I have a 2003 Mercedes Kompressor C230 that just recently

Customer Question

Hi,
I have a 2003 Mercedes Kompressor C230 that just recently began stalling at slow speeds and stop lights. It runs perfectly on the freeways. I let it sit for about 1/2 hour and it started back up without any problems.
Any advice?

Hello my name is ***** ***** I can help

Customer: replied 2 months ago.
Thanks and do you need more information?
Expert:  David Gieswein replied 2 months ago.

I would like to know if you have tried anything yet

Customer: replied 2 months ago.
No.
Expert:  David Gieswein replied 2 months ago.

Ok, do you have any check engine lights on?

Customer: replied 2 months ago.
No
Customer: replied 2 months ago.
It sputters and then stalls. Hard start; then stalls.
Expert:  David Gieswein replied 2 months ago.

Ok, the first thing I would try is getting a can of brake cleaner and spraying around and at the EGR valve.

Expert:  David Gieswein replied 2 months ago.

If the EGR valve is stuck open it at idle, will cause an imbalance of the air fuel mixture

Expert:  David Gieswein replied 2 months ago.

Has any work been done on the car recently? Oil change etc?

Customer: replied 2 months ago.
Ok I'll do that tomorrow and see if that works.
Customer: replied 2 months ago.
No recent repairs.
Expert:  David Gieswein replied 2 months ago.

Ok, also try spraying the brake cleaner at and around where intake gaskets are. If there is a change in the way the engine sounds then you have a leak. Same for the EGR valve

Customer: replied 2 months ago.
The only problem I have is the anti-freeze pipe has a minor leak/crack
Customer: replied 2 months ago.
Can I reach you tomorrow?
Expert:  David Gieswein replied 2 months ago.

You too
Expert:  David Gieswein replied 2 months ago.

Good morning, have you tried anything yet?

Customer: replied 2 months ago.
Just bought brake cleaner and was hoping my son in law could help but he's unavailable. Where is the EGR valve?
Customer: replied 2 months ago.
Could a leak in the radiator pipe cause this problem? Is the car too hot and that's causing it
To stall?
Expert:  David Gieswein replied 2 months ago.

If the car was too hot you would notice it on the temperature gauge on the dash. If it was overheating then yes it can cause pre-detonation. Do you have the coupe or sedan model?

Customer: replied 2 months ago.
No check engine light or temp. Where is the ERG valve?
Expert:  David Gieswein replied 2 months ago.

Do you have a coupe or sedan?

Customer: replied 2 months ago.

Automatic or standard?

Customer: replied 2 months ago.
6 speed
Expert:  David Gieswein replied 2 months ago.

This should be an accurate picture of the EGR valve

Expert:  David Gieswein replied 2 months ago.

You have not responded to my reply, how are things going?
