Error codes - P2073, P2026, P2017, and P2086
My car is acting quite weird recently. The whole car starts to vibrate when the car comes to a complete stop at the traffic
light. This problem doesnt happen every single time, but at least 3 times a day. Then the car seems hard to accelerate for 2
seconds after stepping on the gas, and soon start accelerate. The vibrate disappears after stepping on gas too.
A scan gave me these Error codes - P2073, P2026, P2017, and P2086.
Does anybody know that these means. ?
Thanks.

I don't know, but it looks like something might be unplugged or shorted. I only found one thread on any of your codes - P2073 - (https://mbworld.org/forums/c-class-w...ml#post5581657). Maybe somebody has some more specific information on what it could be.
Here's a general tip - you can google the code. Be sure to add 'Mercedes' or your model in case the code means something else on another car. The information I put in the post came from http://upkeep.us/OBDII/OBD2/Mercedes...t.php?art=1760. There are several similar sites out there that help diagnose CELs so you might find one you like better.
Good luck!
