Hi boys, i have POLO 1.9 TDI 1998. This is problem: The car doesnt start if the Warm Up Lamp doesnt flash. When i turn on key and i dont wait for Warm Up Lamp lamp to flash and i start the car, it doesnt start. Then i need to turn on key and wait like 1 to 5 minutes to Warm Up Lamp to flash on, and then the car starts.

But yesterday i made mistake, i didint wait for Warm Up Lamp and the car didint start again, so as usually turned on key and waited for spiral to Warm Up Lamp, after 4 minutes spiral flashed, my car didnt start! .

What is the problem, please help me
Thank u boys!
