mercedes starts missing & jerking in the morning for few minutes

[mb54]

Hi,

I hope everybody is very well, I have bought mercedes c200 cdi 2004 2.2 diesel two weeks ago but when i start the car in the morning, i leave the car for 10minutes to get warmed up as it's diesel & been told by somebody (never drove diesel before)

After leaving the car warmed up, when you start driving, the car starts jerking,missing,jumping for few minutes, first i thought it's gear so i have changed gear oil,filter still problem was there !!!! then filled half tank & put injector in still got same problem everyday.

I went to Mercedes showroom today asked them,they said they will charge £100 for diagnose & on top of his head it could be timing chain problem it's not pumping enough oil or something ( I have no clue sorry)

Went to one of the local garage they said if it's timing chain then it could have started missing all time not just once, went to another garage they said,he will charge me £20 for a diagnose & will charge another couple of hundred if it's timing chain problem.

Would you think that it will be a timing chain problem & shall i get diagnosed done with the local garage as it's cheap & will that identify the problem ?

I have spent way more than on this car please advise thanks alot in advance.

I wouldn't leave it for 10 minutes to warm up. Just drive it. Cars are very inefficient when cold, so just get your driving half done, it'll warm up on the way. At least you'll be doing some MPG, as opposed to zero MPG...

You don't describe the jerking too much. Is it when you come to a standstill you get kicked in the back and the changes aren't smooth or something else?

Timing chain?
Maybe he meant to say fuel filter.

No need to warm it up for 10 minutes, just drive it as you would with a petrol engined car. The ECU adjusts the fuel injection for cold running.

If the problem is still evident, find yourself an independent MB garage (Cheaper than a main stealer) with an MB 'STAR' diagnostic machine. Not all generic readers will read live data. If you say where you're located someone may be able to recommend an indie.

You say that you changed the ATF. Did you use the correct fluid and put the correct amount in? Most of these cars don't have a ATF dipstick, how did you check the level? (I know dipsticks can be purchased).

I have recently just bought the exact same car and it's the same age. Mine also seems to do the same thing as you have described. Mine seems to do it more frequently the warmer it gets though and only when it's ticking over. If anyone has any advice on what could be the issue it would be much appreciated

hi,

Sorry for the late reply, i was just busy at home had a baby boy last Monday (bought this car for him )

soon you drive the car in the morning, like it kicks & starts missing for few minutes after that it goes fine.

tried to diagnosed it on next door neighbors device called launch x43 if im not wrong.
there was no errors at all.

when you stand still no problem soon you drive the car after first gear it jerks for half a mile.

MD showroom said me it may be the timming chain problem (which throws diesel i guess) or may be fuel injectors.

What will be the possible problem no body is sure about anything so we can get it fixed.

thanks alot for your time.
