I have a 2008 E350 4 matic. The stat ignition is taking more than regular time to get the engine started, and that happens when I start it after along time of turning it off. So if try to start for the first time it takes too long, and if turn it off immediately after that and it works (starts) perfectly. I the car gets heated up the ignition works perfectly. Sometimes, when the weather is hot out here is works immediately. Please let me know if you have any idea why the ignition it taking to long and weather it is going to affect the car or not. Thanks

Do you mean slow cranking before starting or length of time before starting?
