Dear

I have    a combustion misfiring in my ( E300 AMG Mercedes Model 2013 ) in all 1  to 6 cylinders,

after testing I have the following codes(0629 - 0649 - 0653 - 0633 - 0641 - 0641 - 0645 - 0637 - 0745 - 0749)

I have changed the spark plugs put the problem is still there.

 

Also the Mercedes start stop some times it work and the other time doesn't work ( I have changed many times  the battery of the electronic Key-since I always have a massage to change the battery) but still have the same action.

 

Last, from date of purchase I felt that the car takes time to move( the gear is not acting in an immediate action) when I drive back and then I change to drive ahead it takes a while to change.

 

What you advise suggest for me to do?

 

Thanks and best regards

 

Saleh

Hi Saleh,

Sorry to hear about your troubles. I would recommend that you hook up your MB to star diagnostic scanner. That will tell you a lot more than a generic OBD2 scanner.

If you don't have access to that scanner, it may be worth taking it to the dealer or a mechaic with Star for diagnostics.

Let us know what codes come up.

Oh my

 

Seems like you have a big problem on your hand. I can try to help you by describing the meaning of each code.

 

P0629 - Usually a faulty fuel pump

P0649 -Problem with speed control lamp circuit

P0653 - Problem in sensor circuit

P0633 -Triggered with ECM or the PCM fail to communicate with the immolizer key

P0641 - PCM has detected an open faulty circuit

P0645 - Problem with the clutch or the AC circuit relay

P0637- Generic code to show problem with power steering

P0745 -PCM is not reading voltage drop correctly from the PCS

P0749 - PCM has detect some problem with the Transmission Pressure Control Solenoid A.

 

Again, very generic..sorry but yea, you might need to go down to the mechanic here
