Car shaking when cold (Mercedes c180 classic 1997)

“I have a Mercedes c180 classic 1997 when i first start the car in the morning the car has a jerking problem but once it has reached the operating temperature the jerking stops. It happens again if i start the car after and hour or so. Any advice please let me know.”

Jerking can be either in the engine or the transmission. So, you have to discover in which system the problem exists. FIRST, have it scanned to see if any trouble codes are stored in the computer. Whether the check engine light is on or not, there can often be trouble codes stored in the computer to help discover where the problem lies. Hopefully yours has some codes stored, because if not, then it’s much harder to discover where the problem lies. It could be an ignition problem, a fuel problem, or a transmission problem. From my experience in those Mercedes with such a problem, it often lies in the fuel injection system since it runs fine after it warms up. So I’d check that system out first if no trouble codes exist in the computer.
