Question about 2002 Mercedes-Benz C-Class

1 Answer

My C240 when warmed up has a hesitation at low speeds or in a pull but will stop momentarily if I let off or press down more on the accelerator. Sometimes when it hesitates I hear a slight roar from under the car. I have already replaced the throttle actuator and this did not help. Wonder if it is the accelerator peddle assembly?

Before you do start spending more money on things might not need to, My personal advise,just get the vehicle for emission test to confirm whether the catalytic converter is okay or not.If you do need any further advise after that please do not hesitate to send your email.

Please be fast about checking your fuel pump. It is not giving enough fuel pressure.

Cheers.

Yes,check the fuel pressure & filter. There's about a million other things to cause this,so start simple. Ask again if this doesn't help.

On 3 occasions when accelerating from a stop or from a very low speed my 2015 Q7 momentarily lost power like it had a governor and then regained power. Any thoughts?


From what you are describing it seems like fuel starvation. This car has 2 fuel pumps, low pressure and high pressure. I'd start with fuel filter change.

Check timing of the engine is right using an engine timing light. Make sure the timing belt or chain isn't worn or slack. The head gasket could also have gone and may need replacing.

Huh? Doesn't it start out from a stop in first gear? Flush what, what belts?

When you press the gas pedal all the way down, does the engine speed up quite a bit, or stay at a very low RPM?

Does the engine miss? When did you last do a tune up? How many miles on the van? How does it run once you have reached high speeds? Any other symptoms?

Not much information for us to go on.

Sounds like a malfunctioning egr system. Too much egr gasses at once will lean out the air fuel mixture and cause hesitation in an engine. Just my 2 cents.
