed they had a computer screen on a trolley and connected it to battery terminals in engine bay.
What is this device ? Only had oil and brake fluid done.
I noticed MPG readings were ------ but everything else seems to be unaffected.
I did however think the car felt a little sluggish at one point and it made me think did the car have a remap, which is now wiped?
No big deal just curious is all.
