I have a CLK 430 and my left turn signal will not shut off it stays on all the time....how do I disable it or make it stop??

put you foot on the foot brake as you turn the key.

Do me a favor check the fuel injector maybe they are bad that why the odor of gaz snd the smok

In some cars, you have to depress the switch a little bit further in to start it. I am not familiar with this Mercedes but it is worth trying. In some cars, the key fob has a disabling mode if the key is not activated, the car will not start.

drill into the lock about 1/2 in then insert flat screwdriver in and turn hope that helps

The springs should have viscous fluid in them that prevents opening fast. Replace again.

Warning light - it signals an unidentified problem with your car; it usually requires the car to be serviced.

Sounds like the crankshaft position sensor needs to be replaced. They are a common problem with the Mercedes. That sensor is the one that the engine control module looks at to see if the engine is running. When they get hot and stop producing a signal the engine control module thinks the engine is not running and shuts of the fuel. After waiting awhile they cool down and the vehicle will start up again. I've changed many of them when I worked at the dealer. Tricky part is when there working and the car is running there will be no check engine light on or code stored. Usually will only have the code when the car won't start. Let me know what you end up finding out on it but that would be the first place to look and probably the cheapest.

Assuming you already have checked there is spark at spark plugs. It sounds like starving fuel. This is a problem with the Cold start valve not working. Its function is to spray fuel to assist the start. The valve needs to have a turn on signal from the ECM which reads the coolant sensor before giving a signal to open the valve.
1- If the coolant sensor gives erratic voltage then ECM will not turn on the cold start valve.
2- IF the ECM give the signal to turn on, the solenoid inside the valve gets stuck then the valve could not turn on.
Troubleshooting is time consuming that is why the cost is high because replacing the wrong expensive parts could not make it work and who bears the cost, plus the shop reputation.

yes i have my blower went out.It is your blower

Hi Joe here, The problem with your a/c is a sensor. Most likely the pressure sensor. You need to have the vehicle scanned to find out which sensor it is.
