I have a 1996 C 280 with idle problem.
When engine starts, idle goes all the way down and engine stops.
I restart engine and hope for the best. Sometimes, I need to restart engine a few times before idle stabilizes and then I can leave.

Car stops when you put the brakes at a stop . On the highway there is no problem.
The problem occurs when I start the engine and when I brake .
I already changed the OVP relay but the problem is still there.
Thanks

Maybe your car idle to low. Did your car had a service (oil change, etc)? If so let them check it. If there is no problem they can raise your RPM, so it won't stall when you brake. My C280 (V6) RPM is between 500 and 1000 RPM with brakes on.

Good luck

What is the procedure to raise the idle in the C280?

Good question!

I wasn't aware that there was a 'procedure'.

I was under the impression that this was done by the engine computer in conjunction with signals from the mass airflow sensor.

You idle problem could be a lack of fuel, MAF, or bad ignition; or all of them. I would start with simplest possibility, the fuel. Change the filter and see if this helps. Your most likely issue is the MAF, for which there are many posts about attempting to clean the unit. Just run a search on this site.

Check MAF sensor. and replace Fuel filter(If it hasent been changed for a while) plus it might be a good time for some tune up if havent done for a while too
Good Luck.
Mine used to do the same It was the MAF sensor
