W202 stalls at idle
 

Hello all:

96 C280... runs great but I have an annoying problem. When cold, the cars starts perfectly, however, when hot it will start normal then stall if left at idle about 5-10 seconds later. It will restart again quickly, but the cycle will repeat. If I rev it up a little, at that 5-10 second later mark, it will hesitate for a sec, then will run fine. Took it to my regular mechanic, he is very good, but apparently bought a castle and now he's charging ridiculous amounts of money, said it was probably a relay. No error codes at all. Apart from that the car runs great. Any ideas which relay should I troubleshoot?

Thanks

Changed the overload relay.... problem solved:)

just out of interest,where is the location of the ovp relay on the w202 car?

In the engine bay, passenger side towards the windshield.
It's a rectangle metal box with a fuse on top.

.... right behind the battery.

Behind the battery ? On my 202 the battery is in the trunk, the OVP is in the engine bay.

my car is a c200 and the battery sits in the trunk(boot)

where is the ovp in this situation?

mine is a C220, the battery is in the boot, and the OVP where I mentioned earlier.

In that case, I would still think the OVP would be in the left side of the engine bay, in-between the first and second firewall (for lack of a better term). The left side would be your driver's side.

It is in the engine bay, right hand side. There is a black plastic cover with a yellow sticker that reads "battery in trunk" Lift the cover and right in the middle you will find it with a fuse on top.
