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?

Thanks and do you need more information?
Expert:  David Gieswein replied 10 months ago.

I would like to know if you have tried anything yet

Customer: replied 10 months ago.
No.
Expert:  David Gieswein replied 10 months ago.

Ok, do you have any check engine lights on?

Customer: replied 10 months ago.
No
Customer: replied 10 months ago.
It sputters and then stalls. Hard start; then stalls.
Expert:  David Gieswein replied 10 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 10 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 10 months ago.

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

Customer: replied 10 months ago.
Ok I'll do that tomorrow and see if that works.
Customer: replied 10 months ago.
No recent repairs.
Expert:  David Gieswein replied 10 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 10 months ago.
The only problem I have is the anti-freeze pipe has a minor leak/crack
Customer: replied 10 months ago.
Can I reach you tomorrow?
Expert:  David Gieswein replied 10 months ago.

Don't think that would cause this problem. Yes, I will be checking my phone for your response

Expert:  David Gieswein replied 10 months ago.

Leave the ticket open till I have answered your question

Ok thank you and I'll be in touch tomorrow.

No problem, have a great evening!

Customer: replied 10 months ago.
Ok and how do I do that?

You too
Expert:  David Gieswein replied 10 months ago.

Good morning, have you tried anything yet?

Customer: replied 10 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 10 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 10 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 10 months ago.
No check engine light or temp. Where is the ERG valve?
Expert:  David Gieswein replied 10 months ago.

Do you have a coupe or sedan?

Customer: replied 10 months ago.
Kompressor 2 door C230. 2003
Expert:  David Gieswein replied 10 months ago.

Automatic or standard?

Customer: replied 10 months ago.
6 speed
Expert:  David Gieswein replied 10 months ago.

This should be an accurate picture of the EGR valve

Expert:  David Gieswein replied 10 months ago.

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