I have a Volkswagen Polo that does not start I put the scannner and I do not give me any answer to say that I check if it is connected and DLC and if the swicht is on the Swicht already check it and everything is well connected and ignited the swicht, something else when putting the swicht does not turn on the light of check all the fuses are fine, this car was stopped for many months without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use without any use. I had outdoors I have come to attach that it can be ECU but I have my doubts.
