It is under the air filter. Remove the air filter, the cold start valve is located in the middle of the intake manifold, very close to the valve cover. You can identify it easily as there is a blue coloured electrical terminal connected to it on one side and a fuel line feed on the other, which leads back to the CIS fuel distributor.
May be (probably) the cold start valve. I'm not sure how to check it to see if that's the problem. They are expensive even if purchased aftermarket. Good luck!
The 1985 Mercedes 190e could have a stuck choke. Check the choke mechanisms to start with, to see if that's the problem.
Cold Start Valve. Cold start valve. I do not believe there exists a "cold start valve"
Make sure the cold start valve is working properly and not seized up.
Remove the Air cleaner completely and you will see the Cold Start Valve underneath with the wiring plug attached to it. You can instantly recognize this valve from the Allen Key screws that bolt it on to the manifold. John T
Does the engine turn over but not start or it does not turn over till cold? If the latter is the answer then your kick start is the problem. REPLY The car turns over but wont start.
Cold start valve is bad or possibly blown fuse in overload protection relay
were is locate the cold start valve
This is probably a separate issue. Most 190e's with the 2.6l engine are known to be rather troublesome in cold, and wet weather. As I live in Maine, we get a lot of that... The most common solution is to replace the cold start sensor. This will keep you from having to give your car a shot of starting fluid every time you want to go somewhere.
it is probably the heater control valve see my tutorial on this at http://www.benzworld.org/forums/w201-190e-d-class/1358590-troubleshooting-mercedes-benz-190-e-d-210-tempmatic-climate-control-system.html#post2716281
