hi everyone, total noob to the forum and the M5. i just purchased a 2006 M5 SMG with 39k miles. the car has been sitting for a couple of months (or maybe longer) and i had it towed to me. i tried to start it but the battery had gone belly up. put in a new battery and everything came to live. i tried to start it but the engine wont get going. the starter keeps going and going but it wouldnt start. i did some reading on the forum and found that i should hold the gas pedal down about half way and that did the trick. the engone started but it sounded like a diesel truck. i mean it was loud, sounded like something was banging inside. it also wouldn't stay running on its own. i kinda got worried and just turned it off thinking there maybe no oil in it. the oil lever shows about half way and said OK but i will have someone come out and do an oil change on the spot before i reattempt to start it again. im just really worried about the noise, anyone have similar experience after the vehicle being stored or not driven for a long period of time ??
