My Mercedes e220 2012 stop start not working. What is the problem and how shall I sort the problem?

unreliable and dangerous

electronic faults for sure
the accelerator pedal has a sensor ..could be that stopping the car

that will need a diagnostic reader to sort out what and where

book it in for a service and a check over

the w202 has stick needles on the clocks i have tryed all sorts to try and stop this the latest thing is i took the clock out and scraped the paint off the pins the needles rest on and touch wood its been ok its got somthing to do with a static build up and the needles stick so there like a magnet or so my merc deler told me

ekectric components are gittn hot from wear--ignition and fuel pump are common with age--need to do test to confirm

sounds like someone has messed with your electrical. i suggest you call an auto electrician unless you have some sort of knowledge with electrical

Your best bet is a clogged radiator. when your car is warmed up turn on the a/c and look under the hood to see if the fan is blowing hard. if it is replace the radiator. If you are car savvy you could put in a hi flow water pump, they are pretty cheap after market and easy to install.

check your owners manuel..if you have none than purchase one.
I would say leave them alone .

has it got refridgerant in the system sometimes when it is lowthis will happen

Hi,

I would go for C class 180.

Rest on You.

Thanks.

Hi! Sounds like the key needs to be coded again, take all relvant details i.e. chassis vin number, Registration document (Title) and key to your local Mercedes Dealership and hopefully they'll rec-code it for youor replace it.
Good Luck and a Happy New Year to You and your family.
